a solid "rock" would seem to keep spinning "balanced" but if it rotated (with its gravitational "pull" of its orbiting moons' gravitational "pull") with an orbiting moon reacting like it does with Earths tides it seems friction should have a much bigger effect on either the moons' orbiting distance from Earth and/or the rate of rotation of the Earth.

it does! from some billions of years now, the day will be twice as long. its because gravity kinda holds the body of water quite loosely than solid stuff ( also goes for gasses ). so the water kinda gets dragged along which also kinda pushes the direction opposite of the earth's rotation. so there's friction right. every two things that have friction between will eventually stop, even though some would take lots and lots of time

Tides are because of the rotation of earth faraway from the moon, so for this reason the tides flow besides beacuse of the moon's pull. So vegetation have not something to do with that because of the fact so a tactics as i'm conscious the moon has no "pull" on them although the solar does, like how sunflowers turn in the direction of the solar... besides, the rotation of the earth reasons the tides, and whilst each action has an equivalent and opposite reaction the tides do not impact the rotation... buttt i'm not a scientist...

"His was the first mathematical analysis of the evolution of Earth's Moon. He suggested that since the effect of the tides has been to slow the Earth's rotation and to cause the Moon to recede from the Earth, then by extrapolating back 4.5 billion years ago the Moon and the Earth would have been very close, with a day being less than five hours. Before this time the two bodies would actually have been one, until the Moon was torn away from the Earth by powerful solar tides that would have deformed the Earth every 2.5 hours."

It does, and tidal, and wind power will slow it even faster, which is undesirable! The Earth used to rotate 4.6 billion years ago, 3 times faster than it does, at present. eSsLaEe is incorrect: the proto-Earth was impacted by a Mars sized body: the 2 nickel-iron cores fused, and the detritus formed a ring, eventually accreting to form the moon. This is known by the fact the the Earth is the densest planet in the solar system, and has a strong magnetic field. The moon is considerably less dense, with a very weak magnetic field, even taking account its much smalled size, owing to the loss of that nickel-iron core.

Friction from Earth's ocean tides *is* slowing the planet's rotation, by some 2.2 seconds per 100,000 years. For this reason what are called 'leap seconds' are periodically added to our time keeping as compensation.

" Friction between the oceans and the Earth's surface is slowing the Earth's rotation by 0.002 seconds every 100 years. "
Yeah, "Kid's Space"!

It does. It's just such a small effect that it takes millions of years to have an effect.

Gravity holds the water on Earth and it is rotating at the same speed that the rest of the Earth is...what's to slow down?

very intresting question, and yes i can only assume with friction the the world may stop moving, maybe sometime tomorow??

Maybe I'm a bit dim, but I can't see where any friction would come from.
