Earth's mantle is a rocky shell about 2,890 km (1,800 mi) thick that constitutes about 84 percent of Earth's volume. Two main zones are distinguished in the upper mantle: the inner asthenosphere composed of flowing rock in the state of plasticity, about 200 km thick, and the lowermost part of the lithosphere, composed of rigid rock, about 50 to 120 km thick. A thin crust, the upper part of the lithosphere, surrounds the mantle and is about 5 to 75 km thick. The mantle is divided into sections which are based upon results from seismology. These layers (and their depths) are the following: the upper mantle (starting at the Moho, or base of the crust around 7 to 35 km, downward to 410 km), the transition zone (410-660 km), the lower mantle (660-2891 km), and in the bottom of the latter region there is the anomalous D" layer with a variable thickness (on average ~200 km thick)

How many layers in earths mantle?

The Earth's mantle has two main layers: the upper mantle and the lower mantle. These layers are distinguished by differences in their composition, temperature, and behavior. The upper mantle extends from the crust to a depth of about 410 miles (660 kilometers), while the lower mantle extends from about 410 miles (660 kilometers) to approximately 1,800 miles (2,900 kilometers) below the Earth's surface.


What is the depth of each or earths layers?

The Earth's structure consists of three main layers: the crust, mantle, and core. The crust varies in thickness from about 5 to 70 kilometers, with oceanic crust being thinner than continental crust. Beneath the crust, the mantle extends to about 2,900 kilometers deep. The core, which is divided into a liquid outer core and a solid inner core, extends from approximately 2,900 kilometers to the Earth's center at about 6,371 kilometers deep.


Is earths mantle 3000 kilometers thick?

The Earth's mantle is not a uniform thickness, but on average it is approximately 2,900 kilometers thick. The depth can vary depending on location, ranging from about 100 kilometers beneath ocean basins to over 200 kilometers beneath continental areas.


Where is the upper mantle located?

The upper mantle is located beneath the Earth's crust, extending from about 30 to 400 kilometers deep. It is part of the Earth's mantle layer, which lies between the crust and the core.


Is the earths mantle made of liquid?

No. The Earth's mantle is a ductile solid.

If you dug a hole 592 kilometers deep which layer of the Earth would you reach?

If you dug a hole 592 kilometers deep, you would reach the upper part of the Earth's mantle, which extends from the crust to about 2,900 kilometers beneath the surface. You would not reach the Earth's outer core, which starts at a depth of about 2,900 kilometers.


How far is the mantle away from the crust of the earth?

The mantle is located directly beneath the Earth's crust and is approximately 1,800 miles (2,900 kilometers) thick. The boundary between the crust and the mantle is known as the Mohorovičić discontinuity or Moho.
