Vocabulary Words: 1. Rotation- earth spins on its axis - completes in 24 hours ( day and night) 2. Revolution –Earth spins around the Sun. - completes in 365 days (year). 3. Precession – Earth’s axis spins/rotates. - completes in 26, 000 years. - changes our northern star. 4. Nutation- irregularity ( zig-zag) in Earth’s precession by ½ or 0. 5 degree. - influences seasons. 5. Earth’s 23. 5 degrees tilt on its axis is responsible for the seasons, not the distance from the Sun.
