On which planet, except the Earth, is the greenhouse effect observed?
Saturn
Jupiter
Uranium
Venus
If a planet's atmosphere contains radiatively active gases, they will radiate energy in all directions. Part of this radiation is directed towards the surface, warming it. The greenhouse effect on Venus is particularly large because its dense atmosphere consists mainly of carbon dioxide.
