1. When is Denver, CO closest to the sun? What season is it?

2. When is Melbourne, Australia closest to the sun? What season is it?

3. Can the distance from the Earth to the Sun account for the seasons? Explain your reasonings using what we have learned in this lab.

Since the Earth is tilted (at 23.5 degrees), there is always a part of the Earth that is slightly closer to the sun. For instance, in June, the northern hemisphere is closer to the sun than the southern hemisphere by a few thousand kilometers if someone is looking at two cities that are at equal latitudes in each hemisphere (for example, Denver and Melbourne).

The average distance from the Sun to the Earth is 1 AU = 149, 598, 000 km. The extra distance that the sunlight must travel is on the order of 10,000 km (or less). What percentage of the Earth's total distance from the Sun is this extra distance? ((Extra distance in km)/(Earth's average distance from the sun in km))x100 = ____________ %

Dose the distance that the sun's light must travel is the cause of the varying temperatures of the seasons?
