Latitude lines go from 0 degrees to 90 degrees both north and south. Latitude shows how far you are from the equator. Climates are colder as you move away from the equator. Latitude lines split the globe into six major climate regions. These climate zones are on your climate zone graphic organizer in your notes. Be sure to know all the information on the outside and inside of this graphic orgainzer!

Direct and Indirect light: The reason that latitude affects temperature is that it shows what areas of the Earth receive direct light and which receive indirect light.

Tropics: this area is the warmest because at some point inthe tropics the sun's light is hitting the earth at a 90 degree angle. This is direct light and it is intense (very warm!).

Temperate: In these regions the sun's light hits at an angle less than 90 degrees and more than 45 degrees. The light is indirect, but still intense enough to be hot in summer. These areas have 4 seasons.

Polar: these areas recieve very indirect light at an angle less than 45 degrees. This makes these regions very cold all year. Because of the extreme cold they actually receive very little precipitation.
