Detailed explanation-1: -Clastic sediment is sediment consisting of fragments of rock, transported from elsewhere and redeposited to form another rock. Clasts are individual grains that make up the sediments.
Detailed explanation-2: -happens when sediments are deeply buried, placing them under pressure because of the weight of overlying layers. This squashes the grains together more tightly.
Detailed explanation-3: -Clastic sedimentary rocks are the group of rocks most people think of when they think of sedimentary rocks. Clastic sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped.
Detailed explanation-4: -Texture: Sedimentary rocks may have clastic (detrital) or non-clastic texture. Clastic sedimentary rocks are composed of grains, fragments of pre-existing rocks that have been packed together with spaces (pores) between grains.
Detailed explanation-5: -Clastic rocks are defined as being composed of consolidated sediments formed by the accumulation of fragments derived from preexisting rocks and transported as separate particles to their places of deposition by purely mechanical agents.
