Continents moved slowly to their current location?
This is called continental drift, and it is caused by convection currents in the Earth's mantle.
What happens when buoyant mantle material gets near earths surface?
The buoyant mantle material will not subduct under Earth's continental crust. Instead, it will form mountains.
What layer of earth forms the continents?
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
Continents float on the Earth's mantle because continental rocks are than sea floor rocks?
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/cm3basalt = 3.0 g/cm3
What process causes earths plates to move?
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.
Where would you be most likely to find granite in earths mantle or earths continents?
you will find it in earths mantle because it is a kind of an igneous rock
Do continents drift slowly on earths upper mantle or earths core?
Continents drift on top of the upper mantle. The core is much further down.
Why do seismic waves speed up beneath the surface of continents?
Because earths crust is denser than the mantle
Why do the earths continents float on the liquids mantle of the earth?
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.

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 layer is the thickest of earths crust?
The answer is Continental crust.The Mantle is the thickest layer of the Earth. :)
What is the part of the earth which the tectonic plates are able to move?
The mantle moves the continents, which is called continental drift.
What layer are the continents sliding down?
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.
Continents moved slowly to their current location?
This is called continental drift, and it is caused by convection currents in the Earth's mantle.
Where was the continental drift?
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.
Which layer of the earth is thought to be responsible for continental drift?
simple....the answer is mantle.(: Glad to help!
What happens when buoyant mantle material gets near earths surface?
The buoyant mantle material will not subduct under Earth's continental crust. Instead, it will form mountains.
