What is ocean crust made of?
The oceanic crust is made out of basalts - (lava-hardened Iron/Magnesium Silicate mixtures which solidified rapidly).
What are the earths plates made of?
parts of the crust and upper mantle
Why are the continents placed above the oceans?
Because continental crust is less dense and thicker than oceanic crust, it "floats" higher on the underlying mantle rock. Notice how high the continental crust rises above the oceanic crust in this cross section of the North American Plate. Oceanic crust is made of dense basalt; continental crust consists of less dense granite
What are the two main types of crust on earth?
Oceanic crust-made up primarily of basalt-4-5 kilometers deepContinental crust-made up of granite-low density: allows it to "float" on the much higher density mantle below-20-30 miles deep
How does new oceanic crust form at a divergent boundary?
According to Google, Magma from the mantle solidifies into basalt, a dark, dense rock that underlies the ocean floor. Thus at divergent boundaries, oceanic crust, made of basalt, is created. When two plates come together, it is known as a convergent boundary
Would it be easier to drill through the oceanic crust or the continental crust?
Continental crust is easier. Continental crust is less dense than oceanic crust, which is made of basalt. (Basalt is very dense.)
The oceanic crust is made up mostly of dense rock called what?
basalt
What is the main type of rock in oceanic crust?
The crust is divided into two types: oceanic crust and continental crust. Oceanic crust, found under the ocean floor, is made of dense rocks such as basalt. It is about 7 kilometers (4 miles) thick. Continental crust, found under land masses, is made of less dense rocks such as granite.
Are basaltic igneous rocks lower in density than granitic rocks?
Granite is very much less dense than basalt. This is why the continental crust (mostly composed of granite) floats on Oceanic crust (made mostly of basalt). Granite is 70 % silicon. Where basalt is mainly pyroxene.
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.
How are oceanic and continental crust alike and 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.
Is continental crust made mostly of basalt and is about 6 to 11 kilometers thick?
The oceanic crust is mostly basalt.
What is the crust beneath the ocean made up basalt?
yes, it is made up of basalt, if that was your question.... ;)
The two types of crust?
Oceanic and Continental crust. Oceanic crust is made of basalt. Continental crust is made of granite
Which rock makes continental and oceanic crust?
Continental crust is made of granite. Oceanic crust is made of basalt.
What is the rock that makes up most of oceanic crust?
Most of the oceanic crust is made of peridotite. Some basalt and gabbro may also be found.
What is ocean crust made of?
The oceanic crust is made out of basalts - (lava-hardened Iron/Magnesium Silicate mixtures which solidified rapidly).
