Ecosystems in Space Lecture Activity

  • The Earth's axis is currently tilted by 23.5 degrees

  • The Earth's tilt arose during the formation of the solar system, and oscillates between 21 and 25 degrees from perpendicular about every 100,000 years.

  • What do you think would happen to the climate and vegetation of Champaign-Urbana if the axis of the earth was tilted at a greater angle, perhaps 45 degrees?

  • *Hint: Champaign-Urbana is located at about 40 degrees North Latitude*

    1. Get together with 1 or 2 people near you to discuss your answer.

    2. Each person should write the answer on a separate piece of paper.
