In September, Oza et al. claimed to have found spectroscopic evidence of this process occurring on an as-yet undiscovered exomoon of WASP-39 b. For 10 points each:
[10h] Tidal heating drives what phenomenon that can eject volatile gases and liquid water from the interior of a planet or moon?
ANSWER: cryovolcanism [or cryovolcanic activity; prompt on volcanism or volcanic activity]
[10e] This planet’s moon Enceladus is one of two solar system bodies that are known to be cryovolcanically active. Cryovolcanism may be the origin of a methane haze on Titan, another moon of this second-largest gas giant.
ANSWER: Saturn
[10m] Jupiter’s moon Io is the most volcanically active solar system body because orbital resonance with the other Galilean moons excites its orbit’s value of this quantity. This quantity ranges from 0 to 1 and is about 0.017 for the Earth’s orbit.
ANSWER: eccentricity [prompt on epsilon or e]
