They float on the heavier, semi-molten rock of
the mantle
They collide with and separate from each other.…read more

Where plates collide
1. Currents of molten rock in the earth's
mantle drag the plates slowly towards each
Deep ocean trenches (valleys) might occur
where one plate is pulled under the other.
Fold mountains are formed.
Earthquakes happen.…read more

Where plates separate.
1. Currents of molten rock in the Earth's
mantle slowly drag plates apart from each
2. Where the plates separate, volcanic
material rises up from the mantle to form
volcanic island, volcanic mountains and long
mid-ocean ridges.
