Question

Which statement about Io is true?

a.It is the only moon in the solar system with a thick atmosphere.
b.It is the largest moon in the solar system.
c.It is the most volcanically active body in our solar system.
d.It is thought to have a deep, subsurface ocean of liquid water.

Answer 1

Io is the most volcanically active body in our solar system, experiencing intense volcanic activity due to Jupiter's tidal heating.

Step-by-step explanation:

The statement about Io that is true is that it is the most volcanically active body in our solar system. Despite its similarity in size and density to our Moon, Io is incredibly volcanic due to the intense tidal heating caused by Jupiter's strong gravity. This gravity stretches Io and generates heat, leading to its extreme volcanic activity. While Ganymede is actually the largest moon in the solar system, and Europa is the moon with strong evidence pointing to a subsurface ocean of liquid water, Io is distinguished by its remarkable geologic dynamism.
