Question

Define (1) topsoil and (ii) bedrock.​

Answer 1

Answer :-

Topsoil :-

Topsoil refers to the top layer of soil that is high in organic matter and nutrients, formed by the slow weathering of rocks and decaying organic matter over thousands of years.

Bedrock :-

Bedrock is the hard, solid rock beneath surface materials such as soil and gravel. Bedrock also underlies sand and other sediments on the ocean floor. Bedrock is consolidated rock, meaning it is solid and tightly bound. Overlying material is often unconsolidated rock, which is made up of loose particles.
