Atmospheric Pressure and Weather Systems

What is atmospheric pressure?

• The force exerted by the weight of water above us.

• The force exerted by the weight of air above us.

• The force exerted by the Earth's magnetic field.

• The force exerted by the sun's radiation.

How does atmospheric pressure change with increasing altitude?

• It increases.

• It decreases.

• It remains constant.

• It fluctuates unpredictably.

What happens to air at the Earth's surface in a low-pressure system?

• It sinks.

• It moves horizontally.

• It rises.

• It becomes stagnant.

What happens to air at the Earth's surface in a high-pressure system?

• It rises.

• It moves horizontally.

• It becomes stagnant.

• It sinks.

In which direction does air naturally flow?

• From low pressure to high pressure.

• From high pressure to low pressure.

• From areas of high temperature to low temperature.

• From areas of low humidity to high humidity.

What weather conditions are typically associated with high-pressure systems?

• Strong winds and heavy rain.

• Calm, clear, or sunny conditions.

• Rapidly circulating winds and precipitation.

• Thunderstorms and hail.

What weather phenomena are associated with low-pressure systems as air rises and cools?

• Calm and clear skies.

• Trapped fog or cloud.

• Clouds and precipitation.

• Decreased wind speed.

What are storms characterized as in terms of pressure?

• Deep areas of high pressure.

• Shallow areas of low pressure.

• Deep areas of low pressure.

• Areas with no significant pressure changes.
