2. Review Weather vs. Climate Climate is determined by:
Temperature and Precipitation

3. Factors Affecting Temperature

Seasonal Winds

4. Temperature Zones
Based on latitude Earth’s surface can be broken into three temperature zones
They are:
Tropical zone
Polar zone
Temperate zone

5. Tropical Zone Near the equator 23.5 N and 23.5  S
Receives direct sunlight year round
Warm climates

6. Polar Zones 66.5  to 90  N and 66.5  to 90  S
Suns rays strike at a lower angle.
Cold Climates

7. Temperate Zones In between the tropical and polar zones.
In the summer, rays strike more direct angle.
In the winter, rays strike at a less direct angle.
Warm or hot summers, cool or cold winters
