Chapter 11

On which summer day would you expect the greatest temperature range? Which would have the smallest range in temperature? Explain your choices. a. Cloudy skies during the day and clear skies at night. b. clear skies during the day and cloudy skies at night c. clear skies during the day and clear skies at night d. cloudy skies during the day and cloudy skies at night

**see page 379 C would have the greatest range in temperature D would have the smallest range in temperature Clouds reduce daily temperature ranges, reflect radiation during the day. At night the minimum temperature won't fall as low because the clouds retard heat loss. The opposite is true for a clear day/clear night.

The Sun shines continually at the North Pole for 6 months, from the spring equinox until the autumnal equinox, yet temperatures never get very warm. Explain why this is the case.

**see pages 365-366 Earth is in such a position in its orbit that the axis is tilted neither toward nor away from the Sun, causing 24 hour sunshine. The sun is so far away that not enough energy is produced to warm.

Refer to the graph in Figure 11.3 to answer the following questions about temperatures in New York City: a. What is the approximate average daily high temperature in January? In July? b. Approximately what are the highest and lowest temperatures ever recorded?

a. 39.2 January 82.4 July b. 107.6 highest -4 lowest

Determine which statements refer to weather and which refer to climate. (one statement includes aspects of both weather and climate). a. The baseball game was rained out today b. January is Omaha's coldest month c. North Africa is the desert d. The high this afternoon was 25°C. e. Last evening a tornado ripped through central Oklahoma f. I am moving to southern Arizona because it is warm and sunny. g. Thursday's low of -20° C is the coldest temperature ever recorded for that city. h. It is partly cloudy.

a. weather b. climate c. climate d. weather e. weather f.climate and weather g.climate and weather h. weather **LLane: see pg. 354 E: I think is the only one that is both. f: I think is climate (I was raised in Tucson, AZ) g: I think is weather, (not normal for that city) Weather refers to the state of the atmosphere at a given time & place. Climate is based on observations that have been accumulated over many years-the sum of all statistical weather info that helps describe a place or region.
