Name four clastic sedimentary rocks and explain how these rocks form

Limestone: it can form organically from the accumulation of shell, coral,and fecal debris. It can also form chemically from the precipitation of calcium carbonate from lake or ocean water. 
Breccia: Composed of large fragments and the spaces between the fragments are filled with smaller pieces and mineral cement
Rock Salt: forms from the evaporation of ocean or saline lake waters.
Sandstone: forms from sand size weathering debris in environments where large amounts of sand can accumulate include beaches, deserts, flood plains and deltas.

Your answer is d. silli hope this ! : ) i left an explanation down below if you need it: a sill forms when hot magma squeezes between layers of rock to form a hardened sheet of rock. a sill is basically a tabular sheet intrusion between old layers of sedimentary rock, volcanic beds, or in the direction of foliation inherent in metamorphic rock. the word sill means a concordant intrusive sheet.

The correct answer is:   [b]:   "distortion" .
