Why is Venus so hot?

Question asked by: knowitall

Venus is so hot because of a runaway greenhouse effect.

Essentially radiation is mainly visible light that falls on a surface. However some is longer - infrared. Some gases absorb this more than others. Examples are carbon dioxide.

The greenhouse effect makes a planet warmer than it would be otherwise due to this absorption of reflected energy in the atmosphere trapping it in the confines of the planet.

With the earth not much water and carbon dioxide is in the atmosphere, it is mainly locked up elsewhere within the earth.

However, on Venus there is much more carbon dioxide in the atmosphere than here, and this has meant that the heat got trapped and then more did, creating a vicious cycle... and the planet got warmer and warmer.
