A region where oceanic plates sink down into the asthenosphere?
a region where oceanic plates sink down into the asthenosphere is called a subduction zone.
A region where oceanic plates sink down?
Subduction Zone
Why does oceanic lithosphere sub duct while continental lithosphere does not?
Oceanic lithosphere is dense enough to be forced down into the mantle. Continental lithosphere is not.
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.
How long is The lithosphere?
The lithosphere typically extends from the Earth's surface down to about 80-100 kilometers in depth. However, its thickness can vary depending on location, with regions of mountain ranges or oceanic ridges having thinner lithospheric plates.
What is the process called when the oceanic plates slide down the slope of lithosphere-asthenospher boundary?
The process is called "subduction." It occurs when one tectonic plate moves beneath another at a convergent boundary, where the oceanic plate is forced down into the mantle at a subduction zone. This process leads to the recycling of old oceanic crust back into the mantle.
What is the process where new oceanic lithosphere formed?
New oceanic crust is created at the mid-ocean ridges where rift volcanoes feed solidifying magma from the asthenosphere to both sides of the divergent plate boundaries. The mid-ocean ridge marks the line where heat from the Earth's interior is being carried to the surface by convection currents in the mantle. At the opposite end of the convection currents, colder, denser, and older oceanic crust is being drawn down into the asthenosphere, the birth to death of oceanic crust occurring in roughly 150 million year cycles.
What are the oceanic plates pushed down in the upper mantle in?
Subduction Zones.
What are oceanic plates pushed down in the upper mantle in?
Subduction Zones.
What iis a plate tectonics?
The theory that the lithosphere is broken down into plates that can move.
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.
