In what direction does the force produced by the Coriolis effect act?

The Coriolis effect is an apparent deflection of moving objects when they are viewed from a rotating reference frame.
Perhaps the most commonly encountered rotating reference frame is the Earth. Moving objects on the surface of the Earth experience a Coriolis force, and appear to veer to the right in the northern hemisphere, and to the left in the southern. Exactly on the equator, motion east or west, remains (precariously) along the line of the equator. Initial motion of a pendulum in any other direction will lead to a motion in a loop. Movements of air in the atmosphere and water in the ocean are notable examples of this behavior: rather than flowing directly from areas of high pressure to low pressure, as they would on a non-rotating planet, winds and currents tend to flow to the right of this direction north of the equator, and to the left of this direction south of the equator. This effect is responsible for the rotation of large cyclones.

What direction do dust devils rotate?
They can turn either direction in either the north or south hemisphere, as they are too small to be affected by the Coriolis Force.
What is the effect of the earths daily rotation?

How does the coriolis effect affect astronauts in space?
Because astronauts orbiting the earth rotate around it much faster than the rest of us (once every 90 minutes or so rather than once a day) the effect of the Coriolis effect would be correspondingly stronger. Ordinarily, this force would still be too weak for astronauts to notice. However, because astronauts feel "zero gravity" (because they are falling towards the earth at the same rate as their ship) there are some situations in which the Coriolis effect might be more obvious to them; for example, objects floating in midair might slowly float back and forth* with a period equal to the ship's orbit time. *Technical discussion follows* Objects would actually follow elliptical or sinusoidal paths, and this floating effect would actually be a combination of three different effects: the Coriolis effect, along with the "centrifugal force", and the actual gravity of the earth. Whereas the Coriolis force depends on the velocity of a moving object, the last two effects vary slightly according to the radial distance from the center of the earth, and would therefore be most noticeable above or below the center of gravity of the spacecraft. For example, an astronaut resting above the spacecraft's center of mass would first begin falling (very slowly) towards the earth due to the decrease in centrifugal force with greater turning radius. Once moving, the astronaut would be affected by the Coriolis force, and pushed (very slowly) towards the front end of the spacecraft. Maximum drift speeds wouldn't exceed 1 cm/s for the even the largest rooms in the international space station. That said, I'm not an astronaut, and I don't know if astronauts have ever noticed this faint effect or not. I just did the math.
Why do the toilets flush counterclockwise in the northern hemisphere and clockwise in the southern hemisphere?
Here is a simple definition of the "coriolis effect" from Wikipedia: Perhaps the most commonly encountered rotating reference frame is the Earth. Moving objects on the surface of the Earth experience a Coriolis force, and appear to veer to the right in the northern hemisphere, and to the left in the southern. Movements of air in the atmosphere and water in the ocean are notable examples of this behavior: rather than flowing directly from areas of high pressure to low pressure, as they would on a non-rotating planet, winds and currents tend to flow to the right of this direction north of the equator, and to the left of this direction south of the equator
What does force do to objects?
•An action (transfer of energy) that will accelerate a body in the direction of the applied force.
What effect will a reduction in surface wind speed have on the Coriolis force?
The effect that a reduction in surface wind speed will have on the Coriolis force is to reduce the effect of the Coriolis force. Winds blowing at higher speeds are pulled on more by the Coriolis force, which somewhat alters the direction in which they blow.
At which location does the coriolis force have the least effect on wind?
The Coriolis effect has the least effect on winds in equatorial regions and the most effect on winds in polar regions. Coriolis effect deflects winds to the right of their initial direction in the northern hemisphere and left of their initial direction in the southern hemisphere.
What is the effect that causes objects to moved in a curved direction due to earth rotation?
Coriolis force
What is the effect that causes objects to move in a curved direction due to to earths rotation?
It's called Coriolis force.
What is the effect that causes object to move in a curved direction due to the earths rotation?
It's called Coriolis force.
What is the effect that causes objects to move in curved direction due to the earths rotation?
Easy it's the coriolis force
What apparent curving of the paths of winds and ocean currents is the result of the rotation of the earth?
The Coriolis effect is caused by the rotation of the Earth and the inertia of the mass experiencing the effect. This force causes moving objects on the surface of the earth to be deflected in a clockwise sense (with respect to the direction of travel) in the Northern Hemisphere and in a counter-clockwise sense in the Southern Hemisphere.
What is the effects produced by a force on a body?
coriolis
What affect will a reduction in surface wind speed have on the Coriolis force?
The surface wind speed has no effect on the Coriolis Force. The Coriolis Force is dependant on the rotation of Earth that has the effect on surface wind and not the other way around
What force is responsible for wind?
The Coriolis Effect
What is the force that deflects wind?
The Coriolis effect is the force that deflects prevailing winds
This effect is a force created by rotating bodies?
The equivalent of force, for rotational movement, is called torque.
