Identify each event as the result of mechanical weathering or chemical weathering.

Explanation:

When chemical reactions change the chemical composition of a mineral then this process is known as chemical weathering.

In chemical weathering the particle become molecularly different  from the original rock.

Chemical weathering occurs due to the process of dissolution or oxidation.

When chemical reactions does not change the chemical composition of a mineral then this process is known as mechanical weathering.

In mechanical weathering, the smaller particles molecularly remain similar to the original rock.

Mechanical weathering occurs due to the processes like frost-wedging and plant activity.
