What is the relationship between changes in air pressure and wind speeds?

A: When a high - and a low-pressure air mass are far apart, air moves quickly from low to high pressure.

B: When a high - and a low-pressure air mass are far apart, air moves quickly from high to low pressure.

C: When a high - and a low-pressure air mass are close together, air moves slowly from high to low pressure.

D: When a high - and a low-pressure air mass are far apart, air moves slowly from high to low pressure.

Complete Question:

Which of these best describes the relationship between changes in air pressure and wind speeds?

A: When a high - and a low-pressure air mass are far apart, air moves quickly from low to high pressure.

B: When a high - and a low-pressure air mass are far apart, air moves quickly from high to low pressure.

C: When a high - and a low-pressure air mass are close together, air moves slowly from high to low pressure.

D: When a high - and a low-pressure air mass are far apart, air moves slowly from high to low pressure.

E: The greater the difference in pressure, the faster the winds.

Answer: is Option E and Option D.

D: When a high and a low pressure air mass are far apart, air moves slowly from high to low pressure.

E: The greater the difference in pressure, the faster the winds.

The rules in the movement of the air masses is quite easy and simple. The air masses with high pressure always move towards the air masses with lower pressure. The wind speed is lower when the difference in the air pressure is very small. Similarly the wind is speed is faster when the difference in the air pressure is larger.

When air pressures are far apart with different pressures (low and high), there will be no movement of air, or a gradual slow movement occur resulting in slower wind speed.
