Draw raw molten rock to the surface and make it flow as though it has purpose. It deals 4d6 fire damage to each creature in a 25' line up to 50' that fails a Constitution save and half this on a success. Creatures that end their turn in this area reroll the save. This lava ignites all unattended objects, and plants in it's path. The line for the flow can increase to 300' if cast down a steep incline and may change course at the DM's discretion.

Other Planes and Effects
Below is information about this spell as it relates to other planes and area of effects (i.e. underwater). Some of the information is pulled official D&D sources (such as books and the twitter feeds of D&D officials), but other information is derived from forums and online discussions. As always, it is up to the DM to decide how they wish to handle spell effects.
Underwater - Verbal Component
Official rules have been verified by Jeremy Crawford - "No rule prohibits verbal components from working underwater. Keep in mind that if you're talking, you're not holding your breath." Hence, while submerged underwater and holding its breath, a creature can cast a spell that requires a verbal component. After casting the spell, if the creature can't breathe underwater, it immediately runs out of breath. The creature can survive for a number of rounds equal to its Constitution modifier (minimum of 1 round).
Underwater - Fire Effects
The PHB p198 clearly states "Creatures and objects that are fully immersed in water have resistance to fire damage." Other than that, there are no official rules regarding fire spells underwater. But, as always, it is always up to the DM to decide if fire spells should have different effects (i.e. half range, half area of effects, half duration, etc.). In addition, Jeremy Crawford has clearly stated, regarding a fireball vaporizing water, "Nothing in the rules causes a fireball to vaporize water. Magic ≠ physics. DMs may apply whatever magical/scientific logic they like."
