Outline

 * Science of Geology
 * studying surface changes
 * surface always changing
 * finding indirect evidence
 * cannot see inside earth
 * use seismic waves
 * speed of waves tells the material


 * Center of the Earth
 * temperature
 * surface rock is cool
 * 20 meters/warmer
 * every 40 meters 1 degree celsius hotter
 * boy that's hot
 * pressure
 * deeper you the greater the pressure


 * The crust
 * continental
 * granite
 * light colored rock
 * oceanic
 * basalt


 * The mantle


 * The core
