Most significantly, there is a material difference in the weight and density of the two types of crust. This manifests itself when tectonic movement brings oceanic in continental plates into collision. Oceanic crust is relatively denser but typically about 100km this. Continental crust is lighter but almost twice as thick--about 200km.
What else can I help you with?
What are two kinds of crusts?
oceanic and the continental 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
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.
Are oceanic or continental crusts more buoyant?
Continental crust is more buoyant than oceanic crust because it is thicker and composed mainly of less dense rocks like granite, whereas oceanic crust is thinner and denser due to its basaltic composition. This difference in density causes continental crust to float higher on the mantle, making it more buoyant.
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 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.
What are convertgent boundaries?
A conversion boundary is a place where 2 tectonic plates are mving toward each other. There are 3 types of convergent boundaries OCEANIC CRUST-OCEANIC CRUST OCEANIC CRUST-CONTINENTAL CRUST CONTINENTAL CRUST-CONTINENTAL CRUST They are classified according to their crust
Why does continental crusts stand higher on the mantle then oceanic crust?
Continental crust is less dense than oceanic crust because it is made up of mostly granitic rocks, while oceanic crust is composed of denser basaltic rocks. This difference in density causes continental crust to "float" higher on the underlying mantle, creating land above sea level.
What happens when a plate Carrying oceanic crust collides with a plate carrying continental crusts?
The contiental cdrust is forced under the continental crust in a process called subduction.
What are the two crusts found on earth?
The earth's crust is comprised of the oceanic crust and the continental crust. Bread has the crunchy and the sofy crust.
How are continental crust and oceanic crust are alike?
Oceanic and continental crust contain the same elements. Both also move and shift and grow continuously. They are different because of their density.
