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 the characteristic of the oceanic crust?
The rocks that makes up the oceanic crusts, are very dark, relatively thin and highly dense.
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 two crusts make up the Earth's crust?
Continental crust and Oceanic crust.
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
Both the oceanic and continental crusts are partially composed of this material?
Igneous and sedimentary rock. Or basalt.
