lighter continental rock (mainly granite) is less dense than mantle material.
continental rock is also less dense than oceanic crust (basalt) but sea floor rocks are not the same thing as mantle material.
granite = 2.7 g/cm3
basalt = 3.0 g/cm3
Continental rock is less dense than mantle rock.
This is called continental drift, and it is caused by convection currents in the Earth's mantle.
The buoyant mantle material will not subduct under Earth's continental crust. Instead, it will form mountains.
the crust. the layer below that is the layer of molten lava called the mantle. the continental plates move and float on this. this is known as continental drift
The process of 'earth plates moving' is Alfred Wageners theory of continental drift. This theory proposes that convenction currents in the earths mantle provides a 'cushion' on which the plates can move.
you will find it in earths mantle because it is a kind of an igneous rock
Continental rock is less dense than mantle rock.
Continents drift on top of the upper mantle. The core is much further down.
Because earths crust is denser than the mantle
The continents "float" on the liquid mantle of the Earth because the metals that make up the mantle are very dense. The continents move when magma is pushed through the crust of the Earth in places like the Mid-Atlantic Ridge.

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.
The answer is Continental crust.The Mantle is the thickest layer of the Earth. :)
The mantle moves the continents, which is called continental drift.
The continents are located on Continental plates, which "float" and "slide" along the Asthenosphere, which is the "gooey" upper mantle and lower part of the crust.
This is called continental drift, and it is caused by convection currents in the Earth's mantle.
Continental drift occurs under the earths crust by convection currents in the mantle which drives the plates. It has been happening since the development of the earths core and is happening now and until the end of the earth.
simple....the answer is mantle.(: Glad to help!
