Question

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.

Answer 1

In low pressure, air rises and rotates fast in the high atmosphere, forming fast winds. In high pressure, the air sinks instead of rising, forming slow-moving air currents or slow wind. A low pressure system brings rain, snow, and high winds, while a high-pressure system brings cold air.

Answer 2

Answer: Option A

Explanation: When a high- and a low-pressure air mass are far apart, air moves quickly from low to high pressure. This is because air moves from areas of low pressure to areas of high pressure due to differences in air pressure.
