Let's talk about the weather!

Clouds form when damp air is cooled, usually by rising. This may happen in three ways: When a wind rises to cross hills or mountains; when a mass of air rises over, or is pushed up by another mass of denser air; when local heating of the ground causes convection currents.

Cirrus
detached clouds composed of microscopic ice crystals, which gleam white in the sun resembling hair or feathers.

Cumulus
detached heaped up, dense low clouds. The sunlit parts are
brilliant white, while the bass (oops) BASE is relatively dark
and flat.

(Cumulo)nimbus
heavy and dense clouds associated with storms and rain. They have flat bases and a fluffy outline, extending upwards to great altitudes

Troposphere
The earth's weather conditions are limited to this layer which is relatively thin, extending upwards to about 8km at the poles and 15km at the equator. It contains 85 percent of the total atmospheric mass and almost all the water vapour
