What layer of the mantle contains tectonic plates?
The Lithosphere contains the tectonic plates. :)
Are plates made of Earth's crust and asthenosphere?
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.
Which layer of the earth contains the tectonic plates?
The plates are part of the crust, the upper layer of the Earth. The plates are moved by currents in the upper mantle. The plates and flexible upper mantle are referred to collectively as the lithosphere and sit atop the mantle layer called the aesthenosphere.
What layer of earth contains the tectonics plates?
The layer of the earth that allows the tectonic plates to move around above it is the mantle. The mantle is also known as the hot molten magma layer called the asthenosphere.
Is the lower portion of the crust and the upper portion of the mantle called the core?
It is the Asthenosphere
Where does crustal plates float?
the plates float on top of the upper mantle
What do plates float on?
Upper mantle
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.
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.
What layer of the mantle contains tectonic plates?
The Lithosphere contains the tectonic plates. :)
What are earth's tectonic plates?
Sections of Earth's crust that "float" over the upper mantle.
Do tectonic plates 'float' on the surface of the mantle?
The tectonic plates (the lithosphere) are made of the crust and upper brittle part of the mantle. They 'float' on the hotter and softer mantle below, which is still a solid, but can flow like plasticine (the asthenosphere)
Which of earth's layers contains soft areas on which plates float?
Earth's surface I might be wrong I am only 9
Are plates made of Earth's crust and asthenosphere?
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.
What is the theory that Earth's crust and upper mantle are broken into plates that float around and move on a plastic like layer of the mantle?
It is the theory of plate tectonics.
Do the plates that make up the crust float on molten rock of the mantle?
Technically, no. They float on top of the asthenosphere, a layer of the upper mantle which is solid, but plastic in nature due to intense heat and pressure.
On 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.
