Question

Which of the following statements are incorrect for coriolis force?

1) In the Northern Hemisphere, wind from high-pressure systems pass low-pressure systems on the left so counter-clockwise movement.

2) The Coriolis force applies to movement on rotating and the stationary objects.

3) It is determined by the mass of the object and the object's rate of rotation.

4) The Coriolis force is perpendicular to the object's axis.

5) The Coriolis force is zero at the Equator.

In the Northern Hemisphere, wind from high-pressure systems pass low-pressure systems on the right. This causes the system to swirl counter-clockwise. Low-pressure systems usually bring storms. This means that hurricanes and other storms swirl counter-clockwise in the Northern Hemisphere. In the Southern Hemisphere, storms swirl clockwise.

The invisible force that appears to deflect the wind is the Coriolis force. The Coriolis force applies to movement on rotating objects. It is determined by the mass of the object and the object's rate of rotation. The Coriolis force is perpendicular to the object's axis. The Earth spins on its axis from west to east. The Coriolis force, therefore, acts in a north-south direction. The Coriolis force is zero at the Equator.
