Quarter 2
Unit 3: Interior Earth
Main Ideas:
- The Earth started out hot because of friction, and it has stayed hot because of radioactive decay
- The Earth can be separated into chemical layers (crust, mantle core) and physical layers (lithosphere, asthenosphere, mesosphere, outer core, inner core)
- Convection Currents in the mantle are responsible for the movement of Earth's crust

Unit 4: Plate Tectonics
Main Ideas:
- In the 1900s, a scientist suggested that the continents use to be one, single land mass. Fossil evidence supported this.
- After 1950, evidence from the bottom of the ocean confirmed that the continents are moving
- Mantle plumes tell us which direction a tectonic plate is moving
Main Ideas:
1. The plates move because of convection currents
2. There are three types of plate boundaries: convergent, divergent, and transform
3. When the plates move they change the surface
