When two plates collide what determines which plate comes out on top?
The density of the plates and the angle of the collision can determine which plate comes out on top when two plates collide. The denser plate tends to sink beneath the less dense plate, while the angle of collision can influence the direction of movement. Additionally, the presence of features like oceanic crust and continental crust can also impact which plate is subducted.
What happens tectonic plates come together?
Convergent plates are two tectonic plates that are colliding as they move toward each other. There are several types of converging plate boundaries.Oceanic to oceanic plate convergence:Where an oceanic plate collides with another oceanic plate, the more dense plate subducts into the mantle. The subduction results in the partial melting of lithospheric rock above the area of the subduction, causing underwater volcanoes to form. If the volcanoes grow to reach the surface, volcanic arc islands are formed.Oceanic to continental plate convergence:Where an oceanic plate collides with a continental plate, the oceanic plate is subducted due to the fact that it is more dense, which can also cause volcanism and mountain building.Continental to continental plate convergence:Where two continental plates collide, neither subducts into the mantle, the crust is thickened, and mountain ranges are formed from the thickening and uplift.
Why do fold mountains and earthquakes occur at collision plate margin?
Here earthquakes occur because the 2 plates, continental plates, both are colliding with each other so due to friction, there are lots of movements so they collide, they cause movements on the earths crust so-earthquakes occur and because they are continental crusts they can't sink so they have to go somewhere so they move upwards so they cause fold mountains.
Why does plates sometime sink into the mantle?
Plates can sink into the mantle at subduction zones because the descending plate is denser than the underlying mantle. This happens because the oceanic crust of the descending tectonic plate is denser than the underlying mantle rock.
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.
When plates collide with continental plates does the denser ocean plate sink?
Yes, it "dives" under the continental crust and back into the mantle.
Why do oceanic plates dive underneath continental plates when they collide?
Oceanic plates are denser than continental plates due to their composition, so when they collide, the denser oceanic plate is forced to dive (subduct) beneath the less dense continental plate. This process occurs due to the difference in density between the two types of plates, leading to the oceanic plate sinking into the mantle.
What are three types of convergent boundaries?
Oceanic-continental convergence: Oceanic plates sink beneath continental plates, creating subduction zones and mountain ranges. Oceanic-oceanic convergence: When two oceanic plates collide, one plate is subducted beneath the other, leading to trench formation and volcanic island arcs. Continental-continental convergence: Two continental plates collide, resulting in the uplift of crust and the formation of mountain ranges.
What happens when oceanic and continental plates collide?
When oceanic and continental plates collide, the oceanic plate is usually forced under the continental plate in a process called subduction. This can result in the formation of mountain ranges on the continental plate and can lead to the creation of volcanic arcs. The collision can also cause earthquakes and tsunamis.
When two plates collide what determines which plate comes out on top?
The density of the plates and the angle of the collision can determine which plate comes out on top when two plates collide. The denser plate tends to sink beneath the less dense plate, while the angle of collision can influence the direction of movement. Additionally, the presence of features like oceanic crust and continental crust can also impact which plate is subducted.
When two plates collide what determines which plates comes out on top?
The more dense plate subducts (goes under) the less dense plate. For example if continental and oceanic crust collide oceanic crust will go underneath the continental.
Why are oceanic plates lower than continental plates?
Oceanic plates are denser and thinner than continental plates, which causes them to be lower in elevation. The denser oceanic plates are effectively pulled downward by gravity, causing them to sink beneath the less dense continental plates. This difference in density and thickness results in oceanic plates being lower than continental plates.
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.
What is the name of plates that wont sink?
Buoyant plates, such as those made of foam or other lightweight materials, are designed not to sink in water. These plates can float on the surface of the water due to their low density and ability to displace enough water to offset their weight.
Why do convergent oceanic plates subduct but continental plates do not usually respond in this way?
Oceanic crust is denser than continental crust, dense enough to sink into the mantle. Continental crust is not dense enough to do this.
Where does subdution occur?
Subduction (I believe that's what you meant) occurs at CONVERGENT boundaries, where two plates collide and the less dense one remains and the denser one sinks. An example of subduction is two oceanic plates colliding. Oceanic plates contain mainly basalt, which is dense. The oceanic plate closer to a heat source (hot spot, volcano) would remain in place while the denser plate sinks (cold water is denser than hot water so it sinks) below the other. When an oceanic plate and a continental plate collide, the oceanic plate sinks because granite (what continental plates are composed of mainly) is less dense than basalt, therefore the oceanic plate would sink. However, when two continental plates collide, because both plates are made of granite and are not very dense, they push and shape the land into mountains.
How do the mountains that form along an oceanic-oceanic convergent boundary differ from those associated with an oceanic continental convergent boundary?
the oceanic plates are denser than continental plates, therefore, when oceanic plates and continental plates converge, the oceanic will go under the continental plates. But when two oceanic converge either both will rise to form moutains, or both will sink and cause a trench.
