What is the difference of continental crust and oceanic crust?
Two differences are that the oceanic crust is more dense than continental, and continental crust is composed mostly of granite, while oceanic is mostly basalt
How do continental crust differ from oceanic?
Continental crust is predominantly composed mostly of rock of a granitic composition, higher in silica and aluminum, with layers of sedimentary rock above. Oceanic crust is predominantly basaltic (higher in iron and magnesium), darker, thinner, more dense, and formed from rapid cooling of lava.
Most of the continental crust and oceanic crust is composed of what?
Igneous rock.
How are oceanic crust and continental crust different?
Oceanic crust is thinner and more dense, while continental crust is thicker and less dense.
What is oceanic crust and continental crust made of?
Oceanic crust is predominately made of basaltic rock with a thin layer of sedimentary rock on top. Continental crust is predominately made of granitic rock, with a thin layer of sedimentary rock covering much of the visible surface.
Which rock makes continental and oceanic crust?
Continental crust is made of granite. Oceanic crust is made of basalt.
What type of rock primarily makes up oceanic crust and continental crust?
Continental: granite oceanic: basalt
What makes up the continents and the ocean floor?
The continental and oceanic plates are primarily igneous rock. The continental crust is granitic and the oceanic crust is basaltic.
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 is the difference of continental crust and oceanic crust?

Most of the continental crust and oceanic crust is composed of what?
Igneous rock.
How do continental crust differ from oceanic?
Continental crust is predominantly composed mostly of rock of a granitic composition, higher in silica and aluminum, with layers of sedimentary rock above. Oceanic crust is predominantly basaltic (higher in iron and magnesium), darker, thinner, more dense, and formed from rapid cooling of lava.
Is the continental crust a solid liquid or gas?
The oceanic crust itself is made of solid rock.
How are oceanic crust and continental crust different?
Oceanic crust is thinner and more dense, while continental crust is thicker and less dense.
How is continental lithosphere different oceanic lithosphere?
Continental lithosphere is thicker and less dense than oceanic lithosphere. Continental crust is primarily composed of granitic rock while oceanic crust is composed primarily of basaltic rock.
Why are continental plates less dense than oceanic plates kids answer?
Continental crust and continental crust are made of different types of rock. The rocks in the continental crust do not contain as many of the heavier elements as the ones in the oceanic crust do.
What happens to mantle rock descending oceanic crust scrapes past continental crust?
The mantle rock descending from the oceanic crust causes the water in oceanic crust to be released. This lowers the melting point of the rock and causes it to melt.
