How does that even make remote sense? Take water, make a stream going down hill, put water in it. There, a river going the opposite direction of Earths rotation.

How is that water able to overcome the directional force of a 1000mph rotation?

Because it's going downhill...

It's the same thing as throwing a ball in a moving train. The water accelerated to the speed of the Earth's rotation, and that allowed it to act as though it were in a resting state, when in fact it was matching the speed of Earth's rotation. In fact, the Earth's rotation DOES affect it some, due to the Coriolis Effect. The Coriolis Effect states that rivers in Northern Hemisphere will curve to the right and rivers in the Southern Hemisphere will curve to the left. If you stand on the Northern Hemisphere and face the equator, then you will see that the river curves in the opposite direction of Earth [b][u]rotation[/u][/b], and the same thing happens for the Southern Hemisphere.

I'm a 13 year old with a basic understanding of modern physics, relativity and quantum mechanics.[/spoiler] Edit: Had to make this post short on time, counter me on any holes I left in this post and I will be happy to fill them in.

Your explanation fails to address the fact the earth's supposed 1000mph rotation would eject said rivers into space. Ignoring this, your explanation is still flawed as throwing a ball on a buds has NO relation to massive bodies of water on the earth's surface.

Edited by Rick Sanchez: 2/21/2017 8:14:33 AMDo you KNOW the speed required to escape earths gravitational force? The escape velocity is around 25,000 mp/h. That is 2.5 times the rotation speed of the earth. This being said. If you up the earth's rotation speed by 250%, then you might be able to lift off just by the rotation. Earth's rotation: 1180.47 m/s Escape Velocity: 11180 m/s 11180 > 1180.47 TL;DR the speed the Earth rotates is 250% less than the speed needed to escape earth's gravity.

Ok fine. But you are still digging your own grave. Earth supposedly moves through space at 67,000mph. How is it that bodies of water opposite this directional do not get "sucked" off, like someone letting go of the exterior of a moving plane?

I'm not entirely sure on that subject, but here is my hypothesis: the pressure of the atmosphere help by "weighing" the oceans down, and there is nothing to pull the oceans off the earth and into space. The pressure of the atmosphere at sea level is 101 kPa (kilopascals) of pressure. If you wired a straw from 0 meters to space, the ocean water would only rise around 16-20 feet. The pressure from the atmosphere isn't enough to counter the force of gravity and to lift something as heavy as water. And the plane example you gave is flawed; there is wind resistance on the plane. That is why your decelerate if you let go of something like that (and gravity too). In space there is no resistance to strip any material off of the earth's surface.

I've never been so proud of a 13 year old.

Agreed.

Because, as it happens, the force of gravity (calculated thus:) F[g] = Gm[1]m[2] / r*r is greater than the centripedal force: F = mv*v / r meaning that the water remains on the earth's surface.
