What are the earths plates floating on?
The surface of the Earth is divided into roughly 30 separately distinct units called plates. Each individual plate is separated by a fault, and each plate moves independently of every other plate. The movement, or float, of the lithospheric plates is caused by heat from the Earth's interior, which causes convection currents in the Earth's mantle, a layer of solid but movable plastic-like rock. The movement of Earth's lithospheric plate which 'float' on the mantle is very slow in human terms, roughly the rate of fingernail growth, but over millions of years, the change in plate locations is dramatic.
What does the crust float on?
The crust rides or floats on the mantle. :)
Why are continents not fixed permanently in location on the earths crust?
The continents are embedded in the top side of crustal plates which float on the surface of the mantle. Convection currents in the mantle carry the plates around and the embedded continents travel along.
What area has huge slabs of rock that float on the mantle?
tectonic plates
What area of the earth's layers is made of huge slabs of rock that float on the mantle?
Crust
What layer do the lithospheric plates float around on?
Asthenosphere
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)
Explain how plate tectnonics and why they occur?
Lithospheric plates made up of the upper mantle and crust float on the soft, flowing aesthenosphereand are moved around by the flow of the aesthenosphere caused by convection from the core.
How can you describe the seven crustal plates?
There are actually at least 31 identified lithospheric plates, the plates consisting of crust and uppermost mantle which float on top of the plastic-like asthenosphere of the mantle.
What is lithospheric plate movement?
The lithosphere is the solid part of the Earth's surface, the crust and uppermost mantle, which is fragmented into plates which "float" over the hotter, more fluid asthenosphere.

Why do the plates float on the mantle?
Tectonic plates float on the mantle because they are less dense
Do the plates float on the mantle?
Tectonic plates float on the mantle because they are less dense
Tectonic plates float on a layer of the earth called the?
The outer layer of the earth where the land masses are is called the crust
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.
What does the crust float on?
The crust rides or floats on the mantle. :)
What do plates float on?
Upper mantle
