Answer :
Answer:
The mechanical weathering is defined as the breaking down of rocks physically due to the agents such wind, water and ice. In addition this, plant roots, abrasion, rainfall and temperature also plays an important role in wearing away the rocks.
When water, wind flows over the rock surfaces, it erodes the rocks and this is known as the abrasion process. The broken particles (sediments) are transported by these agents and deposited at some other place.
The rocks also undergoes deformation due to the frost wedging process, freeze and thaw method, exfoliation and some other process.
These are the processes that are responsible for mechanical weathering.
