What changes the angle at which sunlight strikes the earth?
As the sun rises in the east and sets in the west, it follows a path that changes with the seasons. During winter the sun’s highest point in the sky is quite low. During the summer the sun gets much higher and provides more direct, concentrated heating. Prof. Jon Kahl During the summer, the arc of shadows on the globe can form an almost-straight line depending upon the latitude. The solar noon shadow in summer is at its shortest length when the Sun is at it highest point along the ecliptic. During the winter, shadows are much longer throughout the day and can form a wide arc, with the solar noon shadow longer than in summer. Longer shadows are the result of the hemisphere tilting away from the Sun, which causes the Sun to appear much lower in the sky. Example of how shadows will appear in February or October Shadows move clockwise in the Northern Hemisphere because Earth rotates counterclockwise on its axis relative to the North Pole. Shadows move counterclockwise in the Southern Hemis
