 * An earthquake is caused by the movment of two large plates around the surface of the earth. As plates move, the rocks on their edges change shape and take up strain until at the weakest point of the plate, the fault, breaks away.**
 * Plates move because of the strong heat in the Earth’s core. This causes melted rock in the mantle layer to move. It moves in a pattern that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again.**
 * Plates have warmer, thinner parts that are more likely to rise, and colder, thicker parts that are more likely to sink.**
 * New parts of a plate rise because they are warm and the plate is thin. Old parts of a plate are likely to sink down into the mantle layer cause they are colder and thicker than the warm man﻿ tle material underneath them.**

3. How deep do cracks go ﻿under the﻿ earth? 4. How far can earthquakes spread? ﻿ 2. How do aftershocks occur?
 * The crackes can go upto 5km underground. **
 * Week 8 questions **
 * ﻿Aftershocks usely happen afew days after the earthquake has happened. The earth shakes and so afew dayes after the earthquakes happens you will usely feel a aftershock. It feels like another earthquake but is really just a shock. **
