What are the three categories of sedimentary rocks?

The three categories of sedimentary rocks are clastic, chemical, and organic. Clastic rocks form from the accumulation of weathered rock fragments, chemical rocks form from the precipitation of minerals from water, and organic rocks form from the remains of living organisms.

What are the two main types of sedimentary rocks?

The two main types of sedimentary rocks are clastic (detrital) rocks, which are made of pre-existing rock fragments cemented together, and chemical rocks, which form from minerals that precipitate out of solution.

What type of rock is clastic and non-clastic?

Clastic sediments are sediments that have particles or pieces of rock (clasts) in them. The clasts can be of igneous, metamorphic or sedimentary rock. Non-clastic sediments are made up of dissolved minerals or organic matter.


How are non clastic rocks formed?

Non-clastic rocks are formed through chemical and organic processes. Chemical rocks like limestone are formed when minerals in water precipitate out and accumulate. Organic rocks like coal are formed from the remains of plants and animals that are buried and compacted over time. These processes occur without the transportation and deposition of sediments like in clastic rocks.


Difference between clastic rocks and non-clastic rocks?

Clastic rocks are sedimentary rocks consisting of bits and pieces of other rocks created by physical/mechanical weathering. Non-clastic are also sedimentary rocks; however are absent bits and pieces of other rocks and are formed through chemical processes (e.g. hydrolysis, evaporation, precipitation, oxidation) or form out of organic material (e.g. coal, chalk).
