Final answer:
The properties of the volcanoes on Io can be compared to those of terrestrial volcanoes. Two similarities and two differences are outlined.
Step-by-step explanation:
The properties of the volcanoes on Io, one of Jupiter's moons, can be compared to those of terrestrial volcanoes. Two similarities between the two are:
- Both Io's volcanoes and terrestrial volcanoes are driven by eruptions of molten silicates.
- Both Io's volcanoes and terrestrial volcanoes have the ability to produce lava flows.
Two differences between Io's volcanoes and terrestrial volcanoes are:
- Io's volcanoes can produce eruptive plumes made of sulfur and sulfur dioxide, resulting in colorful "snowfalls" on the moon's surface, whereas terrestrial volcanoes do not produce such plumes.
- Io's volcanoes can have major new surface features appear between orbits, while terrestrial volcanoes do not exhibit such behavior.
