In Response To: Re: Yes, Mage, radioactive decay (OT) (Mark Levin) Intense heat from the inner core is continually radiated outward, through the several concentric shells that form the solid portion of the planet. The source of this heat is thought to be energy released by the radioactive decay of uranium and other radioactive elements. Convection currents within the mantle transfer most of this heat energy from deep within the earth to the surface and are the driving force behind continental drift. Convective flow supplies hot, molten rock to the worldwide system of midocean ridges (see Ocean and Oceanography) and feeds the lava that erupts from volcanoes on land.

This was no fun at all :) So geological chaos is all caused by radioactives.... Still, pressure is the main driving force on most worlds and stars... "Win a few, lose a few..." |
