Thick accumulations of sediments and fossils in the deep ocean tend to be ___________-sized because of the low amounts of energy.

Question

Quizplus · Accepted Answer

In the deep ocean, there is very low energy and so smaller-sized sediments tend to accumulate. Clay particles are among the smallest-sized sediments, making them the most likely to accumulate in thick accumulations in the deep ocean. Cobble and gravel are larger-sized sediments, thus they are unlikely to accumulate in thick accumulations in the deep ocean. Sand is a medium-sized sediment and can be present in deep ocean sediments, but it is not the best choice for this question.
