地慢內岩漿的對流作用怎樣影響板快移動??

There are radio-active materials in the core. It releases energy to heat up magma and causes convection current of magma. The plates are then moved because of the convection current of magma.
The plates are moved in different ways. The plates move towards and collide with each other(destructive plate boundaries), depart with each other(constructive plate boundaries) and silde part one another(conservative plate boundaries).
