Oxidation (a type of chemical weathering)

Explanation:

Chemical weathering is defined as the process by which rocks are disintegrated into smaller particles by chemical reactions. There are different types of chemical weathering and the presence of materials i.e. acids, oxygen, water, and carbon dioxide in rocks can change the minerals found in different rocks. Oxidation is a type of chemical weathering which involves the reaction of oxygen with a substance. Oxidation is also the process that causes rusting of material. If a rock contains iron, it can also undergo oxidation (i.e. rust).

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).

answer: cellular respiration takes in food and uses it to create atp, a chemical which the cell uses for energy. usually, this process uses oxygen, and is called aerobic respiration. it has four stages known as glycolysis, link reaction, the krebs cycle, and the electron transport chain.
