  2. 2. drift The hypothesis that a single large landmass broke up into smaller land masses to form the continents, which then drifted to their present locations; the movement of continents
  3. 3. tectonics The theory that the earth's outer layer is made up of large, moving pieces called tectonic plates.theory system of ideas that explains many related observations and is supported by a large body of evidence acquired through scientific investigations new oceanic lithosphere forms when magma rises to the earth's surface
  4. 6. The solid, outer layer of earth that consists of the crust and the rigid upper part of the mantle
