Some Jovian moons may have liquid water

Question

Quizplus · Accepted Answer

Jovian moons are moons that orbit the gas giant planets, including Jupiter, Saturn, Uranus, and Neptune. Some of these moons, such as Europa and Ganymede, are believed to have subsurface oceans of liquid water. This is because these moons have icy exteriors, but their interiors are heated by tidal forces caused by the strong gravitational pull of their host planet. As a result, the internal temperatures of these moons may be high enough to keep water in a liquid state. Therefore, the best choice is A, which states that liquid water may be present beneath the surfaces of Jovian moons. Choices B, C, and D are not accurate because there is no evidence to suggest that Jovian moons have liquid water at their centers, on their surfaces, or in their atmospheres, respectively.
