Background You know that the arth’s crustal plates are always moving, but how fast? ach of arth’s plates can move at a different speed and these speeds can change over geological time. But WebMay 21, 2008 · Crust under the oceans is only about 5 km thick while continental crust can be up to 65 km thick. Also, ocean crust is made of denser minerals than continental crust. The tectonic plates are made up of Earth’s crust and the upper part of the mantle layer underneath. Together the crust and upper mantle are called the lithosphere and they ...

WebPlates move away from each other at spreading centers (divergent boundaries). A convergent plate boundary separates plates that are moving toward each other. A transform plate boundary is a fault zone along which two plates slide in opposite directions. Oceanic crust is subducted underneath continents or in oceanic trenches. WebOct 28, 2014 · The Earth's tectonic plates do not move on top of the crust, they are the crust. The crust is made out of plates. The plates float on top of the mantle, which is made of molten rock, called magma ...
