Earths lower mantle lies just below the upper mantle extending from 400 to 2,900 kilometers below the Earth's surface. This region primarily consists of dense, solid rock materials that experience high pressures and temperatures. The lower mantle plays a significant role in the Earth's mantle convection, which drives tectonic plate movements and heat transfer within the Earth.

Which of the Earths layers is just below lower mantle?
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.
What is the lower part of the mantle in the earth's crust?
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.
What is the least rigid part of the mantle?
The asthenosphere is the least rigid part of the mantle. It is a semi-fluid layer just below the lithosphere that allows the tectonic plates to move.
Is it true that the earth's mantle lies directly below the inner core?
No, the Earth's mantle lies directly below the Earth's crust and extends down to the outer core. The inner core is a solid metallic sphere at the center of the Earth.
What is the temperature of the earths asthenosphere in degrees celsius?
The temperature of the Earth's asthenosphere is estimated to range between 1300°C and 1600°C.
Which of the Earths layers is just below lower mantle?
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.
What is above the lower mantle?
The middle mantle is just above the lower mantle.
What is the lower part of the mantle in the earth's crust?
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.
What parts of earths structure combine to form lithosphere?
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
What is the least rigid part of the mantle?
The asthenosphere is the least rigid part of the mantle. It is a semi-fluid layer just below the lithosphere that allows the tectonic plates to move.
How far down is the earths upper mantle?
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.
Which of the Earth's layers is located just below the 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.
inner core?
the layer of the earth just below the mantle mode of more soild material
What is just below the Earth's crust?
Just below the Earth's crust is the mantle, which is a layer of hot, solid rock. The mantle extends down to around 1,800 miles beneath the Earth's surface and is responsible for much of the Earth's heat and geological activity.
What is a good website for the earths layers?
I just studied them. They are: Crust, Mantle, Outer Core and Inner Core
Is it true that the earth's mantle lies directly below the inner core?
No, the Earth's mantle lies directly below the Earth's crust and extends down to the outer core. The inner core is a solid metallic sphere at the center of the Earth.
What is the mantle's definition?
the layer of earth just below the crust ; lava
