A Deep Valley That Forms Where Two Plates Move Apart
This allows the plates to move. Earthquakes volcanoes mountains and deep ocean trenches can all form this way.

The movement of these plates is known as plate tectonics.
. Divergent plate boundaries describe the scenario in which two tectonic plates move apart from each other. Magma seeps upward and solidifies making new crust on the plates edges. Most tectonic activity takes place at the boundaries of these plates where they collide tear apart or slide against each other.
The magma becomes a kind of rock called basalt which is found underneath the ocean floor. These boundaries are often volatile with lava eruptions and geysers along these rifts. Tectonic activity is responsible for many geologic events.
