Final answer:
Magma is generated as a result of the addition of water to rock in convergent plate boundaries.
Step-by-step explanation:
Magma is generated as a result of the addition of water to rock in convergent plate boundaries. When two tectonic plates converge and one of the plates subducts beneath the other, the subducting plate contains hydrated minerals that release water. This water lowers the melting temperature of the mantle region above the subducting plate, leading to magma generation.
