The Pacific plate is mostly oceanic lithosphere while the North American plate is mostly continental lithosphere.
As odd as it is to think of things this way, continental lithosphere is more buoyant than oceanic lithosphere. The oceanic lithosphere is more dense.
An island arc forms.
Oceanic lithosphere is dense enough to be forced down into the mantle. Continental lithosphere is not.
There are two types of lithosphere: the oceanic lithosphere and the continental lithosphere. The oceanic lithosphere exists in the ocean basins while the continental lithosphere exists in the continental crust.
New oceanic lithosphere forms as a result of continental drift.
No continental lithosphere contains more felsic rocks than oceanic lithosphere.
Earth contains a lithosphere that contains the crust and the mantle. There are two types of lithospheres on earth which are the oceanic and the continental.
As odd as it is to think of things this way, continental lithosphere is more buoyant than oceanic lithosphere. The oceanic lithosphere is more dense.

The lithosphere is composed of crust and hard upper mantle. The oceanic lithosphere would be hard upper mantle and basaltic oceanic crust.

Oceanic lithosphere is dense enough to be forced down into the mantle. Continental lithosphere is not.
The density of the continental (granitic) lithosphere is lower than oceanic (basaltic) lithosphere. Consequently, due to buoyancy, the continental crust rides above the oceanic lithosphere and thus is not subducted. However, it is thought that pieces of the continental lithosphere break off and are subducted along with the oceanic lithosphere.
There are two types of lithosphere: the oceanic lithosphere and the continental lithosphere. The oceanic lithosphere exists in the ocean basins while the continental lithosphere exists in the continental crust.
The two layers of the lithosphere is made up of the oceanic lithosphere and continental lithosphere. The oceanic lithosphere is associated with oceanic crust and the ocean basins. The continental lithosphere is associated with the continental crust.
