where are the thickest sedimentary deposits found
These particles accumulate on the ocean floor and may eventualy be consolidated to form the soft sedimentary rock called chalk. B. The thickest accumulations of sediments in the world are in the oceans. All but 8% of the world's sediment is in the ocean in piles up to 9 km thick.The thickest accumulation are on the continental slopes and rises.. Besides their origin, sediments also differ as to texture (Texture-the size, shape and sorting of grains in the sediment), color, and composition. We will also talk about these aspects of marine sediments and finish up with a discussion of the distribution of sediments in the sea. II.
