True!
As measured by its thickness from upper boundary to lower boundary in a downward direction, the mantle is the thickest layer of the Earth.
Volcanoes are common on this type of plate boundary
When plates move towards each other it is called a convergent boundary. The two types of plates converging depends on what happens. When it is oceanic/oceanic, both plates subduct (go downward), leading to the creating of trenches found at the depths of the ocean. When an oceanic plate converges with a continental plate, the more dense oceanic plate subducts under the continental plate, again creating trenches, and also leading to the destruction of the ocean floor. When continental plates converge, they tend to smash up and rise, creating mountains. When plates move apart, it is called a divergent boundary. When oceanic plates move apart, magma rises, cools, and solidifies to create new ocean floor. This, along with continental/oceanic convergence, accounts for seafloor spreading. When two continental plates diverge, the area left between them slowly turns into an ocean. For an example of this type of ocean, look at the Red Sea.
They are experiencing isostatic rebound, a rise in elevation due to the release of downward pressure from the exited ice.
The oceanic plate is made of denser (and thinner) rock than the continental crust, so the oceanic plate gets subducted (pushed underneath) where it descends and gets melted by geothermal heat.
TRUE
Yes, the continental slope drops downward to the edge of the continent at which point it plummets down for the depth of the continental plate. It depends upon whom you speak with, but a nation's boundary is generally considered 200 miles beyond that.
A destructive plate boundary.
As measured by its thickness from upper boundary to lower boundary in a downward direction, the mantle is the thickest layer of the Earth.
Downward velocity is considered a negative. This is a true statement.
The part of a continent that dips gently downward and is underwater is called the continental shelf. When a continent drops steeply in to the ocean it is called a continental slope.
CONTINENTAL SLOPE
continental shelf
continental slope
The continental shelf
The answer is: B. Continental slope.
The continental shelf is an extension of the cotton, only beneath water. The continental slope begins beyond the shelf and slopes downward.
