Whether differential rotation is exhibited by Jupiter’s moons of rock and ice, such as Ganymede.

Answer to Problem 1CC
Solution:
Jupiter’s moon, such as Ganymede, does not exhibit differential rotation as it has a solid core while differential rotation can only occur in liquid planets and moons.
Explanation of Solution
Introduction:
Differential rotation can be defined as the rotation of different parts of a celestial body with different
Explanation:
Ganymede appears to be an ice-covered moon as well as the largest moon in our solar system. It has three layers: one with a metallic core; a spherical shell of rock; and the surface covered in ice. This moon does not display differential rotation as for differential rotation to occur, it has to be made up of liquid plasma, such as Jupiter itself. Ganymede has a solid core, so differential rotation cannot take place.
Conclusion:
Hence, Jupiter’s moons of rock and ice do no exhibit differential rotation. They rotate at the same speed due to their solid core.
