Earth's crust and its upper mantle is called?

The lithosphere is the crust Moho and upper mantle. It floats on a plasticity zone called the asthenosphere.


What part of the earth do the crustal plates float?

The Earth's crust, also called the lithosphere, floats on the upper layer of the mantle. This part of the mantle is known as the asthenosphere.


What is the crust and the upper mantle are called?

The crust and uppermost hard rocky mantle, together, is known as the lithosphere, which is above the plastic-like upper mantle area known as the asthenosphere.


Is the lithosphere a solid that floats on the inner part of the mantle?

Yes, the lithosphere is the rigid outer layer of the Earth that consists of the crust and the upper part of the mantle. It is broken into tectonic plates that float on the semi-fluid asthenosphere below.


The crust and uppermost mantle make up the rigid outer layer of earth called the?

The uppermost mantle and the crust makes the lithosphere.


Which layer of earth contains both the crust and upper mantle?

The layer of the Earth that contains both the crust and the upper mantle is called the lithosphere. The lithosphere is a rigid outer shell that is broken into tectonic plates that float on the semi-fluid asthenosphere below.


How is the lithosphere different then the adthosphere?

The lithosphere is defined as the crust plus the brittle, uppermost mantle to which it is attached. The part of the upper mantle called the asthenosphere is ductile, and is the portion of the mantle on which the lithosphere 'floats'. Essentially, it is a difference in the degree of ductility. The lithosphere is brittle; the mantle is ductile.


Soft layer of the mantle on which the lithosphere floats?

The soft layer of the mantle on which the lithosphere floats is called the asthenosphere. It is a partially molten layer that allows for the movement of tectonic plates due to its weak and ductile properties. The lithosphere, which is the rigid outer layer of the Earth, sits on top of the asthenosphere and moves due to the convection currents in the mantle beneath it.


What is the earth's crust and upper part of the mantle called?

Lithosphere


Solid layer just below the lithosphere?

The lithosphere is the physical layer of the Earth that contains the crust and the brittle uppermost mantle.


What is the land part of earth called?

The land part of Earth is called the lithosphere. It consists of the Earth's crust and the uppermost part of the mantle.


What is the solid outer crust layer and the top portion of the mantle layer of the Earth called?

The solid outer crust layer of the Earth is called the lithosphere. The top portion of the mantle layer, just beneath the lithosphere, is called the asthenosphere.
