Major moon (and Pluto) review

Which of the following are "Galilean" moons? (largest moons of Jupiter)

• Calisto

• Io

• Enceladus

• Titan

• Triton

What best describes why Io is so volcanically active?

• It's large size allowed it to have a hot molten core

• Gravitational interactions with Jupiter generate heat in its core

• It rotates so quickly that it generates heat

• Asteroid strikes keep its surface molten

What is true of Europa's liquid water ocean

• It doesn't have one

• It's much shallower than Earth's

• It's about the same size as Earth's

• It's much larger than Earth's

What is the likely cause of the crack's on Ganymede's surface?

• Lines of impact craters

• Lines of volcanoes over hotspots

• Contraction of the surface as it cooled

• Movements of tectonic plates

What is the likely cause of Calisto's low density?

• It has equal amounts of rock and water

• It is the smallest of the Galilean moons

• It has a large proportion of carbon

Why is Enceladus the most reflective object in the solar system?

• It's almost entirely covered by clean water ice

• It has a surface covered in reflective silicate crystals

• It's so close to Saturn and can reflect large amounts of light

• It's craters have a mirroring effect with amplify reflected light

What are Titan's lakes mostly made of?

• Liquid water

• Liquid ethane

• Liquid methane

• Liquid nitrogen

What unique geological features does Triton have?

• Rivers of hydrocarbons like methane

• Tectonic plate formed subduction zones

• cryovolcanoes made of volatiles like ammonia and methane

• Canyons that are actively spreading apart

What is the main reason that demoted Pluto from being a planet?

• It was too small

• It didn't clear its orbital path

• It didn't have enough moons

• It has too much ice

Which of the following are moons of Saturn?

• Enceladus

• Titan

• Triton

• Europa
