Earth’s surface is a patchwork of climates, but the pattern is not random. There is an order to climate zones: students just need a key to unlock this climate puzzle.

Climate is not the same as weather. Weather is the day to day, even hour to hour condition of Earth’s lower atmosphere, but climate is the long-term average of atmospheric conditions at a particular place on Earth’s surface.

Certain factors interact to determine the climate of a particular place: latitude, elevation, prevailing winds, ocean currents, landforms, and location relative to water.

Constructing a Climate Graph

a) Make copies of the climate graph template for each student. Have students examine the template, observing that the left axis shows precipitation in millimeters; the right axis shows temperature in degrees Celsius; and the base identifies a column for each month of the year.

b) Look at the sample climate graph shown above. Point out that precipitation is represented by bars, while temperature is represented by points connected by a line. The color used relates to the climate zone in which the location is found. Access a map of climate zones with a color key at http://www.srh.noaa.gov/jetstream/global/climate_max.htm .

c) Precipitation and temperature data for thousands of locations worldwide can be found at http://www.worldclimate.com/ . Assign each student a different state in the US. Have students identify the largest city in that state. Then have them use the World Climate web site to find data for that city in order to plot precipitation bars and temperature points to create a climate graph. Remind students to use the correct color on their graphs (see the climate zone map referenced in step b, above). Also ask them to label the climate station, absolute location, and elevation of their assigned city.

Thinking Critically

a) When students have completed their climate graphs, have them locate each station on a map of the USA.

b) What climate characteristics does each location have? How are the locations similar? …different?

c) How do factors such as latitude, elevation, prevailing winds, ocean currents, landforms, and location relative to water help explain these similarities or differences?

Extending the Activity

a) Repeat the activity using cities from major world regions. Use a search engine to find images that are representative of each climate type.

### Share

Each year thousands of schools in the United States participate in the National Geographic Bee using materials prepared by the National Geographic Society. The contest is designed to inspire students to be curious about the world. Schools with students in grades four through eight are eligible for this entertaining and challenging competition.

Registration for the 2015 Geo Bee has ended. Schools can register for next year's Geo Bee in August 2015.

School Geo Bees have all been held. Please mark your calendar for the upcoming State Geo Bee on March 27, 2015, in all 50 states and the District of Columbia. To find out the location of the State Geo Bee for your state, email us at ngbee@ngs.org.

The national competition of the Geo Bee will be held May 11-13, 2015, at the National Geographic Society’s headquarters in Washington, D.C. It will be televised on May 15, 2015, at 8 p.m. on the National Geographic Channel and NG Wild.

### Gain a Global Perspective
