When you lift by convection, you move thermal energy upwards.

<span>Terrestrial planets were formed in a territory where it was too hot for ice and gas to condense but the Jovian planets formed in colder locations. The terrestrial planets also are too small in size to apply the gravitational pull which is required to hold very light gases in their atmospheres.</span>
