Web21 mei 2008 · Plates at our planet’s surface move because of the intense heat in the Earth’s core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again. http://www.columbia.edu/~vjd1/subd_zone_basic.htm how many world cups has france won in soccer
