It is called a divergent plate boundary.
A volcano will form at the boundary of two plates moving apart. This is because the two plates moving apart create a crack allowing molten lava to flow up from the mantle.

Convergent: plates move into one another.Divergent: plates move apart.Transform: plates move sideways in relation to each other.
A divergent plate boundary is one where the two plates on either side of the boundary are moving apart; 'di-' meaning away. Convergent plates are moving together.
Divergent Boundaries - A boundary between two lithoperic plates that are moving apart .

divergent boundary
When two plates are pulling apart, it is known as divergent boundary or divergent plate boundary. This type of boundary results in the formation of new crust as magma rises to the surface and solidifies.
A divergant plate boundary.
Tensional boundary is the meeting zone of two tectonic plates at a normal fault; the plates move apart

A divergent plate boundary lies between two plates that are moving away from each other. At these boundaries, new crust is created as magma rises up from below the Earth's surface and solidifies, pushing the plates apart.
