The objects don’t actually touch. http://commons.wikimedia.org/wiki/File:Fireman_employee_ignites_a_prescribed_burn.jpg http://commons.wikimedia.org/wiki/File:Sunburn_(131417495).jpg

Warm fluids rise to the top of the system, where they cool. Cool fluids sink to the bottom near the heat source, where it becomes heated again, causing the cycle to continue. http://www2.chilton.k12.wi.us/sromekg/dynamic_earth_notes.htm
