Question

which is true of oxidation? 1. It's a mechanical process. 2. No change occurs in the makeup of rock. 3. Rock parts weather at different rates. 4. Water enters cracks in water

Answer 1

Oxidation is a type of chemical weathering where oxygen in the air reacts with substances, like iron, to form new products such as rust, resulting in the differential weathering of rock parts.

Step-by-step explanation:

The true statement about oxidation is that rock parts weather at different rates. This reflects the understanding that oxidation is a chemical weathering process in which atmospheric oxygen reacts chemically with substances like iron (Fe) in the presence of water, causing them to change compositionally into new substances such as rust (Fe2O3). This process involves a chemical change, where new substances are formed, signifying that it's not a merely mechanical process, and there is indeed a change in the makeup of the rock. Various factors, like the presence of water and oxygen, affect the rate of this weathering process.
