Question

Can you compare the deposition of a dense, small and round sediment to a large,
low density, medium-sized flat sediment? Support your answer with evidence from the text.

Answer 1

Answer:

Rivers, oceans, winds, and rain runoff all have the ability to carry the particles washed off of eroding rocks. Such material, called detritus, consists of fragments of rocks and minerals. When the energy of the transporting current is not strong enough to carry these particles, the particles drop out in the process of sedimentation. This type of sedimentary deposition is referred to as clastic sedimentation. Another type of sedimentary deposition occurs when material is dissolved in water, and chemically precipitates from the water. This type of sedimentation is referred to as chemical sedimentation. A third process can occur, wherein living organisms extract ions dissolved in water to make such things as shells and bones. This type of sedimentation is called biochemical sedimentation. The accumulation of plant matter, such as at the bottom of a swamp, is referred to as organic sedimentation. Thus, there are 4 major types of sedimentary rocks: Clastic Sedimentary Rocks, Chemical Sedimentary Rocks, Biochemical Sedimentary Rocks, and Organic Sedimentary Rocks.

Clastic Sediments and Sedimentary

Answer 2

Deposition of a dense, small and round sediment to a large, low density, medium-sized flat sediment can be compared as because surface area of the dense, small and round sediment is less than the large, low density, medium-sized flat sediment. As, the surface area differs the dense, small and round sediment will sink inside water, but the large, low density, medium-sized flat sediment will float on the surface of water.
