Unformatted text preview: The angle between the incoming rays of light and the surface of the land. Factors that affect Seasons on Earth • The Earth is tilted at 23.5 degrees on its axis • The tilt always points to the North Star • The Earth revolves around the sun every 365 days • When the Northern Hemisphere tilts towards the sun, it is summer. When the Northern Hemisphere tilts away from the sun, it is winter. • The solar angle affect the amount of energy that is being received by different parts of the Earth. • The solar angle changes because of the tilt of the Earth and its revolution around the Sun. The more direct (greater) the angle the more energy the Earth receives. • Summer days are longer and more hours of sunshine transfer more energy to Earth. • The Earth makes a full rotation on its axis every 24 hours to create night and day....
