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 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 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.
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).

What direction do tornadoes rotate in the northern hemishpere?

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.
Do tornadoes rotate differently?

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 most tornadoes rotate in the northern hemisphere?
It is due to the temprature of northern hemisphere is very cold due to this reason torandoees does not exhibit in the northern hemisphere.
