| Title: | Plate Tectonics and Magma Generation. |
| Caption: | This animation shows two main ways in which plate tectonics is involved in magma generation. The first part depicts magma rising to the surface via decompression melting to erupt at hotspots and divergent boundaries. The second part covers wet melting at an oceanic-oceanic convergent boundary, with the creation of a volcanic island arc. |
