Two students designed an experiment to study the effect of solar radiations on four cities of Earth. They used a globe to represent Earth and a flashlight to represent the sun. The four cities were labeled A, B, C, and D on the globe at the latitudes shown in the chart below. City Latitude A 39° 56' N B 60° 08' N C 25° 48'N D 42° 21'N One of the students used the flashlight to light Earth while the other student rotated the globe slowly. Based on the experiment, the students are most likely to conclude that maximum hours of sunlight will be received on the first day of summer in the northern hemisphere at City A City B City C City D

|dw:1338414269021:dw| You have to pick the city closest to when the sun is overhead. That means you must know how to plot a city on the circle. A city at latitude 0º would be at the equator. 45º is halfway between the equator and the north pole. Can you pick the city closest to the sun?
