earthquakes
the plates move apart
when the earths plates move we either have earthquakes, tsunamis, and we get ridges and trenches.
tectonic plates move apart allowing magma to move to the surface.
when two plate moves apart from each other the intrusion of magma has been take place from mantle
Plates move apart on divergent plate boundaries.
from plate tectonics
Yes they do.
plate tectonics
A few centimeters a year.
Plate tectonics are what each continent is on. They move and are continuing to move today. It has to do with the earth's shape because the plate tectonics move the continents around.
Well, when earths plates move away from each other that's when it happens but move well then NO!
divergent plate boundaries do.
