what is earth's rotational direction?

Well it depends on your frame of reference... it spins from west to east so if you were looking down on the earth from above the north pole then it's anti-clockwise. If you look from south pole, it's clockwise.

None specifically. \n\nAll celestial bodies rotate.  The earth is no different.

First, the Earth's Equator is tilted at 23-odd degrees to the plane of its orbit; second, the Earth is slightly flattened at the poles; and third, the Earth is spinning.  These have no effect around the time of the equinoxes.  However, at the solstices, the gradient of the Sun's gravitational field across the Earth's diameter causes the daytime equatorial bulge to be attracted more strongly than the nighttime equatorial bulge, so there is a torque apparently trying to pull the spin axis more upright relative to the orbit.  But, like a spinning top, angular momentum means that the effect is to push it sideways instead.  The tilt stays at 23-odd degrees, but the axis "precesses" and describes a great cone in a period of about 26,000 years.

Four hours.  The earth rotates through a full 360 degree circle in 24 hours, this means it rotates at the rate of 15 degrees and hour (360 divided by 24).  So it will take 4 hours to rotate through 60 degrees.

The Earth rotates counter-clockwise when viewed from above the North Pole. \n\nThe rotation causes a centrifugal force, which causes the bulge of the equator, and a coriolis force, which is important in determining the flow of jet streams in the atmosphere and currents in the ocean.

The Earth is rotating at about 1040 mph (~1670 kph) at the equator. The speed decreases relative to your distance to the (axial) poles, where it is effectively 0. \n\nTo find out the rotational speed where you live, simply multiply the equatorial rotation speed above by the cosine of your latitude.

The mean radius is 6371.0 km.  The radius at any latitude is equal to that times the cosine of the latitude.  The Earth turns once on it's axis in 23 hr 56 min 4.0989 sec, or 23.93447 hrs.\n\nIt takes that long to travel 2(Pi)(6371)(cos(lat)).  Divide that distance by the time above and you're in the ball park (neglecting the difference in polar and equatorial radii).\n\nNote: The figure given for the Earth's rotation is correct according to Astrophysical Data: Planets and Stars.  The 24-hour day is measured from noon to noon - in relation to the Sun.  The Earth kind of rolls around its orbit, so after it has turned thru one rotation it has also moved along its orbit.  It has to turn for another 53.9 sec past the full rotation for the Sun to be back to due south again.

The Earth's axial tilt varies between 21.5° and 24.5° with a 41,000 year periodicity (currently decreasing: 24.049 in 3300 BC, 23.443 in 1973, 23.439 in 2000), while the direction of the tilt gradually undergoes precession, moving in a slow circle over a period of about 25,800 years. However, other factors may change the axial tilt of Earth.

The direction of rotation is the direction you look in when you see clockwise rotation. It's the same as the positive axis of rotation, sometimes called the spin axis. (It's also the direction a right-handed screw moves in when turned clockwise.) It may initially be hard to imagine rotation as having a direction like this, but consider the inconsistency that arises when you think of it as being in the tangential (rolling) direction as you do now. What distinguishes the motion of the bottom of the wheel from the top, front or back? These all point in different directions, and there is really no reason that one should be any more of an indicator than another. It's as if rolling it on the ground is somehow a higher "priority" than on the ceiling. These directions, and the direction the wheel rolls in, all actually indicate translational (nonrotary) motions that result from rotation, not rotation itself.

That depends on where on Earth you are standing. At the poles, the Earth hardly spins at all, but as you travel towards the equator, the rotational speed picks up. This makes sense -- as the circumference of a circle increases, a single point along it has to travel faster to complete a revolution in the same amount of time. \n\nThe rotational speed of the Earth at the equator is about 1,038 miles per hour. The atmosphere at the equator is also slightly thicker due to rotation, and you weigh slightly less. At mid-latitudes, the speed of the Earth's rotation decreases to 700 to 900 miles per hour. \n\nIf the Earth were to stop spinning suddenly, the atmosphere would still be zipping along nicely at around 1,000 miles an hour. As a result, everything not attached to bedrock would pretty much be scoured clean. \n\nThe circumference of the Earth at the equator is 25,000 miles. The Earth rotates in about 24 hours. Therefore, if you were to hang above the surface of the Earth at the equator without moving, you would see 25,000 miles pass by in 24 hours, at a speed of 25000/24 or just over 1000 miles per hour. \n\nMultiply by cosine of your latitude to see how fast the Earth is rotating where you are. \n\nHope you get an A if you are doing a science project haha.  Or hope you learned something :)

The Earth rotates once in 24 hours, and its (equatorial) radius is 3,963 miles (6,378 km). As with the Moon, the rotational speed starts at zero at either geographic pole and increases as you head toward the equator, where it reaches its maximum of about 1038 mi/hr (1669 km/hr). At 45 degrees north or south latitude, the rotational speed is about 0.7 of this maximum speed.

1. Earth's rotation is the reason we have days and nights. Without Earth rotating the sun would shine on one place only and the other side of the planet would be in the dark. Rotation is also the possible reason for its magnetic field.\n\n2. Earth's revolution is the reason for seasons and gravity.

As the earth rotates on its axis, the atmosphere is rotating with it.  Otherwise there'd be a constant wind, like in a fast-moving car on a still day,  as we were dragged through the atmosphere at the speed of the earth's rotation, yes?   And all winds would blow from east to west, and we know that's not the case.  \n\nBut the rotation of the earth does have an important effect on the weather.   A strange thing about rotating a globe is that a point on the equator has to move much faster to make it all the way around the waist of the globe in 24 hours than a point up around the Arctic circle has to move to make it all the way around the Arctic circle in 24 hours. (you can test this with a piece of string: The length of a piece of string wrapped around a globe at the level of New York is much shorter than a piece of string wrapped around the globe at the equator, right?)\n\n  You know that, looking at the globe with the sun behind your back, as the world turns, the continents pass off to the right (the east). New York crosses into the sun at dawn while San Francisco is still on the dark side of the globe.  Because the surface of the earth at the  equator is rotating faster than the surface of the earth 500 miles north of the equator, so is the air above it.  But the air above the equator isn't attached to the air above a point 500 miles north.  So the faster-moving and slower-moving air rub past each other.  This forms a kind of bow wave at the equator, like the wave that peels back from the bow of a boat as it moves through the water. Think of a big arrow pointing to the right and wrapped around  the equator.  So the air peels  back to either side of the equator, and forms a swirling current--curling counter-clockwise above the equator and clockwise below it.  This is called the coriolis wind.  It's one important factor in where weather comes from.

At Greenland. Because it is at the poles where the daily rotation os the earth is less effective. the day and night comes from the revolution of the earth.

Precession! The shape of Earth’s orbit becomes more or less oval (eccentricity), Earth wobbles as it spins (precession), and Earth's axis changes too (tilt). All these changes, over thousands of years, causes Earth's climate to change.
