Vocabulary

 * Earthquake**:shaking/trembling of rocks underneath Earth's surface
 * Stress**:the force that acts/pushes on a rock to change it
 * Shearing**:form of stress that pushes two large pieces of rock in opposite directions
 * Tension**:form of stress that pulls apart a rock so that the middle is thinner than that of the sides/edges
 * Compression**:form of stress that squeezes rock until it folds or breaks
 * Deformation**:change of volume or shape in Earth's crust
 * Fault**:a place where two rocks have slipped past each other
 * Strike-slip Fault**:a fault where two rocks have slipped past each other with very little to no up-down motion
 * Normal Fault:** a normal fault is at an angle, so that one side is on top, and the other is on the bottom
 * Reverse Fault**:similar structure to a normal fault except for that they move differently
 * Fault-block mountain:** A mountain that forms where a normal fault lifts a block of rock.
 * Fold:** A bend in rock that forms where part of the Earth's crust is compressed.
 * Anticline:** A fold in the rock that bends upward
 * Syncline:** A fold in the rock that bends downward
 * Plateau:** A large area of flat land elevated high above sea level.
