One will sink beneath the other creating under water volcanoes, mountains and trench (I think)

What materials are oceanic and continental crusts partially composed of?
Basalt
Characteristics of oceanic and continental crusts?
oceanic: thin, dense, basaltic rock layer.continental: thick, light, granitic rock layer.
Both the oceanic and continental crusts are partially composed of what material?
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.
What is crustal shortening?
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.
How does the thickness of continental crust differ from that oceanic crust?
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
What are two kinds of crusts?
oceanic and the continental crust
What materials are oceanic and continental crusts partially composed of?
Basalt
What is oceanic oceanic collision?
The collision of two oceanic crusts causes the formation of an island arc as one is forced to move over the other.
What the lithosphere made up of?
The lithosphere is composed of the oceanic and continental crusts.
Is seafloor spreading a process that forms a new oceanic crusts?
Yes, it is.
Are oceanic or continental crusts more buoyant?
continental is more buoyant
What are convertgent boundaries?
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
What are the characteristic of the oceanic crust?
The rocks that makes up the oceanic crusts, are very dark, relatively thin and highly dense.
Where are the newest oceanic crusts located?
Near ocean ridges such as the Atlantic ridge
Characteristics of oceanic and continental crusts?

What two crusts make up the Earth's crust?
Continental crust and Oceanic crust.
