The video explains how temperature affects air pressure, leading to the formation of jet streams, which are powerful forces influencing weather patterns. It describes how jet streams can create different weather conditions across regions and discusses the Coriolis effect, which causes winds to curve. The video also covers Hadley and Polar cells, which are large air circulation patterns, and explains the concept of weather fronts, which are crucial for predicting weather changes.

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

• Cool air weighs more and creates low pressure.

• Cool air weighs less and creates low pressure.

• Warm air weighs less and creates low pressure.

• Warm air weighs more 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 about eight miles above the Earth.

• A wide band of slow-moving air in the lower atmosphere.

• A stationary band of air at the equator.

How do planes utilize the jet stream?

• They ride against it to slow down.

• They avoid it when traveling west.

• They ride with it to speed their journey west.

• They avoid it when traveling east.

What happens when the jet stream curves north?

• It speeds up and pushes air down to the ocean surface.

• It slows down and pushes air down to the ocean surface.

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

• It slows down and pulls up air from the ocean surface.

What are trade winds?

• Winds that blow directly north or south.

• Winds that flow toward the poles and curve east.

• Winds that flow toward the equator and curve west.

• Winds that flow away from the equator and curve west.

• A boundary between two masses of air with different temperatures.

• A boundary between two masses of air with different pressures.

• A boundary between two masses of air with the same temperature.

Why did Norwegians call the line where warm air arrived a 'front'?

• Because it resembled the front of a ship.

• Because it resembled the front of a building.

• Because it resembled the front of a train.

• Because it resembled the battlefronts of World War One.
