The lithosphere, which consists of the crust and uppermost mantle, is considered hard and brittle, unlike the asthenosphere, where rock is considered ductile.
Earth's crust and brittle upper mantle is called the lithosphere.
The lithosphere consists of the crust and the rigid, uppermost part of the mantle.
The crust and the upper part of the mantle are the solid part of the Earth called the lithosphere.
The lithosphere is composed of the crust and uppermost hard, brittle mantle.
Tectonic plates are formed from the lithosphere which is the solid brittle portion of the upper mantle and the crust so tectonic plates are part of both the crust and the upper brittle mantle.
The lithosphere is composed of the crust and uppermost hard, brittle mantle.
The lithosphere includes the crust and the very top of the mantle. The lithosphere is cool and brittle.
Earth's crust and brittle upper mantle is called the lithosphere.
The lithosphere is made up of the crust and uppermost brittle mantle.
The lithosphere is made up of the crust and uppermost brittle mantle.
The Lithosphere
The lithosphere consists of the crust and the rigid, uppermost part of the mantle.
It consists of the crust and the uppermost brittle mantle.
The crust and uppermost brittle mantle are referred to as the lithosphere.
The uppermost mantle and the crust makes the lithosphere.
In order to answer this you need to understand the difference between the compositional layers of the earth and the physical layers. The crust and mantle are differing layers of the earth based on chemical composition. The lithosphere is a layer of the earth defined based on it's physical or mechanical properties (how it deforms). The lithosphere is composed of the crust and the portion of the upper mantle which deforms elastically and fails in a brittle manner (fractures can propagate through the material). So in the question where you ask is the crust and lithosphere brittle, the answer is yes as the crust is entirely part of the lithosphere which by definition is brittle. However as described above, a section of the upper mantle is also a brittle solid and so that too is part of the lithosphere. However below this, the mantle behaves as a ductile solid.
The crust and the upper part of the mantle are the solid part of the Earth called the lithosphere.
