This is the boat that my family has at Grand Lake in Oklahoma. Some people mistakenly believe the reason for Earth's hot and cold seasons is because the orbit takes Earth closer to and farther from the Sun. The reason for seasons is rotation, revolution, and most importantly, tilt or incliniation of Earth on its axis. The image to the left is one I created with SmartDraw , showing inclination of the Earth to the Sun at the different seasons. In the summer, the scenario is reversed, that is, Earth's northern hemisphere receives direct sun and the southern hemisphere, less direct.
More direct rays result in longer days and more heat.
During summer and winter, the Arctic and Antarctic Circles will have times in which there is 24 hours of sunlight or darkness. Return to the Student's Webpages .
