Using appropiate examples,
examine four relationships among the spheres of the earth

biosphere

atmosphere

lithosphere

hydrosphere

Explanation:

These spheres are closely connected. For example, many birds (biosphere) fly through the air (atmosphere), while water (hydrosphere) often flows through the soil (lithosphere). In fact, the spheres are so closely connected that a change in one sphere often results in a change in one or more of the other spheres.
