Which process is a form of mechanical weathering apex

Physical weathering, also known as disaggregation or mechanical weathering, refers to the category of procedures, which makes the disintegration of rocks in the absence of chemical modification. In general, the mechanical weathering takes place due to the build-up of pressure within the rocks.

However, the rocks can also get worn away by a procedure known as abrasion. Abrasion refers to the disintegration of rocks due to friction.

The abrasion is a form of mechanical weathering apex.

Explanation: Abrasion is the breakdown of rock by friction. Mechanical weathering is disintegration of rocks due to physical forces without any chemical reactions. So abrasion is process of mechanical weathering.
