new rock is forming
what do scientist believe is happening to the segments of the earths crust
it has been washed into the oceans as the continental crust has eroded.
The mantle under the Earth's crust, the sea and the Earth's crust.
New crust is being formed.
they believe that the earth is moving
Answer this question… Subduction of oceanic crust beneath continental crust
Lots of things. Most of which are leading to the creation of new oceanic crust.
Most certainly. They've been happening since the crust formed.
It's happening RIGHT NOW, right under your feet. The movement of tectonic plates is so slow that you have no idea it's happening, but the earth's crust is very dynamic.
Mountains form and push apart the Earth's crust.
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.
By the convection processes happening in the mantel and by is own density (it is cold rock) with respect to the rest of the mantle.
