Soil is formed by weathering this is divided into 3 types:
1⃣Soil is formed by weathering of rocks means breaking down the rocks into fine particles.T his is known as physical weathering.
2⃣chemical.weathering -rocks through a change in their chemical makeup. This can happen when the minerals within rocks react with water, air or other chemicals.
3⃣biological weathering—the breakdown of rocks by living things. Burrowing animals help water and air get into rock, and plant roots can grow into cracks in the rock, making it split.
