Convection currents take place in the mantle and result when less dense material rises closer to the crust and dense material sinks back into the mantle. As the less dense material rises, it causes plate tectonics.
plate movements :
collide making mountains
pull apart making volcanoes
slide past each other making earthquakes
analogy :
plate tectonics is like
a raft floating on water
plates are like rafts
raft moves on water
convection currents in the mantle are like water
