Understanding Wind Movement and Influences

What is the term used to describe the force created by differences in air pressure?

• Pressure gradient force

• Gravitational force

• Coriolis force

• Frictional force

How does the spacing of isobars on a map affect wind strength?

• Closer isobars indicate weaker winds

• Wider isobars indicate stronger winds

• Closer isobars indicate stronger winds

• Isobar spacing does not affect wind strength

Which factor affects wind direction only when it is close to the Earth's surface?

• Friction

• Pressure gradient force

• Coriolis effect

• Magnetic field

What causes the Coriolis effect?

• Sun's radiation

• Ocean currents

• Earth's rotation

• Earth's gravitational pull

In the Northern Hemisphere, how do winds behave around high-pressure centers?

• Converge in a clockwise direction

• Diverge in a counterclockwise direction

• Converge in a straight line

• Diverge in a clockwise direction
