1. Earthquakes can strike any location at any time, but history shows they occur in the same general patterns year after year, principally in three large zones.
2. Plate tectonics is a scientific theory describing the large-scale motion of the plates making up the Earth's lithosphere since tectonic processes began on Earth between 3.3 and 3.5 billion years ago.
3. Anticlines are folds in which each half of the fold dips away from the crest. Synclines are folds in which each half of the fold dips toward the trough of the fold.
4. Mountains are divided into four main types: upwarped, volcanic, fault-block, and folded (complex). Upwarped mountains form from pressure under the earth's crust pushing upward into a peak. Volcanic mountains are formed from eruptions of hot magma from the earth's core.
5. Volcanic earthquakes are one of the main signs that a volcano is restless. Tectonic earthquakes are caused by the movement of plates when energy accumulated within plate boundary zones is released.
