Describing Different Types Of Environment Environmental Sciences Essay

Describing Different Types Of Environment Environmental Sciences Essay In our surround there is living and nonliving things which are together form life. Hydrosphere, atmosphere, and geosphere are the component of the environment that surrounds us. Hydrosphere, the wet environment that consists of water, covers most of earth surface. Sea, rivers, lakes and under surface water are all aquatic environment. Land or what is called geosphere composed of deserts, mountains, hills and level lands. Atmosphere is around the earth and consists of gases such as hydrogen, oxygen, nitrogen †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦etc. The interaction of all these make up a liveable surround with unique properties that correlates organisms. Not all environments suitable to us. Deserts even cold or hot ones do not correlate individuals. However some organisms live in these environments because they have special adaptation to their environment. To us, we the humans, prefer to live in cities where comfortable civilization life. However others dont prefer that because of the crowed, noise, and pollution that emerge from humans activities. They used to live in villages where more green lands, natural landscapes, and more quiet than cities. To divide environments sorts we can mention 3 kinds of environments Natural, industrial, and social environment. Natural environment: Include water, light, land, air and all organisms that live in nature. Industrial environment: Include cities, villages, factories and all humans synthesis. Social environment: Include authorities, universities, schools, companies and other establishments along with their output legal and their communication ways. The future of the environment is in danger! Human made environment standard for the acquisition of the bulk of the land and it is natural resources and resources of crude, instead of improving the earth and know how to utilization it they attrition the land resources and depreciation capacity o rehabilitate themselves and make up for lost natural environment cannot in any way to adapt to the devastation caused by human, and cannot mechanisms of years of natural cope with waste and depletion of resources and polluting it is vital. The effects of the present inequity in appearance and shone on the horizon the alarm uncle everywhere in the world, and suffered all either from a decline in production and the abundance of food, as a result of the growing stunning in population, water shortages and pollution of water sources, or from air pollution and climate change due to development industrial and energy use, without concern, which has increased the proportion of harmful and toxic gases in the atmosphere such as oxides of sulfur and nitrogen, high temperature of the earth, which are threatened with drowning if the melted ice of the Arctic. And the body of this in the spread of poverty, famine, unemployment, disease, degradation of natural resources of the planet. Here exploded question filled the world, north and south, about the capacity of the land and the environment on probability, and the continuing rights in the ignore for its self-destruction for himself and his children and grandchildren and to the earth. What the differences between the new environment and old environment ? (environment in the past and nowadays ) There is a lot of (are many differences) differences between the new environment and the old one. First of all, the old environment could be very difficult and simple (in the past the life was simple, but it had a difficult way to live) . For example, how people was lived in that environment! They lived in the tents and they have not any electronic machines, like a computers, televisions, telephones, dish washers and washing machines. They lived in a simple life without any problems about food or clean clothes. (For example they can cook by fire). Also they can clean their clothes by their hands. In the past, there is no cars they move by animals, like camels or horses. Its hard to get anything by yourself, people should help each other. On the other hand, the new environment thats where we live now, its more easily and comfortable. Now a days after they discover the oil, people have a lot of electronic machines and can benefit them in many ways. For instance, the computer can help everybody to finish their works or research for a lot of things, like news or weather. Generally, people was very happy in this life. Which is making their life more easier and faster. Finally, I cant say that people who live currently in this time are better than the others. In this life every time is different from another. Maybe people in the future will be better than us.

Many people do not keep the environment healthy, because they do not have any responsibility about our environment; so many pollutions residues leave unhealthy life and spread out diseases. In this essay, I will show you some examples of pollution. First of all, there are many people throw plastics in parks, streets, water, etc. While, plastic is the most dangerous material from other pollution. For instance, the disadvantage for plastic cannot be Disintegrates until millions years. Then it will be lagging material under the land, so the water cannot pass inside the land (abdominal water). Unfortunately most of markets or shops use plastics for baskets or use like bags for customers and do not care for Recyclable, so they throw it in every ware. For example, Ajman supermarket and some other markets contribute the plastics bags like a gift, so they help to damage the environment without knowing. In addition, all of us have to protect our environment honestly and think how to solve plastics problems to live in beautiful earth. Furthermore, the water pollution are also keep contaminant environment such as when people throw the rubbish inside waters then all sea animals will die, for they will eat some dangerous chemical material. Next, some countries prefer to build chalet or Industrial Islands near the sea, it is wonderful and nice landscape, while it is affect for waters into bad environment. In fact, all sea animals need to quietly place and clean water, so when we use some chemical material or put sands to build island, its help all animals to immigrate to another quiet and clean place, or kill them before immigration. Moreover, sometimes the petrol will leakage from steamship into the oceans, and it will make lagging layer above the water then the oxygen will never receive under the water, so all sea animals will asphyxiates and will die. Finally, if we are ignore the water to clean it and keep it healthy, all sea animals will be endangered, so we have to keep our water environment healthy to feel comf ortable. Meanwhile, the land pollution is one of dangerous pollutions in our life. Firstly, the most pollution resource in the world is human, because they can control the earth in every ways either is healthy earth or dirt environment. Secondly, when we buried all rubbish under the earth, it will invent new dangerous diseases for people in every run. However, if we burned the rubbish or use the explosives in war, it will affect for the air and it is possible to pierces the ozone layer, so it will make the air pollutions. To summarize, all detonations and rubbish make bad healthy, so you have to cede these dangerous material. In conclusion, we have to find the solutions for these pollutions to be wonderful environment. The relation among organisms: The study of the environment related on studying the relation between its elements and how do they affect each other, so the environment creates a surrounding where the life exists and mutual bonds appear in a very unique form. The relation between organisms is the most important relation that occurs in any type of environment. Furthermore, this relation consists of combined processes that start with specific element and end up with another element. For example, the food chain among organisms starts with self feeding organisms such as plants then herbivores, organisms that eat plants, and finally it end up with carnivores, organisms that eat the herbivores. This complex relation happen by nature, so it is innate that why I always call this relation the battle of existence. Another type of relation that takes place in the environment is the relation between the organisms and the environmental components. For instance, the environment that suffers from food shortage, dehydration and oxygen depletion has no life. As a result, the surrounding that encompasses all the biological factors, such as water, air and food, is very important for survival. Human did create a special relation with the environment since the Stone Age. For example, people utilize the environmental resources to create their own lifestyle. The use of the animals skins to make a fashionable clothes and the use of plants wood, mountains stones to build their own houses with a beautiful designs. All these represent the vital bond between human and the environment. Environment is a commonly used word that is related to the living beings components and other components and how they interact together, in order to exist. It regulates the relationship between these lifes components. Human being is one important component of the environment it is related to the other parts of the environment in how he or she adapts to live within the different environmental conditions for example climate, water, food in addition to the society. As a result, to talk about environment, it can be summarized in the middle that the living beings live in and how they interact in this middle and together. As the previous mentioned, and with regard to human being effect on environment as one component of the environment, he or she plays a very important role in develop, create, rebuild and remake the natural environmental resources such as agriculture, manufacturing and so on, The natural environment or the basic one is a complete system in other word for example the color of the sea water is a reflection of the sky color another example is the volume of oxygen in a place is related to the volume of plants and woods in this place. These instances describe the beauty of our mother the environment. The differentiation in earths environment creates different types of divisions. For example, water environment has its own world. From the living beings those live in passing by its climate areas which affect in the type of the living beings that exist there reaching to the effect of this environment on other types of environments. The same example can be put in land environment and air spheres one. Solutions for pollution: 1* we can use the solar energy instead of energy generated because a solar energy is free from pollution and it can save the environment from it. 2*we must to reduce from forest fires it can help us to keep our environment from pollution. 3*we should to build the factories out of city and away from people. 4*It`s not allowed to throw the waste in the sea specially the waste oil it`s very bad and harmful for view of the sea. 5*good way to reduce from pollution is to grow a lot of trees in the city .They can get fresh air and moves us away from pollution. 6*put filters in our cars to reduce from pollution. 7*we should also to reduce from use the plastic it`s very bad and it can make pollution in environment.

Physics of Pool :: physics sport pool billiards

Physics is the science that allows us to understand the fundamental behaviors of the universe. It can be explored at the macroscopic and microscopic levels, giving insight into the way objects interact. Here we will take a look at how physics can be applied to the game of pool. Almost all of the different aspects of pool can be explained through physics, and a better understanding of these fundemental principles can aid in performance playing pool. In the game of pool there are sixteen balls, one cueball and fifteen physically identical numbered balls. While there are many interactions between all the balls on the table, in order to simplify things we will only look at the interactions between the cue ball and the first ball it strikes. These principles can be expanded to evaluate the entire system of balls on the pool table. In order to evaluate the physics of pool, first the measurable values of the system must be collected. Parameter Symbol Value Cue ball mass m1 1.6x10-1 kg Cue ball radius r1 2.79x10-2m Ball mass m2-m16 1.7x10-1 kg Ball radii r2-r16 2.86x10-2 m Coefficient of friction  µk 0.027 Knowing these values the Motion, Work, and Energy can all be derived. The motion of the balls can be catagorized into two general catagories which are collisions and spin or rotation. Here the focus will be on collisions between the balls. The spin can have a significant effect on the motion of the ball, but due to time constraints and complexity of the science of it it will not be addressed to much detail. "An elastic collision between two objects is one in which the total kinetic energy (as well as total momentum) of the system is the same before and after the collision." (Physics for Scientists and Engineers) In a collision between the cue ball and another ball, since the masses are so similar the resulting angle between the vectors of the balls is approximately ninety degrees.

College Tuition Essay

In today’s society, the idea of a college education has become less of an option and more of a necessary requirement and is commonly considered the only way to acquire a successful career and life. There are many careers, in which a college education is not technically necessary, that can often be just as or even more successful. With the cost of college tuition increasing with every passing year, the controversy of whether college is really worth the cost and burden is growing too. If our society wants to continue displaying a college education as somewhat of a necessity for success, I believe the cost of it should shift to being a more realistic price, suitable for the majority of students striving to go to college. Most high school students feel pressure by not only the family, but also peers and teaching faculty to go to college because it’s â€Å"the smart thing to do†, but some may be hesitant to choose the college route because they believe their experiences will be different and the benefits of getting the job and making all their money back won’t apply to them. Economic research concludes that more students would gain from college rather than opting out from it, and choosing a different route. Yes, there are many careers that require little or no further education after high school that may be considered successful jobs, such as construction and more hands on jobs, but it is averaged that over a lifetime those who attend college make about $500,000 more than those who do not. â€Å"Seven out of ten college seniors (71%) who graduated last year had student loan debt, with an average of $29,400 per borrower. From 2008 to 2012 debt at graduation †¦ increased an average rate of six percent each year. † (The Project of Student Debt). With all of the debts, not covered by either scholarships or financial aid, accumulated over the course of an individual’s schooling, the amount of additional money made becomes less substantial; if the tuition and fees were to decrease, the additional money made would not be as affected. The costs to attend two of the leading universities in Oregon, University of Oregon and Oregon State, for four years averages at about $88,000, and that doesn’t even include everyday personal expenses. For non-residents that price is more than doubled that of a resident student. â€Å"In 1980, it cost an  average of about $56,000 (adjusting for inflation) to attend a university for four years. This figure includes tuition, fees, and the â€Å"opportunity cost,† or income one foregoes to attend school instead of holding a job. (This figure excludes room and board: one must eat and sleep whether she is in college or not. ) In 2010, four years of college cost more than $82,000, a nearly 50 percent increase over that 30-year period. †(Brookings Institute). Sure there are many scholarships and financial aid a student is able to apply for, but with so many students applying for such scholarships, you’re chances of receiving them become slimmer. A lot of scholarships also do not benefit students as a whole and either target minorities, athletes, or financial aid students. Community college is also a viable option for many, but is often looked down upon. You don’t often hear a high school student say â€Å"I want to go to a community college† or â€Å"I can’t wait to go to a community college† with loads of enthusiasm. Not only do students and their families look down upon going to a community college, but teachers as well think lesser of community colleges and often express their opinions out loud. This makes students look at community colleges as less of a viable option and more of a last option. When applying for jobs, it also looks a lot more prestigious when it is shown that one attended a university rather than a community college. Although most colleges may not consider ways to lower the costs of college, there are many ways in which a lower tuition and overall price is possible. One direct contribution to the costs of schooling is the professor’s salary. Many college educators do not actually deserve the amount of money they make. Teachers should receive a salary that accurately reflects how affective the professor is at teaching. College fees also include unnecessary additions that are not required and could easily be taken off, such as gym memberships, recreation center memberships, and other additional bonuses that are not essential. Also, although I’m a student-athlete as well, the amount of money given away in scholarships just to play sports at that school has become a bit ridiculous. If the amount of money for scholarships went back into the school directly, the cost of tuition would decrease, and the need for those said scholarships would decrease as well. It is apparent that student athletes are held to a higher regard than other students. Often, you see students that are all-state athletes that get decent grades receive more money and â€Å"special treatment† in comparison to a student that does not do related extra-curricular activities, yet gets exceedingly high grades. This is not fair in any way; the elimination or decrease of athletic scholarships given out would eliminate the inequality commonly displayed throughout colleges. College tuition is at an outrageous high right now and is not showing many signs of decreasing. The costs of college and sending a student off to college have become much of a burden for many families across America. With how necessary getting a college education is considered, the cost of it all should shift to a more suitable price. The shift would be very difficult to achieve, and would be a very long process, but I do believe it is possible, not only for my generation, but the next several generations of students on the path to attend college.
