It extends from below the mantle to the center of the earth. Scientists think thats it made mostly of iron and somenickel, and that it has much less oxygen, silicon, aluminum, and magenesium than the mantle does
Is the movement of matter that results from differences in density caused by variations in tempature.
About 245 million years ago, the continents were joined in a single large landmass called pangea. As the continents collided to form pangea, mountains formed.
to explain age and magnetic patterns of sea-floor rocks, scientists proposed a process, in his process, molten rock from inside earth rises through the cracks in ridges,cools, and forms new oceanic crust
describing large-scale movements of the Earths lithosphere, which is made up of the crust and the rigid, upper part of the mantle. Explains how and why features in earths crust form and continents move
Form when 2 plates collide. Three types of collisions can happen.
two plates move away from each other, this seperations allows the asthenosphere to rise toward the surface and partially melt.
boundary at which two plates move past each other horrizontially. However, plates do not slide along smoothly, nut, instead, they scrape against each other in a series of sudden slipages of crustal rock that are felt as earthquakes
any place where gas, ash, or melted rock come out of the ground.
melted rock, less dense than solid rock, so it rises toward the surface.
