Answer:
Rocks can be simply defined as the aggregates of various minerals, and these broken rock fragments and mineral grains are formed from the weathering of rocks. Weathering refers to the breakdown of rocks due to the occurrence of various geological processes that are initiated by the agents such as wind, water and ice.
The weathering process leads to the formation of sediments of variable size and shape, and these are such as pebbles, sand, silt and clay particles.
