Question 27

Earth's rotation appears to be slowing approximately 2 seconds every 100,000 years. Why are Earth's days getting longer?
  1. Too much tilt on its axis.
  2. Earth's revolution around our Sun is changing drastically.
  3. Tidal cycles create a “drag” on Earth, causing it to slow down.
  4. Earth’s axis is becoming perpendicular to the incoming rays of the Sun.
