how do a convection current work?

warm rises, cools, sink down,cools sinks down,warms,rises up, I'm lost

what is continental drift?

gradual movement of the continents across earths surface

what is a transform boundary?

where plates change directions, where plates slide sideways past each other

plate moves farther from the ridge and cools

what is a ridge push?

push from the crest towards subduction zone
