Latitude and distance from the sea also affect climate. The thin air in high mountain areas absorbs less of the sun's heat than the thicker air at sea level.
The daily change in temperature also increases with distance from the sea.
(30) Snow and rain are very important to climate. Snow reflects as much as eighty or ninety percent of the heat from the sun, and makes the weather even colder. But a large forest area can reflect as little as five percent of the sun's heat. This makes the weather warmer.
Of course, the general effects of climate do not explain everything about the weather. For example, (31) both the driest place in the world and the place with the most rainy days are located in Chile. Calama, in the Atacama Desert. has had no rain for over 400 years. But during the year 1916, it rained in Bahia, Felix, Chile for 348 days.
