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 a continental plate and an oceanic plate collide why does the oceanic plate sink below the continental plate?
The oceanic plate is denser than the continental plate due to its composition of heavier mafic rock. This density difference causes the oceanic plate to sink below the continental plate in a process known as subduction.
When oceanic plates collide with continental plates the oceanic plate goes under the continental plate because?
The oceanic plate subduct under the continental because oceanic is made from basalt(rock) which is denser than andesite and granite(continental)
What happens to mantle rock descending oceanic crust scrapes past continental crust?
As the oceanic crust descends beneath the continental crust, the mantle rock is subjected to high pressure and temperature. This causes the mantle rock to partially melt, producing magma that can rise to the surface and form volcanoes. The interaction of the descending oceanic crust with the continental crust can also lead to earthquake activity.
When an oceanic plates collides with continental plate the oceanic plate is usually subfucted because?
When an oceanic plate collides with a continental plate, the oceanic plate is usually subducted because it is denser and thinner than the continental plate. This density difference causes the oceanic plate to sink beneath the continental plate into the mantle, forming a subduction zone. This process can lead to the formation of deep ocean trenches and volcanic arcs on the continental side. Additionally, the subduction of the oceanic plate contributes to geological activity such as earthquakes and volcanic eruptions.

Why is oceanic lithosphere subducted during and oceanic continental collision where as the continental plate is not?
Oceanic lithosphere is denser than continental lithosphere, so it is more likely to be subducted during a collision. The downward force exerted by the dense oceanic plate causes it to sink beneath the less dense continental plate. Furthermore, oceanic lithosphere is typically thinner and more malleable, making it easier to be forced beneath the continental lithosphere.
What causes an ocean trench form?
subduction of an oceanic plate under a continental plate.

How do volcanoes form were oceanic and continental plates collide?
When oceanic and continental plates collide, the denser oceanic plate subducts beneath the continental plate. This subduction causes melting of the mantle, creating magma that rises to the surface, forming volcanoes on the continental plate. The magma eventually erupts through the volcano, leading to the formation of volcanic islands or mountain ranges.
Are continental plates more buoyant than oceanic plates?
Yes, continental plates are more buoyant than oceanic plates because they are thicker and less dense. Continental plates are made up of less dense material such as granite, while oceanic plates are primarily composed of denser basaltic rock. This difference in density causes continental plates to float higher on the underlying mantle.
Are oceanic or continental crusts more buoyant?
Continental crust is more buoyant than oceanic crust because it is thicker and composed mainly of less dense rocks like granite, whereas oceanic crust is thinner and denser due to its basaltic composition. This difference in density causes continental crust to float higher on the mantle, making it more buoyant.
Why does ocenaic crust sink beneath the continental crust at a subduction boundary?
Oceanic crust is denser than continental crust due to its composition of basaltic rock and higher iron content. This density difference causes oceanic crust to sink beneath the lighter continental crust at subduction zones, creating a convergent boundary. The descending oceanic plate creates deep oceanic trenches and can trigger volcanic activity when it melts and rises to the surface.
Collision of a continental and oceanic plate causes this in the plates?
The oceanic plate is forced beneath the continental plate in a process called subduction. This collision can lead to the formation of deep oceanic trenches, volcanic arcs, and earthquakes due to the intense pressure and friction between the two plates.
