Question

Mechanical weathering is also known as____________

Answer 1

Mechanical weathering is also known as physical weathering. Weathering is often divided into the processes of mechanical weathering and chemical weathering.

Explanation

• Physical or mechanical weathering processes are influenced by applied forces. Physical weathering happens when rocks are fragmented into minor fragments while ensuring no alterations in their chemical makeup.
• Rocks are also fragmented by mechanical force. This procedure is called mechanical weathering. Because of the frequent variations in temperature, rocks begin to contract and expand. This action results in the breakdown of rocks. It is also caused by the roots of plants.

Hence mechanical weathering is called physical weathering.
