Jupiter's Cloud Decks

There are three different layer of clouds, or clouddecks, in Jupiter's atmosphere, as shown in this picture. The clouddecks are made of different molecules.

The first clouddeck is made of ammonia clouds. Ammonia is what you use to clean the kitchen sink, so you can imagine what clouds of ammonia might smell like!

The second clouddeck is made of ammonium hydrosulfide clouds, which is a combination of ammonia and sulfur! You can imagine what *that* smells like.

The third clouddeck is made of ordinary water clouds.

Jupiter's Troposphere

The troposphere of Jupiter is where the clouds are. Clouds form in regions of strong atmospheric motion, when condensation takes place. The troposphere is the region rapidly stirred by vertical motions....more
