Question

Name different types of sedimentary rocks.

Name the three types of sedimentary rocks based on their formation.

Answer 1

The three types of sedimentary rocks based on their formation are:

1. Mechanically formed sedimentary rocks (clastic rocks) - formed by accumulation and compaction of sediments (e.g. sandstone, shale).
2. Organically formed sedimentary rocks - formed from organic materials like remains of plants and animals (e.g. coal, limestone).
3. Chemically formed sedimentary rocks - formed by precipitation of minerals from water (e.g. limestone, chert).
