"Is the earth's rotation slowing down?
Asked by: Mallory Thomson

Answer
Yes it is, due to a transfer of Earth's rotational momentum to the Moon's orbital momentum as tidal friction slows the Earth's rotation. That increase in the Moon's speed is causing it to slowly recede from Earth (about 4 cm per year), increasing its orbital period and the length of a month as well.

To picture what is happening, imagine yourself riding a bicycle on a track built around a Merry-go-Round. You are riding in the same direction that it is turning. If you have a lasso and rope one of the horses, you would gain speed and the Merry-Go-Round would lose some. In this analogy, you and your bike represent the Moon, the Merry-Go-Round is the rotating Earth, and your lasso is gravity. In orbital mechanics, a gain in speed results in a higher orbit.

The slowing rotation of the Earth results in a longer day as well as a longer month. Once the length of a day equals the length of a month, the tidal friction mechanism will cease. (ie. Once your speed on the track matches the speed of the horses, you can't gain any more speed with your lasso trick.) That's been projected to happen once the day and month both equal about 47 (current) days, billions of years in the future. If the Earth and Moon still exist, the Moon's distance will have increased to about 135% of its current value.

Oooh. The MOON.Jovial Monk wrote on Jul 21^st, 2017 at 4:51pm:


The same person who does not do any research because he "knows" the answers, you.

Remember what I said about the noise. Like Satellite altimetry - accuracy to about 34mm, but can measure sea level rise to about 4mm.

The moon has been moving away from us for a long time.

Poor desperate Lees.

The Internet doesn't forget: the fake conservatives can't believe they put crapper net around their kids kids kids necks in the once allegedly proud country that built the Asian century!

Turnbull is public enemy number one and the interloper is even worse for the memory.... Then the memories stream back to the Costello grin or the Howard mealy mouthed stench!



.... A river either grows or it stagnates and dies and the smell of death surrounds the average liberal voting household dealing with hungover crack smoking tryhard kids from the paper profiteering era!

Trends are trends

Not anywhere near rapidly enough to upset the AGW theory.

All things still being equal.

See SN’s post on corrected sea level rise? Interesting, not?

I bet you about pood yourself reading it. 

I'm still wondering who "SN" is ?
