∙ 14y agoYes, the continental slope descends steeply from the continental shelf into the deep ocean floor. It marks the boundary between the continental crust and the oceanic crust.
Oceanic plates are denser than continental plates, so when they collide at a convergent boundary, the denser oceanic plate is forced to subduct beneath the less dense continental plate. This subduction is driven by the force of gravity pulling the denser plate downward. This process can lead to the formation of volcanic arcs and deep ocean trenches.
Volcanoes are common on this type of plate boundary
A normal fault is typically found on a divergent boundary. This type of fault occurs as the Earth's crust is being pulled apart, causing one side to move downward relative to the other.
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.
The mantle is the thickest layer of the Earth, extending from the crust to the outer core. It accounts for approximately 84% of Earth's volume and is composed of solid rock that is capable of flowing over long periods of time.
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 syncline is a downward fold in rock layers where the youngest rocks are in the center and the oldest rocks are towards the edges. It forms a U shape, with the limbs of the fold dipping towards the center.
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
A convergent plate boundary is caused by a downward convection current in the mantle. At these boundaries, tectonic plates move towards each other, resulting in subduction zones or collision zones, where one plate is forced beneath the other.
The continental shelf
The answer is: B. Continental slope.
The force pushing upward on the continental crust is isostatic rebound, caused by the buoyancy of the less dense continental crust floating on the denser mantle. The downward force is from the weight of the overlying rock and sediments, as well as tectonic forces like subduction or compression.
Oceanic plates are denser than continental plates, so when they collide at a convergent boundary, the denser oceanic plate is forced to subduct beneath the less dense continental plate. This subduction is driven by the force of gravity pulling the denser plate downward. This process can lead to the formation of volcanic arcs and deep ocean trenches.
