Define Environmental Science
is the collection of all those disciplines concerned with the physical, biological, and chemical processes and interactions of the surroundings in which organisms live.
What is global warming?
the gradual rise in the Earth's average atmospheric temperature.
What is the green house effect?
The result of this effect is that not all of the long-wave solar radiation that reaches Earth's surface is reflected back into space.
What are some common green house gases?
Carbon dioxide
ozone
methane
nitrous oxide
water vapor
carbon-based chemicals called
Chlorofluorocarbons (CFCs)
What is the Milankovich cycle?
Slow, cyclical variations in Earth's spin as well as its orbit around the sun. They affect worldwide climate patterns by minimizing or maximizing insolation, or the amount of solar radiation received at Earth's surface.
How may Milankovich cycles have been identified?
3
Define primary pollution
is the direct introduction of pollutants into the atmosphere.
Define secondary pollution
the release of chemicals that must react with other substances present in the environment in order to be destructive.
Define eutrophication
is the process by which bodies of water deteriorate after being formed.
Define Terracing
involves interrupting the natural slope of land with constructed flat areas that follow the same topographic contour around a hill or incline.
What is no-till agriculture?
no-till farming minimizing soil disturbance, and it does so by way of the following steps.
What is geothermal energy?
is heat that comes from inside the Earth.
Why is the concept of cycles so important to environmental science?
Cycles are central to may environmental processes, and they must be kept in precise balance in order to most effectively support Earth's numerous organisms.
What are some of the common cycles in nature?
Carbon and nitrogen cycles and the Milankovich cycles.
What are Milankovich cycles?
Are slow, periodic astronomical variations in Earth's spin and its orbit around the Sun. These cycles can affect worldwide climate patterns by minimizing or maximizing insolation, or the amount of solar radiation received at the Earth's surface.
What are some environmental dangers that can be traced to the use of chlorofluorocarbonds?
CFCs accelerate the process of global worming by serving as greenhouse gases. They also deplete Earth's ozone layer and therefore allow greater amounts of dangerous ultraviolet radiation to enter the atmosphere.
What is the difference between Environmental Science
Environmental Enginering
Environmentalism?
ES is the collection of all those disciplines concerned with the physical, biological, and chemical processes and interactions of the surroundings in which organisms live.
EE involves the application of scientific principles to remedy environmental problems.
E is a philosophy and/or political movement that focuses upon the protection and conservation of environmental resources.
