Oceanic crust is denser than continental crust because it is composed of mafic rocks like basalt, whereas continental crust is made of felsic rocks like granite. This density difference causes the oceanic crust to subduct under the less dense continental crust when they collide at convergent plate boundaries.

What is continental and oceanic crust?
Continental crust is the thicker, less dense, and older type of crust found beneath continents, primarily composed of granite and sedimentary rock. Oceanic crust is the thinner, more dense, and younger type of crust located beneath oceans, primarily composed of basalt. The boundary between continental and oceanic crust is known as the continental-oceanic crust boundary.
Which is an example of a terrane?
The Franciscan terrane in California is an example of a terrane. It is a complex geologic region characterized by a diverse assemblage of rocks that were accreted to the North American continent during the Mesozoic era.
Oceanic crust slides under continental crust during subduction because oceanic crust is .?
denser and thinner than continental crust.
What happens when a plate of oceanic crust collides with a plate of the continental crust and why does this happen?
When oceanic crust collides with continental crust, the denser oceanic crust is forced beneath the continental crust in a process called subduction. This happens because oceanic crust is heavier, colder, and more dense than continental crust, making it susceptible to being subducted under the lighter continental crust. This collision can result in the formation of mountain ranges, volcanic arcs, and deep ocean trenches.
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 does continental oceanic collison mean?
is means under the oceanic crust the tectonicplate collide

What is oceanic-oceanic subduction?
Oceanic crust sinking under a plate with continental crust
How do the oceanic and continental crust differ?
Because the oceanic crust is under water in the ocean and a continental crust is land such as the continents
What is oceanic and oceanic?
The continental crust is the land. The oceanic is under the ocean.
What occures when a continental and oceanic plate collide?
At some convergent boundaries, an oceanic plate collides with acontinental plate. Oceanic crust tends to be denser and thinner thancontinentalcrust, so the denser oceanic crust gets bent and pulled under, or subducted, beneath the lighter and thicker continental crust. This forms what is called a subduction zone.

The Franciscan terrane in California is an example of a terrane. It is a complex geologic region characterized by a diverse assemblage of rocks that were accreted to the North American continent during the Mesozoic era.
Oceanic crust slides under continental crust during subduction because oceanic crust is?
denser
Oceanic crust slides under continental crust during subduction because oceanic crust is .?
denser and thinner than continental crust.
What is meant by continental crust and oceanic crust?
Continental crust is the thick, less dense outer layer of Earth's surface that forms the continents. It consists mainly of granite rocks. Oceanic crust is the thinner, denser outer layer of Earth's surface that underlies the ocean basins. It is mainly composed of basalt rocks.

What do one oceanic and one continental crust produce when the oceanic crust is subducted under the continental one?
A trench and a strata volcano.
