The oceanic crust subducts beneath the continental crust due to its higher density. Oceanic crust is basaltic and has a specific gravity of 3.3. Continental crust is granitic and has an average specific gravity of 2.9.

What are the three different types of convergent plat boundaries?

The three different types of convergent plate boundaries are oceanic-continental, oceanic-oceanic, and continental-continental. In an oceanic-continental boundary, the denser oceanic plate subducts beneath the less dense continental plate. In an oceanic-oceanic boundary, one oceanic plate subducts beneath another. In a continental-continental boundary, the plates collide and uplift, forming mountain ranges.


What occurs when dense oceanic plates collide with continental plate?

The oceanic plate subducts under the continental because it is denser. The Andes are being formed in this way and the Himalayas started that way also.

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.


How is the lava formed insind a volcano?

When an oceanic plate and a continental plate collide, it forms a volcano. The oceanic plate subducts underneath the continental plate. As the oceanic plate slides underneath, a magma chamber is formed. This magma chamber is what feeds the volcano.


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 plate always subducts?

The oceanic plate always subducts because it is denser than the continental plate. This process occurs at convergent boundaries where two tectonic plates collide, leading to one plate being forced beneath the other and into the mantle.


When the ocean floor collides with a crustal plate what happens?

it subducts underneath the crustal plate


What is continental-continental subduction?

the oceanic plate is more dense and subducts, or goes below, the continental plate.


What is a oceanic continental convergent?

These are zones/areas where two lithospheric plates, involving an oceanic and a continental plate collide.


What 3 collisions occur at a convergent boundary?

At a convergent boundary, three types of collisions can occur: oceanic-oceanic, oceanic-continental, and continental-continental. In an oceanic-oceanic collision, one oceanic plate subducts beneath the other, forming a deep ocean trench. In an oceanic-continental collision, an oceanic plate subducts beneath a continental plate, creating volcanic arcs and mountain ranges. In a continental-continental collision, both continental plates crumple and fold, forming high mountain ranges.


Differences between oceanic-oceanic and oceanic-continental subduction boundary?

In an oceanic-oceanic subduction boundary, one oceanic plate subducts beneath another oceanic plate. This process can result in volcanic island arcs being formed. In an oceanic-continental subduction boundary, an oceanic plate subducts beneath a continental plate. This can lead to the formation of volcanic mountain ranges on the continental plate.
