1. WEATHER

2. WEATHER vs CLIMATE
Definition: the condition of the atmosphere at a certain location and time “What you get”
Definition: conditions of atmosphere at a certain location over a long period of time “What you expect”

3. WEATHER vs. CLIMATE “Look out the window”
“What is the weather usually like in winter?”

4. Pull out the Landforms Region map from last class period

5. Factors that Influence Weather
1. Amount of solar energy- air masses absorb energy 2. Water vapor- determines precipitation 3. Cloud cover- hold water vapor 4. Landforms/bodies of water 5. Elevation- higher air loses ability to hold moisture 6. Wind

6. WEATHER EXTREMES
1. Hurricane/typhoons: storms that form over warm, tropical ocean waters.

7. 2. Tornadoes: (twisters) powerful funnel-shaped columns of spiraling air.

8. CLIMATE

9. Factors that Influence Climate
1. Wind Currents: Wind is the flow of a huge amount of air, usually from a high pressure area to a low pressure area.
High= COLD Low= WARM

10. 2. Ocean Currents: rivers flowing in the ocean
If I live by the coast is it going to be a MODERATE or EXTREME climate?
-Warm water flows from equator to the north pole
-cold water comes from north pole to equator
In Northern Hemisphere

11. Ocean Currents

12. 3. Zones of Latitude: Where are you in the world and where is the sun??
COLD
HOT
WARM

13. 4. Elevation: distance above sea level
air temp. decreases as you go higher

14. Orographic Effect: mountains get in the way, warm air rises, making one side of the mountain green and the other dry.

16. Climate Change: True or False
TRUE. It’s a fact that climates change over time. Climate change is both naturally occurring and human caused.

17. The Facts On average, air temperatures are increasing
Since 1800’s the temp of earth has increased ONE degree Fahrenheit
Scientists believe an increase of is possible in this century (100 years)
Greenhouse effect

18. The Greenhouse Effect
Definition: gases in the atmosphere that trap heat, which causes higher temperatures on Earth
Gases caused by burning coal, oil, methane, etc.
