What is the dominant rock type in the ocean crust and in the continental crust?
The dominant rock type in ocean crust is basalt, which forms from solidified lava. In continental crust, the dominant rock type is granite, which forms from the cooling and solidification of magma beneath the Earth's surface.
What part of the crust is made of dark igneous basalt type rock?
Oceanic crust.
What type of rock is the oldest continental crust made of?
Granite
Both oceanic and continental crust are composed of this?
Both oceanic and continental crust are composed primarily of igneous rocks, but they have different overall compositions. Oceanic crust is primarily made up of basalt, which is a type of volcanic rock, while continental crust is predominantly composed of granite, a type of intrusive igneous rock. Additionally, continental crust is generally thicker and less dense than oceanic crust.
What is the major component of oceanic crust?
The major component of oceanic crust is basalt, which is a type of mafic rock that forms from solidified volcanic lava flows. Basalt is rich in iron and magnesium and is the most common rock type found in the oceanic crust.
What is the dominant rock type in the ocean crust and in the continental crust?
The dominant rock type in ocean crust is basalt, which forms from solidified lava. In continental crust, the dominant rock type is granite, which forms from the cooling and solidification of magma beneath the Earth's surface.
What type of rock is found in continental crust?
All three rock types are found in continental crust, with a preponderance of granitic type igneous rock.
What part of the crust is made of dark igneous basalt type rock?
Oceanic crust.
What is the most common type of rock in the earth?
Continental crust--granite. Oceanic crust--basalt.
What are the two types of crust and what type of rocks are they made of?
igneous rock and sedimentary rock
What type of rock is the oldest continental crust made of?
Granite
What rock makes up 90 percent of the earth's crust?
Igneous rock comprises the majority of Earth's crust.
In earths crust What type of rock is found under the oceans?
Oceanic crust, new oceanic crust is produced by seafloor spreading.
What rock makes up the crust and upper mantle?
The predominant rock in the Earth's crust and upper mantle is called silicate rock, composed mainly of silicon and oxygen. This type of rock is known as "peridotite" in the mantle and "granite" in the crust.
Is granite part of the crust layer of the earth?
Yes, granite is a type of rock that is commonly found in the Earth's crust layer. It is an igneous rock that forms from the cooling and solidification of magma below the Earth's surface.
What is the most common type of rock found on the Earth’s crust?
Igneous
Both oceanic and continental crust are composed of this?
