Question

which of the following best explains how microbial life affects the geosphere? (1 point) microbes cause earthquakes microbes help break down rock and contribute to soil formation microbes reduce ocean temperature microbes build underground caves

Explanation:

Earthquakes are driven by tectonic forces, not microbes. Ocean temperature regulation is tied to climate and ocean dynamics, not microbial activity. Underground caves form from water erosion, not microbes. Microbes produce acids and enzymes that break down rock, aiding soil formation, which directly impacts the geosphere.

Answer:

Microbes help break down rock and contribute to soil formation
