When two oceanic plates meet witch plate gets subducted and why?
When two oceanic plates meet, which plate gets subducted and why
Why does oceanic lithosphere sink at subduction but not at mid ocean ridges?
oceanic lithosphere sinks at subduction zones but not at mid ocean ridges because at subduction zones the oceanic lithosphere is subducted, or sinks, under another plate. Oceanic Lithosphere sinks at subduction zones which are usually at convergent boundaries, but at mid-ocean ridges the plates are actually separating not coming together
The process of an oceanic plate colliding with and descending underneath a continental plate?
The oceanic crust is subducted underneath the continental crust. This process is known as subduction.
Why is an oceanic plate always subducted but not a continental plate?
Continental plates are lighter (less dense) than oceanic plates.
What is a region where oceanic plates sink down into the asthenosphere?
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.
Why are oceanic plates lower than continental plates?
Because continental plates are denser than oceanic. That is why oceanic and continental plates cause subduction zones.
When an oceanic plate collides with a continental plate which plate is subducted?
When an oceanic plate and a continental plate collide, the oceanic plate is always subducted. Oceanic plates are denser than continental plates, and they have a higher iron content. Since they are denser, oceanic plates always sink below the continental plate in the event of a collision.
Why does oceanic lithosphere sink at subduction zones but not at mid ocean ridges?
oceanic lithosphere sinks at subduction zones but not at mid ocean ridges because at subduction zones the oceanic lithosphere is subducted, or sinks, under another plate. Oceanic Lithosphere sinks at subduction zones which are usually at convergent boundaries, but at mid-ocean ridges the plates are actually separating not coming together
What happens in oceanic oceanic convergent boundary?
Either plates gets subducted which is usually the older plate.
Zones or places where the seafloor is forced under continental plates?
Subduction of oceanic plates under continental plates occurs at convergent plate boundaries, where the plates are moving toward each other. When an oceanic plate meets a continental plate, it is usually the one subducted, due to its greater density. The Pacific "Ring of Fire", particularly east to south east Asia and the west coast of South America, is the result of oceanic plate subduction, and hence there is a high number of earthquakes and volcanism in the area.
What directions do plates move in relation to trenches?
Trenches occur in subduction zones, so one plate (usually oceanic because it is more dense) is subducted beneath the other plate, so the plates are moving towards each other
What forms where two oceanic plates collide?
subduction zone
