What causes the rock in the mantle at divergent boundaries to melt?
The crust stretches and gets thinner so the pressure decreases on the mantle rocks below this causes part of the mantle to melt
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.
What is the layer below the earths crust called?
the mantle then the outer core then the inner core
What is the plastic zone below the upper mantle?
The plastic zone below the upper mantle is called the asthenosphere. It is a semi-fluid layer of the upper mantle where rock can flow like a viscous fluid over long periods of time. The asthenosphere plays a crucial role in the movement of tectonic plates.
What is the layer 100km below the surface?
The layer 100km below the surface is known as the asthenosphere. It is a semi-fluid layer within the upper mantle of the Earth where rock is ductile and able to flow slowly over time.
The section of earth beneath the crust?
Mantle Is The Below Layer Of The Crust In Earth.
What is below the crust?
Below the Earth's crust is the mantle, which comprises a hot, semi-solid layer of rock. This layer extends down to about 1,800 miles (2,900 kilometers) below the surface and is composed of solid molten rock and minerals. Below the mantle is the outer core, made of liquid iron and nickel, followed by the solid inner core at the center of the Earth.

Which two layers of the earth are made of rock?
The two layers of the Earth that are made of rock are the crust and the mantle. The crust is the outermost layer and is composed of solid rock, while the mantle lies just below the crust and consists of solid rock that is capable of flowing over long periods of time.
The section of the earth below the crust?
The mantle. Molten rock, but not as high of a temperature as the actual core.
Does the mantle lie directly below the inner core?
No, the mantle does not lie directly below the inner core. The mantle is the layer of the Earth located between the outer core and the crust. It is composed of solid rock that can flow slowly over time due to high temperatures and pressures. The inner core is a solid sphere of iron and nickel at the center of the Earth.
What rock can flow like a liquid?
the rock that can flow like a liquid is a mantle because the mantle has two parts. The upper part is the solid rock. The solid rock of the mantle is part is the lithosphere. Below the solid rock, the mantle rock has the ability to flow like a liquid. Most of the mantle is made up of rock that can flow. Sanjida Ahmed 752/753

What are the Asthenospheric mantle and the Inner Mantle are made up of?
The Asthenospheric mantle and the Inner mantle are made up of solid rock and liquid rock.

The layer 100km below the surface is known as the asthenosphere. It is a semi-fluid layer within the upper mantle of the Earth where rock is ductile and able to flow slowly over time.
