Due to decreased light penetration, B. THE MOUTH of the rivers and streams will have less diversity of plant life.
The decreased light penetration is brought about by the murkiness of the water due to numerous deposits of sediments. Sediments that have been collected at the water travels towards the mouth of the rivers and streams causes the water to be muddy and murky making it impossible for light to penetrate.
Answer:
A tectonic plate is moving over a mantle plume, which burns through the plate to create a chain of volcanoes.
Explanation:
For a chain of volcanic islands to form, it is necessary for the tectonic plates to move on top of a mantle plume, thus creating a "cord" of islands, forming the chain of volcanic islands.
A plume mantle is also called a hot spot and is formed by a geological thermal aanomalia, which pulls the magma from the deepest layers to the surface.
Pollution is the primary cause
