I'm currently having a heated argument with family members over this question:
If I was to travel to centre of the Earth, would you die from heat or cold first?
My answer would be cold, as anyone would realise if they have been caving before, the temperature decreases significantly hence stalagmites & stalagtites. the reason people keep wine in their cellar is because it is cool/cold. When you go deeper you see caves with icicles from the ceiling. I believe it gets progressivly colder the further down you go. I do believe at some stage it will heat up when nearing the molten lava that is in our earth but I remain positive that I am right.
Any help or links to prove my theories are most welcome.
