Vocabulary

 * Earthquake**: the shaking and trembling that results from the movement of rock beneath Earth's surface


 * Stress**: a force that changes the rocks shape and volume


 * Shearing**: the stress where rocks slide past each other at opposite directions, sideways, releasing energy


 * Tension:** the stress where rocks pull at different directions, causing the rock in the middle to stretch to its thinnest


 * Compression:** the stress where rocks squeeze until the rock either bends or breaks


 * Deformation:** any change of volume or shape of Earth's crust


 * Fault:** a break in Earth's crust where slabs of stone slip past each other


 * Strike-Slip Fault:** where two slabs of rock slip past each other in sideways or little up and down motion


 * Normal Fault:** one half of the fault is on top while the other on the bottom


 * Hanging Wall:** the half of the fault that lies above


 * Footwall:** the half of the fault that lies below


 * Reverse Fault:** same structure as a normal fault but the blocks move in opposite directions


 * Fault-Block Mountain:** when normal faults uplifts a slab of rock


 * Folds:** bends in rock that are formed by compression


 * Anticline:** a fold in rock that bends upward into an arch


 * Syncline:** a fold in rock that bends downwards into a bowl


 * Plateau:** a large area of land that is elevated high above sea level
