What is the main type of rock in oceanic crust?
The main type of rock in oceanic crust is basalt. Basalt is a fine-grained igneous rock formed from the rapid cooling of lava at or near the Earth's surface. It is dark in color and rich in minerals like pyroxene and plagioclase feldspar.
Crust under the ocean is called?
Crust under the oceans is called oceanic crust.
What is the compition for the crust?
Crust is made up of mainly granite, a felsic rock wit a lower density than basalt, what makes up the ocean's crust, thus why the continental crust rises up compared to ocean crust.
Which type of crust is primarily made of basalt and is more dense?
Oceanic crust is primarily made of basalt and is more dense than continental crust. It is also younger and thinner compared to continental crust.
What is the composition of ocean crust?
It is mostly composed of basalt, and few other mineral types. It is made mostly of igneous rock, same with continental crust.
What is ocean crust made of?
The oceanic crust is made out of basalts - (lava-hardened Iron/Magnesium Silicate mixtures which solidified rapidly).
The thinner but more dense crust of the earth?
The thinner but more dense crust of the Earth is found beneath ocean basins and is known as oceanic crust. It is made up of dense basalt rock and is thinner than the continental crust. This crust is constantly being formed and destroyed through the process of seafloor spreading and subduction, respectively.
Is continental crust made mostly of basalt and is about 6 to 11 kilometers thick?
The oceanic crust is mostly basalt.
Is the oceanic crust made of solid or liquid?
The oceanic crust is primarily made of solid rock, primarily basalt. However, beneath the oceanic crust, there is a layer of partially molten rock called the mantle that flows slowly over time.
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?
The rock that makes up both continental and oceanic crust is called basalt. Basalt is a mafic extrusive igneous rock that forms when lava cools and solidifies rapidly at the Earth's surface. It is commonly found in oceanic crust, while continental crust is made up of a variety of rocks including 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.
