Explanation / Answer
1. The process of sediment becoming a sedimentary rock is called lithification. The sediments become compact and cemented by removing all their fluids under pressure. Besides, the porosity is also reduced. The answer is option D.
2. When the original material is replaced by other substances, it's called cast. Cast is the 3D structure formed by the replacement of the original matter. Mold is the hollow trace left by the organism, which may be later filled up by other material.The answer is option D.
3. Biochemical sedimentary rocks result from the accumulation of parts of organisms like the snail or clams. It forms fro the discarded parts of the dead organisms. For example, limestones, coal, diatoms and cherts form biochemical sedimentary rock.The answer is option A.
4. Clastic or detrital sediments form from the mechanical erosion and weathering of other rocks. They are classified on the basis of grain size, matrix and cement. The answer is option D.
