After earth formed, the emerging biosphere had several effects on earth’s lithosphere. for example, rocks and minerals showed evidence of a. cobustion b. oxidation c. fossilization d. respiration caused by the presence of oxygen in air. in a second example, a. minerals b. organisms c. carbon dioxide d. sunlight actually created new rock after being dissolved in water or buried underground.

Rocks and minerals showed evidence of OXIDATION. Moreover, ORGANISMS actually created new rock after being dissolved in water or buried underground.

Oxidation is a natural process in which electrons are removed from a molecule during a given chemical reaction.

In conclusion, rocks and minerals showed evidence of OXIDATION. Moreover, ORGANISMS actually created new rock after being dissolved in water or buried underground.

The answer is; B

Initially, the earth’s atmosphere was mainly filled with carbon dioxide and methane. However, with the evolution of photosynthetic organisms, the composition of the atmosphere changed to be mainly oxygen. This geological time is referred to as the great oxygenation event. The high oxygen levels resulted in oxidation of most the upper lithosphere.  

The answer is; B

During this time, the organism on earth began to evolve and live on land. Therefore these geologic events are marked by fossilized of dead primitive organisms such as archaebacteria within the early rocks

it would be a gas formation
