Explanation:
Something must move a distance for work to be done.
Explanation:
Recrystallization: contact pressure causing grains to "fuse" together
Cementation
: precipitation of bonding agents between grains
Compaction
: increase in density due to weight of overburden
Lithification is the process by which sediments are converted into sedimentary rocks. During this process, recrystallication, compaction and cementation of mineral grains occur.
The process starts with the compaction of sediments. The over burden weight of new sediments in the basin adds to the one originally deposited. This compresses the sediment. The volume of reduced and the density increases.
Recrystallization follows suit as the contact pressure of grains makes them fuse together. It is more like reworking of sediments. In this process, cementing materials can precipitate and cause sediments to be more fused together.
This is why most sediment are made up of clasts in a matrix of cementing materials.
