Solution 1
| Crater | Caldera |

Solution 2
Crater and Caldera: Crater forms the summit and Caldera the enlarged mouth or the sunken crater at the center of a volcano. When water accumulates in a crater it forms a crater lake and in a caldera a lake like Taba lake of Sumatra. A crater is formed as a result of the overflow of lava and calera as a result of subsidence.
