Answer:
faults can cause sudden earthquakes when the tension of the tectonic plates build up and then releases
The appropriate answer is B. Chains of volcanoes along ocean coastlines. The theory of plate tectonics states that the earth's crust is divided into plates that float on the semi-molten mantle below. Plates can converge, diverge or slide past each other. Chains of volcanoes along coastlines are evidence of plates converging with one plate subducting beneath the other. The subducting plate will melt producing magma which is lighter than surrounding rock and so will force its way through cracks and fissures in the surface. Once magma reaches the earth's surface, volcanoes are formed.
The correct answer is - Habitat.
The shallow and brackish water in an estuary represents the habitat that the estuary is providing for the living organisms in it.
The reason why this is a description of the habitat of the estuary is that the description provides information about the living conditions in it. It tells us what kind of waters there, and the water is the basis for the existence of the marine life. By the description, it also can tell us what kind of a marine life can be expected to live there, as certain species are well adapted for this kind of habitat, while others are not.
There are about 169 volcanoes in the continental United States
