Nothing need keep anything spinning. A body in motion remains in motion ....

If they were initially in motion some force would have need to stop them from spinning. Got one in mind?

yes, if all the activity on earth didn't also obey the rotational forces of gravity then they might have slowed it down. A volcano can produce some little power, but if every leaf or apple that fell resisted the orbital force then why not.

Are you seriously proposing that somehow a leaves falling from trees might have stopped the earth from spinning?

ROFL ROFL ROFL

Please tell me I misunderstood.

Use your imagination. Four billion years of falls of everything, twice a day oceans, iceblocks, rocks, the volcanity activity that takes place inside the earth and plates moving. If they didn't also contribute to spin of the earth it might have slowed it down. A rock falls, it either contributes to the spin or gets dragged along. If it gets dragged along it slows the rotation. To contribute fully it must have a momentum of it's own. All objects on earth would orbit the centre of the earth if the path was clear to do so, it seems to me that they must therefore contribute to the spin.

Dogrock ... there are disciplines usually referred to as math and physics. You might want to study them at a level at least equal to that taught in middle school.

Your statement: "A rock falls, it either contributes to the spin or gets dragged along." is laughable.

And on your way to enlightenment you might want to watch an ice skater during the Winter Olympics.
