1. Warm Up Compare weather vs. climate.
List three factors that determine global climate.

2. 4.1 Climate

3. Weather – day to day conditions of the atmosphere.
Climate - What are long-term weather patterns.
(year-after-year patterns)
-average temperature
-precipitation
-relative humidity

4. What factors determine global climate?
Sunlight
Water
Wind
Ocean Currents
Latitude
Solar energy trapped in the biosphere
Mountains/Elevation

5. Earth has three main climate zones.
The three main zones are the polar, tropical, and temperate climates.
Polar zone: the far northern and southern regions of Earth
Tropical zone: surrounds the equator
Temperate zone: the wide area in between the polar and tropical zones

6. The angle of the Sun’s rays help determine an area’s climate.
