what are the factors that support life on earth

The main components of the earth system are interconnected by flows (also known as pathways or fluxes) of energy and materials. The most important flows in the earth system are those concerned with the transfer of energy and the cycling of key materials in biogeochemical cycles.

How do Earth subsystems interact with one another?

These spheres are closely connected. For example, many birds (biosphere) fly through the air (atmosphere), while water (hydrosphere) often flows through the soil (lithosphere). … Interactions also occur among the spheres; for example, a change in the atmosphere can cause a change in the hydrosphere, and vice versa.

What is the key role that energy plays in the interaction among the four systems of the earth?

Scientists divided the planet into two main components: the biosphere and the geosphere of all life. Explanation: Energy is not a physical unit. … As these subsystems interact with the biosphere, they work together to affect climate, and also they trigger the whole geological process.
