7. Overview
weather: the day-to-day condition of the Earth’s atmosphere at a particular time and place

8. climate
climate: the average, year-after-year conditions of temperature and precipitation

9. climate The Effect of Latitude

10. climate
3 Climate Zones
Tropical zone: very warm zone, receiving mostly direct sunlight all year
Polar zone: cold zone that receives low angle rays
Temperate zone: between polar and tropics and ranges from hot to cold depending on changing angle of the sun

13. Heat transport
Unequal heating of Earth’s surface drive wind and ocean currents
Convection currents between the poles and equator cause the wind and ocean to move heat (example: upwelling)
Land masses can block wind currents

14. greenhouse effect
Greenhouse effect is when gases in the atmosphere trap heat energy
Maintains the Earth’s temperature
Humans have increased these gases
