Most notable is the so-called 'Ring of Fire', an area encircling the Pacific Ocean where oceanic crustal plates are subducting under continental plates and less dense oceanic plates.
What else can I help you with?
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.
Makes up the asthenosphere?
the mantel makes up the asthenosphere
How far below the earth's surface is the asthenosphere?
The asthenosphere begins at around 100-150 km depth in the Earth. This is below the lithosphere, which consists of the crust and the uppermost mantle (the plates in plate tectonics).The asthenosphere is in the mantle, but it is still unclear how much of the mantle (which goes down to a depth of ~2900 km) is actually part of the asthenosphere.
If the asthenosphere cooled and stopped flowing how would you expect the movement of tectonic plates in the lithosphere to change Tectonic plates would?
If the asthenosphere stopped flowing due to cooling, tectonic plate movement in the lithosphere would likely slow down or even halt. The asthenosphere's convection currents drive the movement of tectonic plates by dragging them along as they flow. Without this driving force, the movement of tectonic plates would be significantly impacted, leading to reduced or stagnant plate motion.
What explains the observation that when a continental and oceanic plate collide the oceanic plate dives down under the continental plate?
This phenomenon, known as subduction, occurs because oceanic plates are denser and thinner than continental plates. When the two plates collide, the denser oceanic plate is forced beneath the less dense continental plate due to gravitational pull. This process results in the oceanic plate descending into the mantle, leading to the formation of deep ocean trenches and volcanic arcs.
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
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 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.
A is where an oceanic plate slides down into the asthenosphere?
A is called a subduction zone, where an oceanic plate converges with another tectonic plate, typically a continental plate, and is forced down into the asthenosphere. This process can lead to the formation of deep ocean trenches and volcanic arcs. The intense pressure and heat in the asthenosphere can cause the subducting plate to partially melt, contributing to magma formation and volcanic activity. Subduction zones are key areas for understanding plate tectonics and associated geological phenomena.
