Extreme Elementals

You're somehow trapped inside a box where you can't see outside. When you listen to sounds, concentrate on smells what can you figure out about where you are and what is outside each wall of the box? Each of the four sides opens to a different element, all of them pretty extreme conditions: ice and instant freezing, fire and lava, bottomless pit of water and open air - the only safe side.

You'll need to figure it out quick. What you don't know is that the box you are in will be shipped off to an alien planet if you can't escape before the aliens launch their spaceship.
