Does lithosphere or asthenosphere contain partly melted rock from the upper part of the mantle?
The Asthenosphere.
Does the mantle contain soil?
No, just molten rock.
What is Earth's upper mantle?
The asthenosphere is the upper part of Earth's mantle. It is partially molten (plastic rheology) and mechanically detached from the lithosphere, which is mostly the Earth's crust (but also a little bit of upper mantle). The density of the upper mantle is your mom! (yo mamma!)
A rigid block of crust and upper mantle-rock is known as what?
Lithosphere
What rock makes up the crust and upper mantle?
Felsic rocks.
Does lithosphere or asthenosphere contain partly melted rock from the upper part of the mantle?
The Asthenosphere.
What is the state of matter of the Earth's upper mantle?
The Earth's upper mantle is composed of solid rock that flows through liquid rock, also known as lava.
Why is the lower mantle denser the the upper mantle?
The lower mantle is under greater pressure than the upper mantle, compressing the rock into a denser form.
Is silica and forms of granite found in upper mantle?
Silica is found in the upper mantle, but not granite. Most of the minerals in the mantle are silicates, meaning they contain silica. Granite is found in the crust, primarily conditnental crust, as it forms from high-silica magma. The upper mantle is composed mostly of a lower-silica rock called peridotite.
How do upper mantle rock differ from lower mantle rock?
the upper-mantle rocks are heavier while the lower mantle rocks are semisolid like melted plastic

What is the layer of softer rock in the upper mantle?
lithosphere
The molten rock that is found in the upper mantle are?
Magma.
What is earths upper mantle composition?
hard rock
Does the mantle contain soil?
No, just molten rock.
Where does a peridotite rock come from?
Peridotite originates from the upper mantle.
Magma forms when solid rock in the crust and upper mantle?
Cools ^ If you took this answer then is Magma relevant to Ice? Magma forms when the solid rock in the crust and upper mantle melts. ^Why not erase it then?
