The earth rotates! Isn't it? A chopper that goes up and hovers lands on the same spot. It doesn't add up Why?

Since the helicopter started from the ground, it is also in good agreement that when it hovers it gains the momentum of the earth's rotation.

No, and the Earth won't rotate 'backwards', but if it did, it would be a global disaster. The spin of the earth slightly counteracts gravity, so if the earth stopped and turned around, the tsunamis, earthquakes, and global havoc would be immense.

Have you ever seen trees still, then suddenly start shaking around or "swaying" inexplicably--with no one else around? Have you ever been in or seen a sailboat?  The motion of acceleration that did not come from an engine is to be explained how?  Have you ever driven with your windows open?  Storms do not just stay in one place, rather they proceed across the continent.  All of these things are attributable to....WIND! I win lol!  P.S. Just because you haven't seen something--doesn't mean it doesn't exist: ex= a baby pigeon!  lol

Not clear what you mean?  How does it stay up in space? It does that because it is going very fast, which would take it away from earth, but gravity is pulling it back, causing it to curve, and go around the earth, just like a string on a yo-yo if you just whip it around your head. \n\nIf you mean, what does it do, there are different kinds, but most of them get power from solar panels, and have radio receivers and transmitters to communicate back to earth.

The geological makeup of the Earth to begin with! It isnt a perfectly balanced orb. Secondly, the orbit of the moon and any other objects in the solar system with enough mass. Get your toy top out. A top is  not a perfectly balanced object. It would be impossible to attain this. Spin the top and watch its balance decay. Same principle.

are you retarded? the earth is a miniscule speck in the universe, and the sky happens to be part of that universe..... really, this isn't even worthy enough to answer.

That's because the Earth's spin is caused by electromagnetics.  Something about the electrical properties of these gasses in our atmosphere causes them to be spun around faster than the rest of the Earth.

Yes, the moon spins (or rotates) once for each revolution (orbit).  This happens because the moon is "tidally locked" to the earth.  \n\nThe moon exerts tidal forces on the earth because it pulls harder on the part of the earth closer to the moon and less hard on the part of the earth father from the moon.  The result is tides--the ocean bulges up on the side close to the moon because of the harder pull and actually bulges up away from the moon on the far side because of the weaker pull.\n\nThe earth also exerts tidal fores on the moon.  The moon has no oceans (and never did), but the solid rock of the moon bulged.  The moon used to spin much faster, but bulging and rotating causes friction, which slowed the moon's rotation until it keeps one face toward the earth.  Thus, the bulge is fixed in one place on the moon and no more friction!

the earth spins in the same direction for everybody....it rises in the east and sets in the west

The laws of physics say that an object in motoin will remain in motion unless acted upon by an outside force.  It's hard to conceive of anything that would make Earth's core stop spinning short of some planet destroying catastrophe.

The atmosphere rotates with the earth (for the most part), so that things in the atmosphere are carried around with the earth.  Also, the baloon had momentum carrying it in the direction of the earths rotation and it does'nt fly off on a tangent due to gravity.

The satellite has a straight rotation around the earth but most do not have the same direction of rotation as the earth. but a tilted rotation so that it passes from the northern hemesphere to the southeren hemesphere. combined with the earths actual rotation makes it look like the satellite zig zag

Because the plane moves along with the earth because of inertia, even after it leaves the ground. If it didn't, then when you jumped straight up, you would land about a hundred meters from where you started.

If you're at ground-level, then it could be any car, bicycle, skateboard, or scooter.  Even a skier moves parallel to the Earth's surface.  (The Earth's surface happens to be very inclined on a mountain.)  \n\nFarther away from the Earth, it's a circular orbit around the Earth.

It doesn't wobble exactly, though if appears that way from Earth. The main cause of this libration, as the wobble is called, is that the moon's orbit is slightly elliptical. This makes it move faster in its obit at some times (when it's closer to Earth). Its axial rotation, however, is at a constant speed, so the axial rotation and orbital revolution don't quite perfectly synchronize. So when the moon is moving fast, we see a little more of the trailing edge, and when its slow, a little more of the leading edge. \n\nSome of the wobble is also due to the tilt of the moon's axis and the inclination of its orbit relative to ours.

Have you ever noticed that the sun appears to come up on one side of the horizon, and then several hours later it seems to sink down on the other side of the horizon?\n\nIf you ever noticed this phenomenon, you were aware of the Earth spinning.

The earth isn't round. It's a squashed sphere, due to it's rotation.\n\nI wish grass fell from the sky. I have to go find a guy who knows a guy to get my grass.
