I read a recent article (pc magazine) that said the Earth is currently generating 44 terawatts of heat with 23 terawatts comign from radioactive decay (8 from uranium, 8 from thorium, and 4 from potassium). Given this, and that the Earth is 4.5 billion years old...how many more terawatts were coming from radioactive decay at 2 billion and 4 billion years ago?
What sort of affect would this have had on life and the continents moving?
