Which one is mechanical weathering and which one is chemical weathering? explain why. Plant root growing-

Pressure release-

Dissolving-

Explanation:

An accompanying diagram is need to answer this question. Mechanical or physical weathering involves the break up of rock into smaller pieces. Mechanical weathering does not change the chemical compositionit is just broken down into smaller pieces. In frost wedging the constant freezing and thawing will break rocks into smaller pieces. This occurs in temperate mountainous regions. Salt wedging occurs at coastal areas where ocean water deposits the salt in the rocks. Peeling is also known as exfoliation and this occurs in desert regions rocks constantly contract and expand as the temperature drastically changes. Biological weathering is caused by plant roots or burrowing animals. Their actions cause rocks to be broken into smaller pieces.

The diagram that does not demonstrate any of these activities is not likely to be mechanical weathering.
