Answer:
Weathering
Step-by-step explanation:
Weathering can be seen as the wearing away of the outer layer of a rock by means of chemical, mechanical or biological agents. This process makes the rock surface to be smoother, rounder, and smaller. It also leads to the formation of soil on which we plant our crops.
The various agents such as wind, water, biological action, chemical actions, break down the external layer of the rock by acting on it, releasing tiny chunks of it into the surrounding environment, or carrying the particles away (as in the case of wind and water). This leaver a smaller rock mass standing at the end of the entire process. Please note that this process does not usually happen overnight and can take several years to be noticeable.
