What is the layer that makes up most of the earth's mass and vloume is the is what?
The layer that makes up most of the Earth's mass and volume is the mantle. It is located between the Earth's crust and core and is composed of solid rock that is capable of flowing over long periods of time. The mantle is divided into the upper mantle and the lower mantle, with the upper mantle being partially molten and the lower mantle being solid.
Mostly solid rocky part of the earth from center of core to the surface of the crust?
The mostly solid rocky part of the Earth extending from the center of the core to the surface of the crust is known as the mantle. It is divided into the upper mantle and the lower mantle, and consists mainly of solid rock composed of silicate minerals. The uppermost part of the mantle is partially molten, forming the asthenosphere.
What parts of the mantle contains molten material?
The upper part of the mantle, known as the asthenosphere, contains molten material. This region is partially molten, allowing for the movement of tectonic plates. Deeper parts of the mantle, such as the lower mantle, contain solid rock due to higher pressures and temperatures.
Is mantle a compositional layer?
Yes, the mantle is considered a compositional layer of the Earth. It lies between the crust and the outer core and is primarily composed of silicate minerals rich in magnesium and iron. The mantle exhibits different properties in its upper and lower regions, with the upper mantle being partially molten and involved in tectonic activity, while the lower mantle is more solid and extends to the outer core.
What three of the 4 layers of this crust are igneous material?
The layers of Earth's crust that consist mostly of igneous material are the uppermost layer, the oceanic crust, and the lowermost layer, the lower continental crust and lithospheric mantle. These layers are primarily composed of igneous rocks formed from the cooling and solidification of molten rock.
What happens to the crust when the molten rock sinks to the lower mantle?

What is the lower mantle beneath?
The lower mantle is beneath the crust.
Which earth layer is found under the crust?
35 - 60 Kms would be the uppermost mantle, which along with the crust forms the hard, brittle lithosphere. The Mantle is a semi-molten layer.
What are the layers of the mantle?
The mantle is divided into two main layers: the upper mantle and the lower mantle. The upper mantle is further divided into the lithosphere and the asthenosphere. The lithosphere is rigid and made up of the crust and the upper part of the mantle, while the asthenosphere is semi-molten and capable of flowing.
How do you make a sentence with upper mantle?
The crust and upper mantle make up the earth.

The uppermost part of the mantle is partially molten, forming the asthenosphere.
Why does the oceanic crust sit lower in the mantle than the continental crust?
Oceanic crust is denser than continental crust due to its composition and age, causing it to sink lower into the mantle. The oceanic crust is also thinner and has been subjected to more intense heat and pressure, which contributes to its lower position in the mantle compared to the thicker, lighter continental crust.
How many kinds of crust are there?
only 1 crust. then the lithosphere, upper mantle, lower mantle, outer core, inner core.
What parts of the mantle contains molten material?
The upper part of the mantle, known as the asthenosphere, contains molten material. This region is partially molten, allowing for the movement of tectonic plates. Deeper parts of the mantle, such as the lower mantle, contain solid rock due to higher pressures and temperatures.
