Answers
Explanation:
1.These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air).
2.The major importance of the hydrosphere is that water sustains various life forms and plays an important role in ecosystems and regulating the atmosphere. Hydrosphere covers all water present on the Earth's surface.
3.These layers are the troposphere, stratosphere, mesosphere and thermosphere.
4.The lithosphere is the solid, outer part of the Earth.
5.landforms can be categorized into Mountains, Plateaus, and Plains.
6.Lithosphere provide us forests, grasslands for grazing land for agriculture and human settlements and also rich source of minerals.
7.Nitrogen and Oxygen are the two main gases of..
8.It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.
