The moon is moving further from the Earth. To the extent that after 600 million years we will no longer enjoy full solar eclipses as it will be too far away to completely block the sun.

The reason the moon is moving away is because the Earth's rotation of 1 day is faster than the moon's orbit of about 28 days. The Earth's rotation is slowing as it transfers energy to elevate the moon. A by product of the Earth's tides where the moon drags the water.

Note that while conceptually the Earth is accelerating the moon, this acceleration boosts the moon to a higher orbit and its effectively moving slower as a result of this "acceleration"

I'm pretty sure that if the Earth were solid with no flowing liquids this "tidal leash" would have no effect. Maybe a tiny effect as mountains would be gravitational features.

So that's my question: Am I right that the moon's altitude increase would cease if the Earth didn't have liquid oceans?
