question 56

Multiple Choice

• B) Io is tidally heated by tidal forces exerted by the outer Galilean moons, which flex and distort its interior
• C) Io has much more radioactive decay occurring inside it than does the Earth
• D) Io is tidally heated due to its elliptical orbit, which causes the large tidal forces exerted by Jupiter to constantly change, flexing and distorting its interior
