Vocabulary

 * stress**: a force that acts on rock to in the crust to change its shape or volume
 * earthquake**: a shaking movement that results from movement of rock beneath Earth's surface.
 * shearing**: a type of stress that pushes a mass of rock in two opposite directions.
 * tension**: a type of stress force that pulls on crust, stretching rock so it's thinner in the middle.
 * compression**: a force that squeezes rock together until it folds or breaks.
 * deformation**: any change in shape or volume in Earth's crust.
 * folds**: bends in rock that form when compression shortens and thickens a part of Earth's crust.
 * anticline**: an anticline is a fold in rock that bends upward into an arch.
 * syncline**: a syncline is a fold in rock that bends downward into an valley.
 * plateau**: a large area of flat land elevated way above sea level.

Types of Stress

 * shearing
 * the stress that pushes mass of rocks into two opposite directions
 * tension
 * the stress force that pulls on the crust, stretching rock so that it becomes thinner in the middle
 * compression
 * the stress force that squeezes rock until it folds or breaks

Kinds of Faults

 * Strike-slip fault
 * two rocks slip past each other in a sideways, up, or down motion.
 * Normal fault
 * the fault is at an angle so one block of rock lies above the fault when the other is below the fault.
 * Reverse fault
 * same structure as a normal fault, but the blocks move in opposite direction.

Mountain Building

 * Mountains formed by faulting
 * fault-block mountain
 * Mountains formed by folding
 * Himalayas
 * Alps
 * anticlines and synclines
 * anticline
 * The fold in a rock that bends upward into an arch
 * syncline
 * The fold in a rock that bends downward in the middle to form a bowl
 * Plateaus
 * Plateaus are large areas of flat land that are elevated way above sea level
 * Now a days, there are lots of the plateaus that are more than 1,500 meter above sea level
