One will sink beneath the other creating under water volcanoes, mountains and trench (I think)
an underwater mountain
it crates underwater mountains

Basalt
oceanic: thin, dense, basaltic rock layer.continental: thick, light, granitic rock layer.
Both oceanic and continental crusts consist primarily of igneous rock although they both contain some sedimentary rock. Oceanic crust is composed mainly of basaltic rock, while continental crust is composed of granitic rock.
Crustal shortening is the reduction of the size of the Earth's crust through tectonic activities such as those found at a convergent plate boundary. When an oceanic crust collides with a continental crust, the denser oceanic crust subducts beneath the continental crust. This causes the oceanic crust to be subducted back into the mantle and melt, reducing the size of the crust. When two continental crusts collide and neither subducts, the material is being pushed up towards Earth's surface, resulting in mountains like Mount Everest. This causes the crusts to reduce in size.
There is actually a difference between the thickness of the two. The fact is, however, that actual variance of the Earth's crust is larger than the variance between the continental and oceanic crusts. However, here is the data- The Earth's crust is comprised of layers- the continental crusts are between 35-70 km thick while the oceanic crusts are between 5-10 km thick
oceanic and the continental crust
Basalt
The collision of two oceanic crusts causes the formation of an island arc as one is forced to move over the other.
The lithosphere is composed of the oceanic and continental crusts.
Yes, it is.
continental is more buoyant
A conversion boundary is a place where 2 tectonic plates are mving toward each other. There are 3 types of convergent boundaries OCEANIC CRUST-OCEANIC CRUST OCEANIC CRUST-CONTINENTAL CRUST CONTINENTAL CRUST-CONTINENTAL CRUST They are classified according to their crust
The rocks that makes up the oceanic crusts, are very dark, relatively thin and highly dense.
Near ocean ridges such as the Atlantic ridge
