- 1Wegener proposed this hypothesisContinental Drift
- 2Each of the rigid slabs of Earth's lithosphere is called aPlate
- 3The mechanism responsible for producing new sea floorSea floor spreading
- 4The type of plate boundary where plates move togetherConvergent plate boundary
- 5Ancient magnetism in rock structuresPaleomagnetism
- 6This theory states that Earth's crust consists of 7 smaller sectionsPlate tectonics
- 7When rocks exhibit the same magnetism present in the magnetic fieldNormal polarity
- 8The type of plate boundary where plates move apartDivergent plate boundary
- 9A rising plume of magma such as the one that created the Hawaiian islandsHot spot
