The machine that detects the vibrations (seismic waves) in the earth that come from earthquakes
The solid, outer layer of the Earth which we walk on that consists of the crust and the rigid upper part of the mantle
A moving block of lithosphere that consists of the crust and some of the upper mantle
The "plastic" layer of the mantle under the lithosphere on which the tectonic plates move
The single "super" continent that existed 245 million years ago (The name means "all earth" in Greek)
The hypothesis that states that the continents once formed a single landmass, broke up, and drifted to their present locations
Person who looked at the continents and said that they fit together like a puzzle. He proposed the idea of continental drift.
The magnetic poles change places through the course of history and this is recorded in the rocks
An example of a divergent boundary where new oceanic crust forms as magma rises toward the surface and solidifies under the ocean
The boundary between tectonic plates that are sliding past each other horizontally
The boundary that is formed when two tectonic plates slide toward each other...."Come together"
The theory that explains how large pieces of the Earth's outermost layer, called tectonic plates, move and change shape
Hot rock from deep within the Earth rises while cooler rock near the surface sinks
The boundary between two tectonic plates that are moving away from each other..."My poooooor dog"
