Document Summary

Dislocation creep when you squeeze the sides of a cube, it extends. Continental crust rocks are less dense than the oceanic crust. Oceanic crust rock that has just been extracted by the mantle. Lithosphere is the rock which is a strong solid. Where earthquakes (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) on the top and the bottom because the atoms and molecules will move. (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) occur. (cid:1) (cid:1) (cid:1) mantle. Canada (ice age) as an example. (cid:1) (cid:1) Continents move up and down because of the flowing rock on the. Continental drift can be proved by fossils found on multiple continents even though they are spread apart. (pangaea one big continent) Convection cells drive the movement of tectonic plates. Transform faults- the plates are sliding beside each other. Movements of the rigid plates are seen on the ground as individual faults. Epicenters outline tectonic plates transform fault plates are shallow.
