What layer of the mantle contains tectonic plates?
The Lithosphere contains the tectonic plates. :)
Is the lower portion of the crust and the upper portion of the mantle called the core?
It is the Asthenosphere
What part of the mantle is made of soft rock that bends like plastic.?
A portion of the upper mantle known as the asthenosphere.
What two layers make up the lithosphere?
The lithosphere is the rigid outermost shell of a rocky planet. It comprises the crust and the portion of the upper mantle that behaves elastically on time scales of thousands of years or greater.In the Earth, the lithosphere includes the crust and the uppermost mantle, which constitute the hard and the crust.Also, in the Earth, the lithosphere is more in the crust, than in the uppermost mantle.
Does the lithosphere have a greater temperature than the earth's mantle?
The lithosphere is the upper portion of the mantle. Its temperature is around 300 to 500 degrees Celsius. The lower portion of the mantle, which is the asthenosphere, has a temperature of around 4500 degrees Celsius.
Are tectonic plates made of mantle?
The solid portion of the upper mantle which behaves as a brittle solid is known as the lithospheric mantle. This part of the upper mantle along with the crust forms tectonic plates.
What layer of the mantle contains tectonic plates?
The Lithosphere contains the tectonic plates. :)
What is composed lithosphere?
The rigid outermost shell of a rocky planet. Here on Earth, it comprises the crust and the portion of the upper mantle that behaves elastically on time scales of thousands of years or greater.
What is composed of lithosphere?
The rigid outermost shell of a rocky planet. Here on Earth, it comprises the crust and the portion of the upper mantle that behaves elastically on time scales of thousands of years or greater.
Is the lower portion of the crust and the upper portion of the mantle called the core?
It is the Asthenosphere
What is the moving portion of earths crust and upper mantle?
a moving portion of earths crust and upper mantle is called a ridge that's when the ocean floor has underwater volcano that erupts
The lithosphere is composed of the?
The rigid outermost shell of a rocky planet. Here on Earth, it comprises the crust and the portion of the upper mantle that behaves rigidly on time scales of thousands of years or greater.
What do geologists believe heats the upper mantle portion of the asthenosphere?

What name is given to the plastic portion of the upper mantle of the Earth?
This is known as the Asthenospehere.
What part of the mantle is made of soft rock that bends like plastic.?
A portion of the upper mantle known as the asthenosphere.
Which part of earth's mantle is the most solid?
The most outer solid portion of the planet Earth is the crust.
Is the crust a layer of rocks under the plate or is the crust the plates?
The crust is the layer at the surface that forms the upper part of the plates. The plates also include a portion of the upper mantle just beneath the crust. Together, the crust and this upper portion of the mantle form the lithosphere.
