| Description | The earth is made up of four layers – the inner core, outer core, mantle and crust. The mantle and crust are a thin skin compared to the other layers. The mantle is about 1,800 miles thick, while the crust is only about 8 miles thick. This thin skin is broken into pieces called tectonic plates. The plates are like puzzle pieces, floating on top of the Earth’s inner core. Sometimes the pieces slide under or against each other and become stuck.When the pieces slide apart, they create tremendous force. This force causes the earth to shake and ripple. |
