We lack the knowledge which it would take to answer that question correctly.
Convergent and divergent boundaries melt rock in the upper mantle while transform boundaries do not. Convergent boundaries that involve at least one oceanic plate form subduction zones, where an oceanic plate plunges into the mantle. Volatiles carried into the mantle lower the melting point of the rock there, allowing magma to form.At divergent boundaries the crust becomes thinner. This reduces pressure on the upper mantle, thus lowering melting points and generating magma.Transform boundaries have no such means of producing magma.
Divergent plate boundaries occur where two plates are moving away from each other, and "new ground" is being formed. The oceans all have divegent boundaries at the mid-oceanic ridges. Another one is in eastern Africa in what is known as the Great Rift Valley. This will someday split the African continent apart.
It forms at the edges of Divergent Tectonic Plates; as opposed to the Earthquakes that are found at the Convergent Plate Boundaries [where one Plate subsides beneath the other Plate].
When plates diverge, the crust in between them is pulled thin. This tension creates a rift valley, such as the one found between the two islands of New Zealand. Over time, the stretched crust with grow so thin that rising magma will break its surface, forming an underwater ridge.
90% of volcanic activity on earth occurs at either convergent or divergent plate boundaries. The remaining 10% occurs at hot spots, which are not associated with plate boundaries.
Shearing stress is one of three kinds of stresses. Compressional and tensional are the others. Shearing stress is associated with transform. The other two kinds of plate boundaries are convergent and divergent.
The four types of plate boundaries are divergent boundaries (plates moving apart), convergent boundaries (plates moving together), transform boundaries (plates sliding past each other), and subduction zones (one plate sinking beneath another).
The difference between transform and divergent boundaries is that transform boundaries occur when tectonic plates slide past each other, whereas at divergent boundaries they move away from each other. However in both cases the plates move horizontally (unlike at convergent boundaries where one plate may be pushed underneath another).
divergent
Divergent, one of the three Plate boundaries.
Volcanoes are commonly found along convergent plate boundaries, where one tectonic plate is forced beneath another in a process called subduction. They can also be found along divergent plate boundaries, where tectonic plates are moving apart and magma rises to fill the gap, creating volcanic activity.
A rift boundary is a divergent boundary, where two plates of the earth's crust are moving away from each other. Divergent boundaries occur at mid-oceanic ridges on the sea floor, but usually the term rift is used to describe divergent boundaries on the land. The best known one is in eastern Africa.
Most volcanoes form at either convergent or divergent plate boundaries. Volcanoes at convergent plate boundaries form when one plate slides under another, taking seawater with it. This causes the rock in the mantle to melt as the melting point drops. This new magma can rise to form volcanoes.At divergent plate boundaries the crust is thing, which lowers pressure on the mantle, causing some material to melt.
divergent plate boundary- a boundary where two plates move apart from each other. convergent plate boundary- a boundary where two plates move towards each other so that one plate can sink beneath the other. transform plate boundary- a boundary where one plate slips along side another plate.
Convergent and divergent boundaries melt rock in the upper mantle while transform boundaries do not.

The mid-ocean ridge is almost in all of the oceans
Divergent boundaries because the plates are going away from one another.
