- Eratosthenes of Cyrene measured a solar shadow at about 7.2o from the perpendicular in a well at Alexandria, Egypt, but no solar shadow (0o from the perpendicular) in a well at Syene, Egypt, 490 miles to the south, at midday on the summer solstice. From these measurements, he was able to calculate: that the circumference of the Earth is about 73,500 miles that the circumference of the Earth is about 61,250 miles that the circumference of the Earth is about 49,000 miles that the circumference of the Earth is about 36,750 miles E. that the circumference of the Earth is about 24,500 milesIf it takes 8 minutes for light from the sun to reach earth ,it will take approximately 240.4 minutes for light to reach the planet:Name A student collects the following data about the Sun, stars, moon, and Earth, Sun Location Use the table to answer questions 13 through 15.

- Figure 1. Ultraviolet Radiation Index across the World. The colors on this map of the world represent Ultraviolet (UV) Index values on a particular day in September 2015. The UV Index is a standardized scale of UV radiation intensity running from 0 (least intense) to 18 (most intense). The y-axis values are degrees of latitude, which range from the equator (0°) to the poles (90° north and −90° south). The x-axis values are degrees of longitude, which range from the prime meridian (0°) to the antemeridian (180° east and −180° west). (Source: European Space Agency,http://www.temis.nl/uvradiati on/UVindex.html.) I. Examine Figure 1 above and answer Questions 1–6. 1. Describe the relationship between the UV Index (the colored bar in Figure 1) and latitude (y-axis). 2. How do you explain the relationship between the UV Index and latitude?
