a diagram that shows what the inside of something looks like

moving apart in different directions

a sudden shaking of Earth's surface

evidence of life from the past, such as fossilized bones, footprints, or leaf prints

a feature that forms on the surface of a planet, such as a mountain, channel, coastline, or sand dune

hot liquid rock below the surface of Earth

the layer of soft, solid rock underneath Earth's surface

an underwater mountain range formed when two plates move apart

an object, diagram, or computer program that helps us understand something by making it simpler or easier to see

Pangaea is a theoretical ancient supercontinent that existed millions of years ago… This supercontinent includes all current land masses (continents, islands, etc.) as one huge continent…. Meaning the continents all once made up one piece of land together.

something we observe to be similar over and over again

a large section of hard, solid rock that makes up Earth’s outer layer

the place where two plates meet

lowland region that forms where continental and continental plates move apart

when two plates move towards each other, the more dense plate bends under the less dense plate, curving down into the mantle; this process forms deep ocean trenches

a long, deep indentation in the ocean floor formed when two plates move together

two plates grind against each other in opposite directions

As two plates move towards each other, one tectonic plate moves up and over another piece of more dense crust; this process causes mountain ranges

___________ is semifluid while __________ is completely fluid.
