Dear Janice - It turns out that the answer to your question is similar to that for the explanation of seasons. Because the Earth's rotation axis is tilted with respect to the orbital path around the Sun, the Sun's rays spend more time directed at one hemisphere depending on the season. You may remember that places like Alaska and Antarctica have long nights in the winter and long days in the summer. Because we are past the spring equinox there is more daylight the farther north that you are. So the answer is in the latitude and not the longitude. Good question. Steve
