Altitude
From Wikipedia, a free encyclopedia written in simple English for easy reading.
Altitude is normally defined as the height of an object or place above sea level. For every 1000 metres you go higher, the temperature drops three degrees. A good example of air rising and cooling to become snow is Mount Cotopaxi in Ecuador. Ecuador virtually runs through the equator however Cotopaxi manages to get snow on its peak due to air rising, creating water vapor and then cooling to become snow.
