उत्तर
The three types of sedimentary rocks based on their formation are:
- Mechanically formed sedimentary rocks (clastic rocks) - formed by accumulation and compaction of sediments (e.g. sandstone, shale).
- Organically formed sedimentary rocks - formed from organic materials like remains of plants and animals (e.g. coal, limestone).
- Chemically formed sedimentary rocks - formed by precipitation of minerals from water (e.g. limestone, chert).
