Does lithosphere or asthenosphere contain partly melted rock from the upper part of the mantle?
The asthenosphere contains partly melted rock from the upper part of the mantle, while the lithosphere is a rigid layer of the Earth's crust and upper mantle that does not contain melted rock. The asthenosphere's semi-fluid behavior allows tectonic plates to move across it.
What rock makes up the crust and upper mantle?
The predominant rock in the Earth's crust and upper mantle is called silicate rock, composed mainly of silicon and oxygen. This type of rock is known as "peridotite" in the mantle and "granite" in the crust.
Can you infer why p waves travel faster through He upper mantle than they do thought the crust?
P waves travel faster through the upper mantle because it is composed of denser rock materials compared to the crust. The higher density allows the seismic waves to propagate more efficiently through the upper mantle, resulting in higher velocity. Additionally, the upper mantle is composed of more solid rock material, while the crust may contain more heterogeneous and less dense materials that can slow down the waves.
What is the state of the upper mantle?
The upper mantle is a solid layer of rock located beneath the Earth's crust. It is part of the Earth's mantle and extends from the base of the crust to a depth of about 660 kilometers. The upper mantle is mostly composed of peridotite, a dense rock made up of minerals like olivine and pyroxene.
What layers make up the mantle?
The mantle consists of two main layers: the upper mantle and the lower mantle. The upper mantle is composed of solid rock that can flow slowly over time. The lower mantle is composed of solid rock under high pressure and temperature conditions.
Does lithosphere or asthenosphere contain partly melted rock from the upper part of the mantle?
The asthenosphere contains partly melted rock from the upper part of the mantle, while the lithosphere is a rigid layer of the Earth's crust and upper mantle that does not contain melted rock. The asthenosphere's semi-fluid behavior allows tectonic plates to move across it.
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 earths upper mantle composition?
hard rock
What is the layer of softer rock in the upper mantle?
lithosphere
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.
