Question

which of the following does saturn have in common with earth? its well - defined shape its gassy composition its single moon its solid core

Explanation:

Earth is a terrestrial planet with a solid core, and Saturn (a gas giant) is also believed to have a solid core. Earth has a well-defined shape (spherical), but Saturn is oblate due to rotation—this is not a common "well-defined shape" in the same sense. Earth has a rocky composition, not gassy. Earth has one moon, while Saturn has over 100 moons.

Answer:

its solid core
