3. what changes take place during chemical weathering?

a. rock fragments are combined into larger pieces.

b. the mineralogy of previously existing rocks changes.

c. minerals crystallize as water evaporates.

Option B.

Explanation:

The mineralogy of previously existing rocks changes, is the right answer.

Chemical weathering is generated by rainwater responding with the mineral fragments in rocks to produce new crystals and water-soluble salts. These reflections transpire expressly when the water is imperceptibly acidic.

These chemical processes require water, and transpire more immediately at higher warmth, so hot, humid atmospheres are best. Chemical weathering (particularly oxidation and hydrolysis) is the initial stage in the creation of soils. During chemical weathering, the mineralogy of previously existing rocks changes.

i do not know the answer bro
