There are 10 types of clouds that can be seen from most parts of the world.
They can either be low, middle or high clouds and brings different types of precipitation.

For this cache, the focus is on CUMULUS CLOUDS.
Often called "fair-weathered" clouds, cumulus clouds are common over land on sunny days, when the sun heats the land creating thermal convestion currents.
Each thermal is distinct, and, consequently, each cumulus cloud is a distinct puff.
There are three species of cumulus clouds:
- humilis are wider than they are tall
- mediocris are as wide as they are tall
- congestus are taller than they are wide
There typical altitude is between 2000 and 3000ft. They can be seen worldwide, except in Antartica, where it is to cold. They generally do not bring any precipitation, except for brief showers from congestus. They are made up of liquid water and forms due to thermal convection currents.
