Exploring Air Pressure and Weather Patterns

How does warm air compare to cool air in terms of weight and pressure?

• Cool air is heavier and creates low pressure.

• Cool air is lighter and creates low pressure.

• Warm air is lighter and creates low pressure.

• Warm air is heavier and creates high pressure.

What is a jet stream?

• A slow-moving current of air near the Earth's surface.

• A narrow band of fast-moving air high above the Earth.

• A warm air mass moving from the tropics.

• A circular motion of air at the poles.

Why do airplanes try to avoid the jet stream when traveling west?

• To save fuel.

• To avoid turbulence.

• To avoid storms.

• To reduce travel time.

What happens when the jet stream curves north?

• It causes the air to sink.

• It slows down and cools the air.

• It speeds up and pulls up air from the ocean surface.

• It creates a high-pressure area.

What is the Coriolis effect?

• The formation of jet streams.

• The movement of air from high to low pressure.

• The rotation of the Earth causing winds to curve.

• The creation of trade winds.

What are Hadley cells?

• Loops of air that circle the Earth.

• Bands of fast-moving air.

• Regions of low pressure at the equator.

• Areas of high pressure at the poles.

What is a polar cell?

• A mass of warm air at the equator.

• A circular motion of cold air at the poles.

• A fast-moving current of air.

• A high-pressure area in the temperate zone.

What is a front in meteorological terms?

• A low-pressure area.

• A fast-moving air current.

• A boundary between warm and cool air masses.

• A high-pressure area.

Why did Norwegians call the boundary between warm and cool air a 'front'?

• Because it caused storms.

• Because it resembled a military battlefront.

• Because it was a new discovery.

• Because it was a high-pressure area.

How do meteorologists use weather maps?

• To predict where it will rain.

• To measure air pressure.

• To track the jet stream.

• To identify trade winds.
