Typed of sedimentary rock

There are three main types of sedimentary rocks:

1. Clastic Sedimentary Rocks: These are formed from the accumulation and compaction of fragments (clasts) of pre-existing rocks and minerals. Examples include sandstone, shale, and conglomerate.
2. Chemical Sedimentary Rocks: These form when minerals precipitate out of a solution, such as seawater or lake water. Examples include rock salt (halite), gypsum, and some types of limestone formed by direct precipitation.
3. Organic (Biochemical) Sedimentary Rocks: These form from the accumulation of organic material, such as plant or animal remains. Examples include coal (from plant matter) and chalk (from marine organisms' shells).
