Tidal friction caused by Earth's stretching from the Moon's gravity is gradually slowing down the rotation of Earth.

Question

Quizplus · Accepted Answer

Tidal friction caused by the Moon's gravity is gradually slowing down the rotation of Earth, leading to longer days. The elongation of the Earth's axis caused by the Moon's gravity creates a torque on the Earth, which causes a transfer of energy from Earth's rotation to the Moon's orbital motion, resulting in an increase in the Moon's distance from Earth and a corresponding slowdown in Earth's rotation.
