Because terrestrial planets - those made of rocks - could never become so large. The gravitation pressure on a "massive" rock planet would be so great that it would rupture and break apart.
Gas does not have this problem, so they can grow to much larger sizes.
Also, the is more "gas" than "rock" in the Universe, so there are more building material for large gas giants.
What else can I help you with?
Do the gas giants have thinner atmosphere than the terrestrial planets?
No. As the name gas giant implies, these planets are made largely of gas. They have extremely thick atmospheres.
Are otter planets made out of gas?
i think the question is " are other planets made out of gas" because as far as i know there are no otter planets, although that would be cool. not all planets are made out of gas, some are gas though. neptune is a gas giant, that's just one example though
Is Neptune a rocky or a gas giant?

Why is jupiter called a gas giant?
