Ocean growth is smaller when compared to tropical rainforest development. Solar heating and amount of heat absorbed by the earth. The total solar energy absorbed by Earth's atmosphere, oceans and land masses is approximately 3,850,000 exajoules (EJ) per year. Solar thermal energy is a technology for harnessing solar energy for thermal energy (heat). Keystone and indicator factors. A keystone species is a species that has a disproportionate effect on its environment relative to its biomass. Such species affect many other organisms in an ecosystem and help to determine the types and numbers of various other species in a community. Indicator species - presence indicates the presence of a set of other species and whose absence indicates the lack of that entire set of species; Desertification the causes and impact. Desertification is the extreme deterioration of land in arid and dry sub-humid areas due to loss of vegetation and soil moisture. Desertification results chiefly from man-made activities and influenced by climatic variations. It is principally caused by overgrazing, overdrafting of groundwater and diversion of water from rivers for human consumption and industrial use, all of these processes are fundamentally driven by overpopulation. Poverty is strongly linked to areas of desertification. Population and community – what do they mean when they differ? Population ecology is a major sub-field of ecology that deals with the dynamics of species populations and how these populations interact with the environment. In ecology, a community is an assemblage of two or more populations of different species occupying the same geographical area. Species interact in various ways:

competition, predation, parasitism, mutualism, commensalism, etc. The organization of a biological community with respect to ecological interactions is referred to as community structure The term for sinking of land due to too much groundwater. Subsidence (or the sinking of) (also I think sink holes apply here.) Know that Australia is planning to plant a million trees by the year "2000". Know which country does not have government supported “anti-birth” program. Mexico. Know why tropical rainforest soil isn’t suitable for planting crops. The soil is very thin, has poor quality, and is low fertility. Know what happens after global warming Answer..higher sea levels, different crop zones etc. Know about Ogallala Aquifer The Ogallala Aquifer, also known as the High Plains Aquifer, is a vast yet shallow underground water table aquifer located beneath the Great Plains in the United States. An aquifer is a groundwater storage reservoir in the water cycle. While groundwater is a renewable source, reserves replenish relatively slowly. Know what ambient temperature means. Ambient temperature simply means "the temperature of the surroundings". The ambient temperature is a non-specific phrase used to describe the outside temperature.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
