1 How is magma generated along convergent plate boundaries?

Friction from the subducting plate raises the temperature of the rock under which it subducts, melting this rock into magma.
The subducting plate pushes mantle rock upwards, where it reaches the surface through the trench.
The subducting plate drives water and carbon dioxide into the mantle, which reduces the temperature at which it melts, allowing mantle rock to melt and rise.
The collision of two continental plates create enough heat to melt rock, thus producing magma.
The subducting plate pushes mantle rock upwards, which decompresses as it rises. This decompression allows the mantle rock to melt.

Volcanism at divergent plate boundaries is most often associated with which rock type, and what causes rocks to melt in these settings?

Volcanism at divergent boundaries is most often associated with felsic rock, which is created by decompression melting.
Volcanism at divergent boundaries is most often associated with basaltic rock, which is created by heating of the crust.
Volcanism at divergent boundaries is most often associated with basaltic rock, which is created by water lowering the melting temperature of mantle rock.
