What is the difference between a terrestrial moon and a gas giant moon?

Moons are natural satellites that orbit planets in our solar system. There are two main types of moons: terrestrial moons and gas giant moons. Terrestrial moons are small and rocky, while gas giant moons are large and composed mostly of ice and gas.

The main difference between these two types of moons is their location. Terrestrial moons are found orbiting the terrestrial planets in our solar system: Mercury, Venus, Earth, and Mars. They are typically small and have low gravity. Gas giant moons, on the other hand, are found orbiting the gas giant planets: Jupiter, Saturn, Uranus, and Neptune. They are much larger than terrestrial moons and have higher gravity.

Gas giant moons also have different features than terrestrial moons. They are often composed of ice and rock, and some have active volcanoes, geysers, and subsurface oceans. Terrestrial moons, on the other hand, are typically dry and featureless.
