Explain how the biosphere interacts with the geosphere

The Geosphere interacts and affects other earth spheres in different forms. For instance, during a volcanoes (an event that occurs in the Geosphere) large particles of matter is emitted into the atmosphere.  

These particles serve as nuclei for the formation of water droplets (Hydrosphere).  

Rainfall (Hydrosphere) often increases after a volcanic eruption, which stimulates plant growth (Biosphere). 

The Particles of matter in the air (Atmosphere) falls out, killing plants (Biosphere), but at the same time enriches the soil (Geosphere) and thereby stimulating plant growth (Biosphere).

Thus this process goes on and on in a cycles and is often referred to as Earth System.

idk but if i had to take an educated guess i’d say a c d
