Rotation and Revolution of Earth. Scroll over each position of the Earth below.

Now Let’s Analyze the Diagram:

• This diagram shows the rotation and revolution, which happen at the same time
• Notice the angle of Earth’s tilt does not change as it revolves around the sun
• Notice the purple circular arrows at the top of each Earth’s Rotation
• Earth rotates every 24 hours (1 day) and revolves every 365 days (one year)
• The Northern Hemisphere is tilted at the most extreme toward the sun during summer
• The extreme tilt toward the sun means the Northern Hemisphere is getting the most light (so more daylight) and the most heat (so warmer temperatures) than any other time of year
• The Northern Hemisphere is tilted at the most extreme away from the sun during winter
• The extreme tilt away from the sun means the Northern Hemisphere is getting the least light (so less daylight) and the least heat (so colder temperatures) than any other time of year
