Question

(d) Triton, a moon of Neptune

THANKS

Answer 1

d. Triton...due to the enormous pressures its' mother planet causes on it.  

Answer 2

Io.  Tidal heating from Jupiter and the other moons churns it's insides.

Triton is a moon of Neptune.

Titan is a moon of Saturn.

Answer 3

C.) Io, a moon of Jupiter

Answer 4

Io.  Any picture you'll ever find of the surface is now out of date.

Answer 5

Io is very active.  Mars and the moon are not.  I'm not sure about Triton but I cannot think of any reason why it should be particularly active.  Go with Io.  LOTS of volcanic activity.  

Answer 6

Io, the moon of jupiter

the rest are geologically inactive, and isnt triton a moon of saturn anyway?

Answer 7

(c). Io

Io's extreme geologic activity is the result of tidal heating from friction generated in its interior by Jupiter's varying gravitational pull
