Question

select the correct answer from each drop - down menu. complete the sentences about earths early biosphere. after earth formed, the emerging biosphere had several effects on earths lithosphere. for example, rocks and minerals showed evidence of caused by the presence of oxygen in air. in a second example, actually created new rock after being er or buried underground.

Explanation:

Oxidation is a chemical reaction involving oxygen. When oxygen in the air reacts with rocks and minerals, it causes oxidation. Fossilization is the process where organisms (after being buried or in water) can form fossils and also contribute to new rock formation (like coal from plant - matter fossilization).
Combustion requires a fuel, heat, and oxygen but is more of a rapid reaction (like fire) and not the main process related to rock - mineral oxygen interaction in the lithosphere as described. Respiration is a biological process in organisms to release energy and not directly related to the lithosphere - biosphere interaction in the context of rock formation from the given description.

Answer:

First blank: oxidation
Second blank: fossilization
