- 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.
What else can I help you with?
Which stress force pulls on the crust and stretches rock?
Tensional stress force pulls on the crust and stretches rock. This type of stress occurs where tectonic plates are moving away from each other.
Where in the world is gabbro found?
Oh, dude, gabbro is found all over the place! It's a common type of rock that's typically found in oceanic crust and in some mountain ranges. So, like, if you're out exploring and you stumble upon some dark, coarse-grained rock, there's a good chance it could be gabbro. Just remember to say hi if you run into it!
What is the most common type of unconformity?
The most common type of unconformity is an angular unconformity, where older tilted layers of rock are overlain by younger horizontal layers, indicating a period of deformation and erosion before deposition of the younger layers.
What is the true age of a rock or fossil?
The method used will be determined by the rock type, but the age of a rock will be determined by a determination of the amount of decay of a radioactive isotope, either contained in the rock, or in a geologic layer of rock coinciding with a fossil.
From the main coon the bengal the chetoh the savannah and the toyger what is their hair type long or short?
From the main coon the Bengal the cheetah and the tiger have long type of hair.
In earths crust What type of rock is found under the oceans?
Oceanic crust, new oceanic crust is produced by seafloor spreading.
What part of the crust is made of dark igneous basalt type rock?
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.
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.
The mineral composition of the oceanic crust is similar to the composition of what rock?
The mineral composition of the oceanic crust is similar to the composition of basalt rock. Basalt is a type of volcanic rock that contains minerals such as feldspar, pyroxene, and olivine, which are also commonly found in the oceanic crust.
What is the color and the type of rock that forms oceanic crust at mid ocean ridges?
The color of rock that forms oceanic crust at mid-ocean ridges is usually dark gray to black. The type of rock is basalt, which is rich in iron and magnesium and forms from solidified lava.
What is the color and type of rock that forms oceanic crust at mid-ocean ridges?
The color of the rock that forms oceanic crust at mid-ocean ridges is dark gray to black. The rock is primarily basalt, which is a type of igneous rock formed from the solidification of molten lava.
What is continental and oceanic crust?
Continental crust is the thicker, less dense, and older type of crust found beneath continents, primarily composed of granite and sedimentary rock. Oceanic crust is the thinner, more dense, and younger type of crust located beneath oceans, primarily composed of basalt. The boundary between continental and oceanic crust is known as the continental-oceanic crust boundary.
What type of rock primarily makes up oceanic crust and continental crust?
Oceanic crust is primarily made up of basaltic rock, which is dense and rich in iron and magnesium. Continental crust is composed mainly of granite and other lighter silicate rocks, which are less dense than basalt.
What is the most abundant type of rock?
Igneous. Basalt is the most abundant in oceanic crust and granite is the most abundant in continental crust.
What is the main mineral type that makes up the oceanic plates?
rock
What is the other type of crust the continental crust and what?
Oceanic Crust
