Answer:

B). Organic Material

Explanation:

Sediments are described as the collection of small particles, particularly dirt, that precipitate from a river or other body of water. It includes fragments of rock, fossils(remains of plants, as well as animals), and the minerals that move through the pace of the water in the river and deposited to a distinct place. The element that sediments do not include is 'organic material' as the only organic material found in sediments are fossils and that too in a very little amount(even less than 1%) because the organic material gets destroyed and through the forces of water during erosion and thus, they don't settle in the bottom. Thus, option B is the correct answer.

The Crust

Explanation:

Answer:

the Crust

Explanation:

Answer:

Compressional forces bend the sedimentary layers in the back-arc region downward, creating a bowl-like depression.

Explanation:

The back-arc basin is formed with the weight of one tectonic plate on top of another. This happens when a tectonic plate with a higher density protrudes over a tectonic plate of lower density causing a "sinking" of the less dense plate. This causes a spread of the posterior arch that folds to form a trench-shaped depression. This "sinking" is called subduction and allows the upper tectonic plate to defeat the mantle on the overlapping plate, causing a greater chance of magma leaking onto the surface.

When two plates sliding alongside each other forming faults that leads to earthquakes in that region.
