What is a region where oceanic plates sink down into the asthenosphere?
A subduction zone is a region where oceanic plates sink down into the asthenosphere beneath another plate, such as at convergent plate boundaries. This process can lead to the formation of deep oceanic trenches, volcanic arcs, and earthquakes.
A region where oceanic plates sink down?
Subduction Zone
What is A region where oceanic plates sink down into the lithosphere?
A subduction zone.
About the asthenosphere?
The asthenosphere has the ability to slow down seismic waves. Is not made up of earths plates that would be the lithosphere.
What are the oceanic plates pushed down in the upper mantle in?
Subduction Zones.

What are tectonicsplates?
Tectonic plates.Tectonic plates are plates underneath Earth's surface that move very slowly. There are oceanic and continental plates. Of course, oceanic plates are plates under the ocean, and continental plates are plates underneath ground, or continents. Each of the plates carry the things above them, land or ocean. When two continental or oceanic plates collide, it causes a fold in Earth's surface, and an earthquake. Now, when a continental plate draws near and nearly collides with an oceanic plate, something called subduction occurs. Subduction is basically when the oceanic plate dips down below the continental plate, causing a trench.
What are the two differences between the continental crust and the oceanic crust?
The oceanic crust consists of heavier rock, mostly Basalt, so that if a oceanic plate collides with a continental plate the oceanic plate will be forced down below the continental plate, forming island arcs.continental plates are thicker than oceanic plates.
When oceanic plates drop back away from continental plates what happens?
A few things could happen. The separation could leave a gap in the two plates, and if the plate is deep enough, magma could rise and cool. Also depending on how high the magma rises, it could either add to the land or add to the ocean floor, most likely the ocean floor. The continental plate may also continue to move with the oceanic plate, as the crust is resting on the wobbly viscous asthenosphere.
What happens if an oceanic to oceanic happens?
When an oceanic to oceanic happens, two oceanic plates converge and one of the plates subducts into a trench. The subducted plate sinks down into the mantle and begins to melt. Molten rock from the plate rises toward the surface and forms a chain of volcanic islands, also called a volcanic island arc, behind the trench in the ocean.
Why does the continental crust go father down into the mantle than the oceanic crust?
Continental crust, on average, is much thicker than oceanic crust. Because of the principles of isostacy and buoyancy, the continental crust will protrude more deeply into the asthenosphere than oceanic crust.
Makes up the asthenosphere?
the mantel makes up the asthenosphere
