That's Correct!
It's Wrong!
Jupiter, Saturn, Uranus, and Neptune are gas giants characterized by their massive size and predominantly gaseous composition. These planets lack solid surfaces and are primarily composed of hydrogen and helium, with traces of other gases. Their immense gravitational pull compresses the gases into dense atmospheres surrounding small, rocky cores. Unlike terrestrial planets such as Mars and Venus, gas giants have extensive atmospheres and lack well-defined surfaces.
