What is the upper mantle's depth?
2 in.
What are two types of mantles?
The two types of mantles are the oceanic mantle and the continental mantle. The oceanic mantle is found beneath the ocean floor, composed primarily of mafic rocks like basalt, and is generally thinner than its continental counterpart. The continental mantle, on the other hand, lies beneath continental crust and consists of a more diverse range of rock types, including granitic compositions, and is usually thicker and less dense. Together, these mantles contribute to the overall structure and dynamics of the Earth's lithosphere.
Why is the mantle divided into 2 layers?
The mantle is divided into two layers, the upper mantle and the lower mantle, based on differences in temperature, pressure, and rock composition. The upper mantle is closer to the Earth's surface and is more rigid, while the lower mantle is hotter and flows more easily due to higher temperatures and pressures.
What is the mineralogy of earths mantle?
The Earth's mantle is primarily composed of silicate minerals rich in magnesium and iron. The dominant mineral types include olivine, pyroxenes, and garnet, with olivine being the most abundant at the upper mantle. The mantle also contains other minerals like peridotite and eclogite, which can form under high-pressure conditions. Overall, these minerals contribute to the mantle's properties, including its ability to flow slowly over geological time.
What are the three parts (layers) of the earth?
These are the crust, mantle, and core. However, there is a distinct inner and outer core and a less distinct inner and outer mantle. There is also different types of crust so there are as many as 7 or 8 layers in the Earth's crust.
What are the types of mantles?
the upper mantle(lithosphere)and the lower mantle(mesosphere)
How tall is Clive Mantle?
Clive Mantle is 6' 5 1/2".
What types of rock is in the mantle?
the mantle is made up of solid hot rock.
What is the upper mantle's depth?
2 in.
What is the depth of upper mantle?
2 in.
What are the 2 layers of the mantle?
The mantle is divided into two main layers: the upper mantle and the lower mantle. The upper mantle is closer to the Earth's crust and is more rigid, while the lower mantle is hotter and flows more easily due to higher temperatures and pressures.
How many parts does the mantle have?
The mantle is typically divided into two parts: the upper mantle and the lower mantle. The upper mantle sits beneath the Earth's crust and extends to a depth of about 410 kilometers, while the lower mantle extends from 410 to 2,890 kilometers below the Earth's surface.
How many layers has the mantle got?
The mantle is one of the four layers 1.crust 2.mantle 3.outer core 4.inner core

What the lithosphere contains?
Earth contains a lithosphere that contains the crust and the mantle. There are two types of lithospheres on earth which are the oceanic and the continental.
