Best Answer

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.

No. The plates are made of lithosphere, which consists of the crust and the uppermost part of the mantle. The asthenosphere is the layer below this.

About the asthenosphere?

The asthenosphere has the ability to slow down seismic waves. Is not made up of earths plates that would be the lithosphere.


What are the 2 parts of the lithospheric plates?

The lithospheric plates are made up of the crust and the uppermost part of the mantle. These plates float on the semi-fluid asthenosphere beneath them.


The earths crust is made of rock sections called?

Continental plates.

What best describes what earths plates are made up of?

Earth's plates are made up of the rigid outer layer of the Earth's surface, known as the lithosphere. The lithosphere is composed of the Earth's crust and the uppermost part of the mantle. These plates float on the semi-fluid asthenosphere layer beneath them, which allows for the movement of tectonic plates.


What are the three layers of the mantle?

Lithosphere is the layer clostest to the earths crust. It is the layer that contains the sial and sima. Asthenosphere is the next layer clostest to the earths crust. Mesosphere is the inner most layer of the mantle than it goes to the core... Outer core, and inner core


What makes up the earths lithosphere?

The Earth's lithosphere is made up of the crust and the uppermost part of the mantle. It is divided into several large and small tectonic plates that float on the semi-fluid asthenosphere below. These plates interact at plate boundaries, where geological activities like earthquakes and volcanic eruptions occur.


What type of crust is the earths tectonic plates made up of?

The Earth's tectonic plates are made up of the lithosphere, which consists of the crust and the upper part of the mantle. The crust is primarily composed of solid rock made up of elements such as oxygen, silicon, aluminum, and iron.


What is earths lithosphere made out of?

The Earth's lithosphere is primarily made up of the Earth's crust and the upper part of the mantle. The crust is composed of various types of rocks, such as basalt and granite, while the upper mantle consists of solid rock material. The lithosphere is divided into several large tectonic plates that float on the semi-fluid asthenosphere below.


What is a rigid layer made up of the crust and the upper part of the earths mantle?

the Lithosphere or Lithospheric Plates


Does tectonic plates move on lithosphere?

Yes, tectonic plates move on the lithosphere. The lithosphere is the rigid outer layer of the Earth that is made up of the crust and the upper part of the mantle. Tectonic plates float and move on the semi-fluid asthenosphere layer beneath the lithosphere.


What layer of the earth makes up theses plates?

The Earth's lithosphere is comprised of the tectonic plates that float and move on the semi-fluid asthenosphere beneath them. These plates are made up of the crust and the upper part of the mantle.
