What is the Texture of mantle?
the mantle is a hard rock in the upper Mantle and softer lower down.also the texture of it is coarse and solid. the colour of it is an Orange red colour.
Is the asthenosphere a plastic layer of rock in the mantle or is it a layer of earths crust and mantle?
The asthenosphere is a plastic layer of rock located in the upper mantle, below the lithosphere (earth's crust and uppermost mantle). It is responsible for the movement of tectonic plates due to its partially molten and ductile nature.
Earths middle layer?
The middle layer of the Earth is called the mantle. It is a region of solid rock that extends from the base of the crust to the outer core. The mantle is composed of silicate minerals and is divided into the upper mantle and the lower mantle.
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.
Which layer of the earth does the magma form?
Magma forms in the mantle layer of the Earth. It is a molten rock material that originates from the partial melting of rocks in the upper mantle. Magma can rise to the Earth's surface through volcanic eruptions.
What does the upper mantle and lower mantle form?
The upper mantle and lower mantle together form the Earth's mantle, which is the layer of rock between the Earth's crust and core. This region plays a critical role in plate tectonics and the movement of Earth's lithosphere.
What layer is Composed of peridotite?
The layer composed of peridotite is the mantle, which is located between the Earth's crust and core. Peridotite is the main rock type found in the upper mantle and is rich in minerals such as olivine and pyroxene.
What is the athenosphere made out of?
The asthenosphere is composed of partially melted, ductile rock that lies beneath the Earth's rigid lithosphere. It is located in the upper mantle and its low viscosity allows for the movement of tectonic plates.
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 most expansive layer of the Earth?
The most expansive layer of the Earth is the mantle, which makes up about 84% of the Earth's volume. It is located between the Earth's crust and the core and consists of solid rock that can flow slowly over long periods of time.
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!)
The layer between earth's core and its crust is called?
There is no layer of melted rock directly below the Earth's crust. The upper mantle is composed of solid, but flexible rock which is prevented from melting by the pressure of surrounding material.
