How would a three hour time exposure photograph of stars in the northern sky appear if earth did not rotate?
The stars would be brighter points of light. Without the Earth's rotation, the Earth would not be moving enough to create the lines of light that ordinarily appear in an uncorrected stationary time exposure. Depending on the clarity of the sky, the entire image could be grayed by scattered light (light pollution).
What else can I help you with?
What is it called when the paths of winds and ocean currents seem to curve because of the earths rotation?
It's called the 'Coriolis effect'. In the northern hemisphere, they rotate clockwise. South of the equator, they rotate counter-clockwise.
How can you rotate Widdy Dart Board inner cicle?
You can't rotate only the inner circle. You can rotate the entire Widdy Board by grabbing it on both sides and moving it in the direction you want to rotate it.
Does Saturn rotate on its axis?
Yes. All planets rotate about an axis.
When you click rotate left on the drawing toolbar to rotate a graphic in a document how many degrees does it rotate 30 60 90 180?
It rotates 90 degrees.
What is the adjective for rotation?
The word revolve (to go around, as in circles) can mean to turn, spin, or rotate. (*For planets, "revolve" is used to mean orbiting around a larger body, while "rotate" is used for the spin of the body itself.)

How would a three hour time exposure photo of stars in the northern sky appear if the earth did not rotate?
The photograph would record far more stars, nebulae, and galaxies than the naked eye could see. There are many thousands of such photographs to be seen on the web. Any camera capable of long exposures with an equatorial mount and a clock drive could create such a photograph. A clock drive, which turns the right ascension axis of the mount at the speed of a hour hand (hence the name), counteracts the rotation of the Earth.
In which direction do cassiopeia and the big dipper rotate around the north star?
Cassiopeia and the Big Dipper appear to rotate counterclockwise around the North Star in the northern hemisphere.
What direction do tornadoes rotate in the northern hemishpere?
The vast majority of tornadoes in the northern hemisphere rotate counterclockwise.
Do the stars in the constellation Ursa major appear to rotate clockwise or counterclockwise?
In the Northern Hemisphere, when facing North, towards the Pole Star (Polaris) Ursa Major and surrounding constellations, rotate counter-clockwise (right to left).Turn round to face south (with Polaris behind you) the stars rotate clockwise (left to right).
How would the moon appear to an observer on earth if the moon did not rotate?
it would still appear to rotate
How would the moon appear to an observe on earth if the moon did not rotate?
it would still appear to rotate
Do most tornadoes in the northern hemisphere rotate in a clockwise or a counterclockwise direction?
Most tornadoes in the northern hemisphere, at least 99%, rotate counterclockwise.
How do hurricanes rotate in both Southern and Northern hemispheres?
Yes. By definition a hurricane must rotate, however, they rotate in opposite directions. Storms in the northern hemisphere rotate counterclockwise while those in the southern hemisphere rotate clockwise.
What is the name of the northern star?
The northern star is called Polaris. It is located almost directly above the North Pole and remains relatively stationary while the other stars appear to rotate around it.
Do typhoons rotate clockwise?
In the northern hemisphere, typhoons rotate counter-clockwise. In the southern they rotate clockwise. This is due to the force of the rotation of the Earth.
How are tropical storms in the northern hemisphere different from tropical storms in the northern hemisphere?
Tropical storms in the northern hemisphere rotate counterclockwise while those in the Southern Hemisphere rotate clockwise.
