After the crust and the mantle is the what?
After the crust and mantle, the next layer of the Earth is the outer core, which is composed of mostly liquid iron and nickel. Beneath the outer core is the inner core, which is a solid sphere primarily made of iron and nickel.
What are the 2 divisions of the crust?
The two divisions of Earth's crust are the continental crust and the oceanic crust. The continental crust is thicker and less dense, mainly composed of granite rocks, while the oceanic crust is thinner and denser, primarily made up of basalt rocks.
What is the crust and brittle upper mantle called?
Earth's crust and brittle upper mantle is called the lithosphere.
Where you the earths mantle located?
The Earth's mantle is located between the outer core and the Earth's crust. It is a layer of hot, dense rock that is primarily composed of silicate minerals. The mantle makes up the bulk of the Earth's interior and plays a key role in plate tectonics and the movement of the Earth's crust.
Does the crust and mantle have the same density?
No, the crust and mantle do not have the same density. The Earth's crust is less dense, primarily composed of lighter silicate minerals, while the mantle is denser due to its composition of heavier silicate and magnesium-rich minerals. Typically, the continental crust has a density of about 2.7 g/cm³, whereas the mantle density ranges from about 3.3 to 5.7 g/cm³, depending on depth and composition.
Explain the significance of the fact that the lithosphere is primarily composed of basalt while the crust is composed primarily of granite?
The lithosphere is composed of the oceanic and continental crust, along with the brittle uppermost mantle. The continental crust is mainly granitic, and the oceanic crust is primarily basalt.
Three of the four layers of this part of this crust are igneous material?
The Earth's crust has three primary layers: the lithosphere, mantle, and core. The lithosphere is primarily composed of igneous rocks such as basalt and granite. However, the core is primarily composed of metals, while the mantle is composed of silicate minerals.
The distinction between the crust and mantle is primarily on the basis of a difference in?
composition — the crust is primarily composed of lighter, silicate minerals like granite and basalt, while the mantle is composed of denser minerals like peridotite. This compositional difference contributes to variations in density, temperature, and behaviour between the crust and mantle layers of the Earth.
what- The oceanic crust is composed primarily of?
The oceanic crust is primarily composed of basalt, a type of volcanic rock that is rich in iron and magnesium. Basalt is formed when magma from the Earth's mantle erupts at mid-ocean ridges and solidifies to create new oceanic crust.
Much of the upper mantle thought to be made of granite true or false?
False. The upper mantle is believed to be composed primarily of peridotite.
Does the moon have a mantle?
Yes, however there is no clear boundary between crust and mantle as both are basaltic and stationary. There is a small solid iron core.
Earth is composed what of main three layers?
Crust, mantle, and core
Why does Earth's crust sit on top of the mantle?
The crust lies on top of the mantle because it is composed of less dense materials than the mantle is. The crust is essentially floating on the mantle.
Which layers of the earth contains rocks?
The rocks are primarily found in the Earth's crust, mantle, and core. The crust is the outermost layer and consists of solid rock. The mantle is composed of solid and semi-solid rock, while the core is mostly made of metal.
What layer of earth is made up of crust and mantle?
The lithosphere is composed of the crust and hard uppermost attached mantle.
What is the definition of the crust mantle core?
The Earth's crust is the outermost layer of the planet, composed of solid rock. The mantle is the layer beneath the crust and is made up of hot, semi-solid rock. The core is the innermost layer, consisting of a solid inner core and a liquid outer core, primarily composed of iron and nickel.
After the crust and the mantle is the what?
After the crust and mantle, the next layer of the Earth is the outer core, which is composed of mostly liquid iron and nickel. Beneath the outer core is the inner core, which is a solid sphere primarily made of iron and nickel.
