How many kilometers is the distance from the crust to the mantle?
The crust ranges from 2 miles to 70 miles(mid-ocean) thick. This is equivalent to 3.225 km to 112.9 km
What is the continental crust made out of?
continental crust is made of many rocks such as granite
How is the difference in density between the oceanic crust and the continental crust important?
Oceanic crust is thin, dense and composed of mainly silicon and magnessium While the Continental crust is thicker but less dense in comparism with the oceanic crust and its composed mainly of silicon and aluminium.
What are the 3 parts of Earth's internal structure?
These are the crust, mantle, and core. However, there is a distinct inner and outer core and a less distinct inner and outer mantle. There is also different types of crust so there are as many as 7 or 8 layers in the Earth's crust.
Facts about the earths crust?
The crust is about 40 kilometers thick in many places. The crust is the coldest layer of all the layers of earth. The crust makes up less than 1% of the earths mass. The crust is mainly made up of silicon,aluminum,calcium,sodium, and potassium.
How many miles thick is the crust?
about 25 miles thickoceanic crust is 4-7 miles thick and continental crust is an average of 20-25 miles with a maximum of about 45 miles
How many miles thick is the continental?
3000 miles to 5000
How many times thicker is the continental crust to the oceanic crust?
The continental crust is about 35 to 40 kilometers thick, while the oceanic crust averages at about 7-10 kilometers thick. This means that the continental crust is about 3.5 to 4 times the thickness of the oceanic crust.
Is the thickness of Earth's crust even around the planet?
falseThe Earth's crust is quite variable in density and thickness. Some places on the ocean floors it is many miles thinner than on land.
Is continental crust is made of rocks such as granite?
There are many different ryes of rocks in continental crust. Granite is one of the rocks that makes up continental crust.
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.
How many kilometers thick is the crust?
5 to 8 KM thick.
How many kilometers is the distance from the crust to the mantle?
The crust ranges from 2 miles to 70 miles(mid-ocean) thick. This is equivalent to 3.225 km to 112.9 km
How many km is the crust?
The crust is about five to forty kilmeters thick! 5-40km
How many tectonic plates are composed of only continental crust?
Some geologists believe there are no tectonic plates composed solely of continental crust, as plates typically consist of both continental and oceanic crust. The concept of a plate composed entirely of continental crust is not widely accepted in the field of plate tectonics.
What is the continental crust made out of?
continental crust is made of many rocks such as granite
Is the theory of the continental drift true?
Continental Drift is an obsolete name for the theory of Plate Tectonics and yes, it is true. It has been proved in many ways, by comparing the composition of oceanic crust and its ages with that of the continental crust, by plotting the reversals of magnetism in the oceanic crust and many other ways.
