Both jupiter and saturn radiate more heat into space than they receive from the sun. What is the primary source of heat in the giant planets?.

Both Jupiter and Saturn radiate more heat into the space then the receive from the sun the primary source of the heat in the giant planets is the the settlement of the gases in the core of these planets.Many billion years ago when Jupiter was in the initial stage of its formation.The small planetesimals and the high pressure gas gather together because of the gravitational pull.When the gas and the planetesimals combined with each other they lost their gravitational energy.This gravitational energy don't into heat.This type of heat is called primordial heat.Now about Saturn, one of the inner core of the Saturn is still differentiating. It means that the formation of Helium and hydrogen is continuously taking place even now in the mantle of Saturn.When the helium gas false and settled down it releases gravitational energy which heat ups the inner part of the saturn.These are the primary source of heat energy for these planets.To know more about planets, visit,https://brainly.com/question/600212#SPJ4
