The oceanic crust is made up of mafic rocks which is rich in magnesium and iron. These rocks are also referred to as sima.
The oceanic crust is similar to the continental crust, except it is thinner yet denser.
What else can I help you with?
What layer of the earth can you find continents and oceans?
Continents and oceans are found on Earth's crust, which is the outermost layer of the Earth. The continents are made up of thicker continental crust, while the oceans are located on thinner oceanic crust.
Is the crust made out of a liquid or a solid?
No, The crust is solid. The oceans just happen to sit on top of it.
Which two layers of the earth are liquid?
The two layers of earth that are made up of liquids are the crust and the outer core. The crust is the surface of the earth which is where the oceans are. The outer core is made up of iron and is the creator of the earths magnetic field.
In earth's crust what are two types of crust?
sial and sima - sial is surface crust on land, made of silicate and aluminium. sima is the deep crust found in oceans, made of silicate and magnesium
What is the upper section of the lithosphere?
The upper section of the lithosphere is known as the crust. It is made up of solid rock that includes both continental crust, found beneath landmasses, and oceanic crust, found beneath oceans. The crust is the outermost layer of the Earth's surface.
Where is the crust thicker oceans or continents?
The crust is typically thicker beneath continents compared to oceans. Continental crust can be up to 40 km thick, while oceanic crust is generally around 5-10 km thick.
Crust under the ocean is called?
Crust under the oceans is called oceanic crust.
How thick is the crust where the oceans are?
Roughly 3 up to 6 miles.
What do you call the crust making up the continents?
The crust that makes up the continents, or land masses on Earth is called continental crust. The crust that makes up the oceans is called oceanic crust.
Where is the crust thicker - under the continental shelf or under the oceans?
The crust is typically thicker under the continental shelf compared to under the oceans. This is because the continental crust is made of lighter granite rocks which are less dense than the basaltic rocks of the oceanic crust, resulting in thicker continental crust.
What is the crust beneath the oceans?
Oceanic Crust
They make up the crustal rocks found beneath the oceans?
The mantle is the layer of the Earth beneath the crust that is composed of solid rock. The mantle is made up of silicate minerals rich in magnesium and iron. It is generally denser than the crust and accounts for a significant portion of the Earth's volume and mass.
