Answer 2

\(\text{Organic sedimentary rocks:}\)
Organic sedimentary rocks are composed of organic matter in the form of plant fragments. We usually think of this group of rocks as coal.

\(\text{Chemical sedimentary rock:}\)
Evaporites are formed in this depositional environment. Salts, carbonates, and sulfates mostly. Halite, sylvite, calcite, gypsum, etc.

\(\text{Detrital sedimentary rocks:}\)
Are those for which the material has been transported as solid particles. The particles themselves may have derived from either physical weathering or chemical weathering. Sedimentation means settling from a fluid, either water or air. The texture of sedimentary rocks is described as "clastic", meaning that they are composed of discrete particles that are compacted and cemented together. An example of a non-clastic texture would be crystalline material.
