FACTORS THAT INFLUENCE CLIMATE

You are a meteorologist who is studying climate in cities around the world.

You are studying average temperatures, and are finding some interesting trends in the data!

Analyze the evidence, and prepare to discover what influences climate around the world.

I. CONSIDER THE SCIENTIFIC QUESTION

What factors influence average temperatures around the world? Based on your conclusion, what information do you need to predict average temperature in any city for a certain month?

II. GATHER EVIDENCE

1. Analyze the world map at http://www.earthkam.ucsd.edu/public/educators/pdf/GeoImportandFactsLatAndLong.pdf to review longitude and latitude.

2. Read the definition of elevation.

3. Print data collecton sheet.

4. Visit http://www.weatherbase.com. Find a city in the United States that is near you (click on United States, your state, and a city near you). On your data collection sheet, record:

Latitude

Longitude

Elevation

Average Temperature for March

Repeat this for a city in:

Africa

Antarctica

Asia

Australia

Caribbean

Central America

Europe

Middle East

South America

III. DRAW CONCLUSIONS

1. Based on your data, what can you conclude about how latitude, longitude, and elevation affect temperature? Complete the “Observations of Average Temperatures" portion of your "Factors that Influence Climate" Analysis .

2. After making your prediction about what factors influence temperature, visit the following Web sites, and then complete the “Research on Climate ” portion of your worksheet.

IV. CONSIDER ALTERNATIVES

Are there any temperatures that can’t be supported by your hypothesis? What could be explanations for the cause of these variations? Visit the following Web site to explore possibilities, and then complete the "Alternative Explanations for Climate" portion of your worksheet.
