Answer:
magma doesnt form at transform boundaries, but it does form at divergent and convergent bounderies.
Explanation:
The divergent boundaries pull apart from each other creating a weak spot in the crust, allowing magma o come through and reach the surface. Some of the rock above the subducting plate melts and forms magma. Because the magma is less dense than the surrounding rock, it rises to the surface.
At convergent boundaries magma is formed where water from a subducting plate acts as a flux to lower the melting temperature of the adjacent mantle rock
i hope this helps a little bit (:
