What are some resources for educators who want to teach about Earth's axial tilt and seasons?

Mar 24, 2000 ... Today, the Earth's axis is tilted 23.5 degrees from the plane of its orbit around the sun. But this tilt changes. During a cycle that averages ... Jun 15, 2016 ... Here we will discuss how the motion of the Earth's axis has altered, in four thousand years, this alignment of half a degree. The Earth's axis is an imaginary straight line around which the Earth spins once per day. The two locations where the axis and the Earth's surface intersect Nov 25, 2024 ...
