EarthquakesEarthquakes
A shaking of the earth’s crust due to a release of energy

OccurrencesOccurrences More than 3 million occur each
year About 8,000 per day, or 1
every 11 seconds Most are extremely weak There are three major
earthquake zones:

Major Earthquake ZonesMajor Earthquake Zones
Most earthquakes occur along the edges of the earth’s lithospheric plate boundaries

BoundariesBoundaries
Divergent: Two plates are moving away from each other
Sea floor spreading

BoundariesBoundariesSubducting:On plate is forced under another
This is a type of
convergent boundary!
