Their main differences are in thickness, composition, density and age.
- Oceanic crust is thinner (5-10 km thick) than continental crust (20-70 km thick).
- Oceanic crust is composed of minerals that have higher concentrations of iron and magnesium (Mafic minerals) than those of the continental crust (which is richer in aluminum and silica - Felsic minerals).
- The rocks that make up the oceanic crust are typically more dense (3300 kg/m3) than those that make up the continental crust (2700 kg/m3).
- Oceanic crust is as a rule much younger than continental crust; the oldest oceanic crust is rarely over 200 million years in age, whereas the continental crust can exceed 3 billion years in age.

What two types of plates does convergent boundaries involve?
There are two types of crust on Earth: oceanic and continental. A convergent plate boundary can involve two plates of oceanic crust, two of continental crust, or one of each.
What are the two types of crust that make up the outermost layer of the earth?
Continental Crust And Oceanic Crust.
What are the two types of crust and which rocks make up each crust?
there are two types of crust such as the oceanic crust and the continental crust, the oceanic crust is thinner and more dense than the continental crust and is constantly being recycled via subduction upon collisions with Continental crust, and creating at mid-ocean ridges. x
What two types of deformation in Earth's crust?
orogeny and epeirogeny
What is meant by continental crust and oceanic crust?
They are two different types of crust. Continental crust is heavier than Oceanic crust, so when the two collide, the Continental crust 'subducts' under the Oceanic Crust. 'Crust' referring to the tectonic plates, the surface of the Earth we stand on.
What two types of crust are involved at this type of convergent boundary?
The two types of Crust is the Continental Crust and the Oceanic Crust.
What types of crust can be found in the lithosphere?
There are two types of crust, there is the oceanic and the continental crust.
What two tyoes of crust?
There are two types of Crust : 1. Continental Crust, 2. Oceanic Crust.
What are the two types of crust that makes up the continents and ocean?
The two types of crust that make up the continents and ocean are the continental crust and the oceanic crust.
What are the two types of crust on the earth?
There are two types of crust, and they are the oceanic crust and the continental crust. Oceanic crust is thinner yet more dense than continental crust, and continental crust is on average older than oceanic crust :)
What are two different types of lithospheres?
Oceanic Crust & Continental Crust

What are two kind of crust that a tectonic plate may contain?
The two types of crust may be called continental crust and oceanic crust. They can also be called granitic and basaltic crust respectively.
