Which option below best describes how the flow of heat through the mantle affect the movement of the Earth's tectonic plates?
heat is transferred from the mantle to the curst by radiation which then causes the plates to move on the surface
earth's tectonic plates move due to the graviational pull at eath's core and the flow of heat due to conduction in the mantle
in thematle heated materal cools and becomes less dense as it rises to the surface froming a heated cell which causes the crust to harden and move the plates
in the mantle heated materical expandes and rises towards the crust where it then cools, becomes denser and sinks, forming a convection current which casues plate motion

diverging
converging ocean and contiental
converging continental and contiental
transform
