An earthquake is a shaking of the ground caused by the sudden shifting of large sections
of the earths crust. Earthquakes are one of the most powerful events on earth, and they can be
terrifying. A severe earthquake may release energy 10,000 times as great as that of the first
atomic bomb. Rock movements during an earthquake can make rivers change their direction.
Earthquakes can trigger landslides and Volcanoes that cause great damage and loss of life.
Large earthquakes beneath the ocean can create a series of huge, destructive waves called
tsunamis.
Plate Tectonics
A plate is a large section of the earths crust. Tectonics is the art or science of making
things out of smaller pieces. According to sceintists, sevn to twelve large plates, and several
smaller ones, make up the earths crust.
The earths plates are continually moving, perhaps as much as several inches a year. As
they move, they bump against each other. They can spread apart from each other, or push
against each other. Somethimes, during this movement, one platre will com up over the top of
another. In other places, two plates will slide along next to one another.
The area of the crust that breaks is known
