What are the 5 Earth systems?
Answers
Answer:
The five systems of Earth (geosphere, biosphere, cryosphere, hydrosphere, and atmosphere) interact to produce the environments we are familiar with
Explanation:
Answer:
There are five main systems, or spheres, on Earth. The first system, the geosphere, consists of the interior and surface of Earth, both of which are made up of rocks. The limited part of the planet that can support living things comprises the second system; these regions are referred to as the biosphere. In the third system are the areas of Earth that are covered with enormous amounts of water, called the hydrosphere. The atmosphere is the fourth system, and it is an envelope of gas that keeps the planet warm and provides oxygen for breathing and carbon dioxide for photosynthesis. Finally, there is the fifth system, which contains huge quantities of ice at the poles and elsewhere, constituting the cryosphere. All five of these enormous and complex systems interact with one another to maintain the Earth as we know it.
It is clear that all of Earth’s systems are deeply intertwined, but sometimes this connection can lead to harmful, yet unintended, consequences. One specific example of interaction between all the spheres is human fossil fuel consumption. Deposits of these fuels formed millions of years ago, when plants and animals—all part of the biosphere—died and decayed. At that point, their remains were compressed within Earth to form coal, oil, and natural gas, thus becoming part of the geosphere. Now, humans—members of the biosphere—burn these materials as fuel to release the energy they contain. The combustion byproducts, such as carbon dioxide, end up in the atmosphere. There, they contribute to global warming, changing and stressing the cryosphere, hydrosphere, and biosphere.
