High/Low Pressure Questions

Front

What is a Low Pressure system?

Back

A Low Pressure system is an area where the atmospheric pressure is lower than that of the surrounding areas, leading to rising air, cloud formation, and precipitation.

Front

What is a High Pressure system?

Back

A High Pressure system is an area where the atmospheric pressure is higher than that of the surrounding areas, resulting in descending air, clear skies, and stable weather.

Front

How does air movement occur in a Low Pressure system?

Back

In a Low Pressure system, air moves upward and inward in a counter-clockwise spiral.

Front

How does air movement occur in a High Pressure system?

Back

In a High Pressure system, air flows downward and outward in a clockwise spiral.

Front

What happens to atmospheric pressure when moving towards the center of a High Pressure system?

Back

The surface atmospheric pressure increases when moving towards the center of a High Pressure system.

Front

What happens to atmospheric pressure when moving towards the center of a Low Pressure system?

Back

The surface atmospheric pressure decreases when moving towards the center of a Low Pressure system.

Front

What is the effect of descending air in a High Pressure system?

Back

Descending air in a High Pressure system experiences increasing atmospheric pressure, is compressed, and its temperature increases.

Front

What is the relationship between temperature and pressure in a Low Pressure system?

Back

In a Low Pressure system, as air rises, it cools and can lead to condensation and precipitation.

Front

What is the typical weather associated with High Pressure systems?

Back

High Pressure systems are typically associated with clear skies and stable weather conditions.

Front

What is the typical weather associated with Low Pressure systems?

Back

Low Pressure systems are often associated with cloudy skies, precipitation, and stormy weather.
