Answer 1

TOPSOIL


SUBSOIL


PARENT ROCK


BEDROCK

Answer 2

1. Horizon A or Topsoil

It is also called the humus layer, which is rich in organic material. 

2. Horizon B or Subsoil

Just below the topsoil lies another layer called subsoil or horizon-B. It is comparatively harder and compact than topsoil.

3. Bedrock or Horizon C

Bedrock is also known as parent rock and lies just below the subsoil. It contains no organic matter and made up of stones and rocks, so it is very hard. 

Hope this will help you ^_^
