Oceanic crust is the part of Earth's lithosphere that surfaces in the ocean basins.
Oceanic crust is primarily composed of mafic rocks, or sima, which is rich in iron and magnesium.
It is thinner than continental crust, or sial, generally less than 10 kilometers thick, however it is denser, having a mean density of about 2.9 grams per cubic centimeter.[1]

Are oceanic plates only made up of oceanic crust?
yes but oceanic crust is younger than continental crust because of deep sea trenches
What is the difference between oceanic plate and continential plate?
Oceanic plates are young and made of basalt and recent sediments. Continental plates are old and contain continental crust made of old rocks and they are usually considerably thicker than the oceanic plates
What are large blocks of crust called?
plates There are continental plates (thick and made of granite) and oceanic plates (thin and made of basalt).
Name two types of tectonic plates?
The two types of tectonic plates are continental and oceanic.
What is the main mineral that Continental and Oceanic plates are made up of?
Continental plates are composed of mainly granitic rock.

Are oceanic plates only made up of oceanic crust?

How many plates is earth's crust made of?
There are currently 14 continental and oceanic plates that make up the earth's crust.
What is the difference between oceanic plate and continential plate?
Oceanic plates are young and made of basalt and recent sediments. Continental plates are old and contain continental crust made of old rocks and they are usually considerably thicker than the oceanic plates
What are continental plates made of?
AnswerThe continental plates are made up of largely granitic rock, while the oceanic plates are largely basaltic rock. Certainly some other types of rock are included, but these are the largest contributors to the material or composition. A link is provided below for more information.
