Upper Mantle. This is also called the Asthenosphere
The layer just below the lower mantle is the outer core. This layer is composed of liquid iron and nickel, and is responsible for generating Earth's magnetic field.
The lower part of the mantle in Earth's crust is called the lower mantle. It lies beneath the upper mantle and extends from about 670 to 2,900 kilometers below the Earth's surface. It is composed of solid rock that can flow slowly over very long periods of time.
The upper mantle is less rigid because the pressure is lower
Earth's mantle lies roughly between 30 and 2900 km below the surface, .... decreases more rapidly with height than does a rising hot plume
The asthenosphere lies just below the lithosphere and composes the upper part of the Earth's mantle. Its temperature is 1300 degrees Celsius.
The layer just below the lower mantle is the outer core. This layer is composed of liquid iron and nickel, and is responsible for generating Earth's magnetic field.
The middle mantle is just above the lower mantle.
The lower part of the mantle in Earth's crust is called the lower mantle. It lies beneath the upper mantle and extends from about 670 to 2,900 kilometers below the Earth's surface. It is composed of solid rock that can flow slowly over very long periods of time.
The layer just below Earth's crust is the mantle. It is the thickest layer, and is composed of flowing rock material. The solid upper part of the mantle joins with the crust to form the lithosphere
The upper mantle is less rigid because the pressure is lower
The upper mantle of Earth begins just beneath the crust, which ranges in thickness from about 5-70 km (3-44 miles) depending on the location. The upper mantle extends to a depth of about 670 km (416 miles) beneath the Earth's surface, marking the boundary with the lower mantle.
The layer located just below the mantle is the outer core. It is composed of a liquid layer of iron and nickel that surrounds the solid inner core of the Earth.
the layer of the earth just below the mantle mode of more soild material
The D" layer (pronounced D double prime layer) forms the base of the Earth's lower mantle. Below this lies the outer core. This boundary zone is marked by a seismic discontinuity known as the Gutenberg discontinuity.
I just studied them. They are: Crust, Mantle, Outer Core and Inner Core
