2. Why is the equatorial region warmer (sunlight hits the equator on a straight line most of the year)
3. The earth layers (the crust is like the peal on a peach)
4. Tectonic plates (first video)
5. Earthquakes
6. Continental drift theory (second video)
7. Photosynthesis
8. Trophic pyramid (food chain)
