B. Extrusion
Step-by-step explanation:
Extrusion process is not involved in the process of formation of sedimentary rocks. These rocks are formed by following processes -
1) weathering of preexisting rocks
2) transport of the weathering products
3) deposition of the material
4) compaction
5) cementation of the sediment to form a rock
At the point when rocks are at or close to the outside of the earth they are presented to the procedures of weathering. Sediments are deposited layer upon layer. The layers are kept evenly. As sedimentation proceeds, the prior stored residue are weighed down with an expanding overburden. They are compacted, diminishing the accessible pore space and removing a significant part of the pore-water.
