Regents Earth Science Unit 7: Water Cycle and Climate Name Section Coastal and Continental Temperature Ranges Lab # Introduction: There are large variations in average monthly temperatures among cities located at the same latitude. This suggests that factors besides the angle and duration of insolation (INcoming SOLAr radiation) affect the rate of heating and cooling of any given location. Objective: You will graph the average monthly temperatures of coastal and inland continental regions and interpret the range in temperatures. Procedure: 1. Graph the average monthly temperatures for the four cities given on the data table. 2. Plot all four curves on the same set of axes. 3. Use a different color for each city and include a key.

Average Monthly Temperatures Discussion Questions: 1. Even if you didn t know these were all cities of the United States, how could you tell from the temperature curves that they were all in the northern hemisphere? Coastal Continent Lab 2 3/18/2011
2. Which city has the greatest yearly temperature range? 3. Explain the cause of the greater range for that city. 4. How do the rates of heating and cooling differ for New York and Bismarck? 5. What is the yearly temperature range for Los Angeles? And for Phoenix? 6. Since Los Angeles and Phoenix are at the same latitude, the intensity of insolation (amount of heat from the sun) at both locations is the SAME... if that s true, then explain the difference in the temperature curves for the two cities. 7. Describe the difference in the annual temperature range between a coastal region and an inland region. 8. Which one of the following statements best explains why climates at continental shorelines generally have a smaller yearly temperature range than inland climates at the same latitude? A) Land changes temperature rapidly, due to the high specific heat and lack of transparency of land. B) Ocean water changes temperature slowly, due to the high specific heat and transparency of water. C) Ocean water is a good absorber and a good conductor of heat energy. D) Land is a poor absorber and a poor conductor of heat energy. Coastal Continent Lab 3 3/18/2011
9. Compared to an inland location of the same elevation and latitude, a coastal location is likely to have A) warmer summers and cooler winters B) cooler summers and warmer winters C) warmer summers and warmer winters D) cooler summers and cooler winters The map below shows an imaginary continent on Earth. Arrows represent prevailing wind directions. Letters A through D represent locations on the continent. Locations A and B are at the same latitude and at the same elevation at the base of the mountains. 10. Over the course of a year, compared to location B, location A will have A) less precipitation and a greater temperature range B) less precipitation and a smaller temperature range C) more precipitation and a smaller temperature range D) more precipitation and a greater temperature range 11. The climate at location C is much drier than at location D. This difference is best explained by the fact that location C is located A) at a latitude that experiences longer average annual daylight B) at a latitude where air is sinking and surface winds diverge C) farther from any mountain range D) closer to a large body of water Coastal Continent Lab 4 3/18/2011
12. According to the Earth Science Reference Tables, the climate of which location in New York State is influenced least by large bodies of water? A) Buffalo B) Jamestown C) New York City D) Binghamton 13. A city located near the center of a large continent has colder winters and warmer summers than a city at the same elevation and latitude located on the continent's coast. Which statement best explains the difference between the cities' climates? A) Air masses originate only over land. B) Wind speeds are greater over land than over oceans. C) Water changes temperature more rapidly than land. D) Land has a lower specific heat than water. 14. The diagram below represents a landscape profile. Points A, B, C, D, and E are locations in the mid-latitudes of the Northern Hemisphere. 15. At which location would the daily temperature range during the month of July be smallest? A) B B) E C) C D) D Coastal Continent Lab 5 3/18/2011
