Hemisphere without showing the Coriolis effect. Which dashed arrow represents how the wind direction will change

in the Northern Hemisphere due to the Coriolis effect?

30 The map below shows a portion of the Middle East. Points A, B, C, D, and X are locations on Earth’s

surface.

A Lake-Effect Snowstorm

A snowstorm affected western New York State on October 12 and 13, 2006. A blend of weather conditions caused

more than 24 inches of heavy, wet, lake-effect snow, bringing much of western New York to a standstill. The New

York State Thruway was closed to traffic between exits 46 and 59, which are circled on the map. The

isolines on the map show the amount of snowfall, measured in inches, resulting from this storm. Points A and B

represent locations on Earth’s surface.

69 On the grid below, construct a profile of the snowfall amounts along line AB by plotting

the isoline amounts that cross line AB. The amounts for points A and B have been plotted. Complete the

profile by connecting all the plots with a line. [1]

71 Determine the number of inches of snow that was received in Niagara Falls, New York, from this

snowstorm. [1]

shown on the map. [1]
