Final answer:
Convergent boundaries are where tectonic plates move together, and these zones can melt rock into magma, leading to volcanic activity as seen in the Pacific Ring of Fire.
Step-by-step explanation:
The tectonic plates are moving together at a convergent boundary, which is the kind of boundary that creates enough friction to melt rock into magma.
A convergent plate boundary is where two plates are moving towards each other. In these areas, subduction typically occurs when an oceanic plate is forced beneath a continental plate or another oceanic plate. The subduction of the plate leads to the formation of deep trenches and can generate magmatic activity as the descending plate heats up and melts. Water released from the subducting plate lowers the melting point of the overlying mantle, aiding in magma formation. This process can lead to significant volcanic eruptions and the development of volcanic arcs, such as those found around the Pacific Ring of Fire. Additionally, convergent boundaries can form significant mountain ranges, like the Himalayas, due to the collision of two continental plates.
