What the lithosphere made up of?
The lithosphere is composed of the oceanic and continental crusts.
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 happens when a plate Carrying oceanic crust collides with a plate carrying continental crusts?

Oceanic and Continental crusts are alike because they both shift and move and grow. They differ by there rock types. Oceanic crust is made up of dense basalt while continental crust is made up of less dense granite.
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
How are oceanic crust and continental crust alike How are they different?
Oceanic and Continental crusts are alike because they both shift and move and grow. They differ by there rock types. Oceanic crust is made up of dense basalt while continental crust is made up of less dense granite.
Is Eurasian plate an oceanic plate or a continental plate?
