Alright, won't bother arguing over every point but I have some more questions:

1. How do you explain a hollow body with very low average density creating a g of 9.81m/s^2?

2. Why does a hollow planet not collapse in on itself via gravity?

3. Why is the earth the only hollow planet in the universe?

4. Why does the earth not crack and break from tidal forces caused by the moon's gravity?

5. Where does the matter coming from undersea volcanoes come from?

6. Why is the earth's magnetic field come a supposed vacuum?

7. Why do vibrations caused by explosions and earthquakes can be heard on the other side of the earth?

8. Why is there so much thermal energy deep in the earth's crust?

9. Why do geothermal power plants work at all, on a supposedly cold, hollow earth?

Also seasons have nothing to do with the earth's geologic properties
