Expansion and conduction – Did you know?

The video explains how heat haze occurs when air near the ground heats up, expands, and rises. This process bends and distorts light rays, creating a shimmering effect known as heat haze.

What is a possible consequence of the air near the ground being warmer than the air above?

• Decrease in air pressure

• Formation of clouds

• Creation of a heat haze

• Increase in humidity

What happens to the air close to the ground when it heats up?

• It contracts and falls

• It remains static

• It expands and rises

• It cools down quickly

How does the rising warm air affect light rays?

• It amplifies them

• It bends and distorts them

• It reflects them

• It absorbs them

What visual effect is created by the distortion of light rays due to warm air?

• A heat haze

• A mirage

• A rainbow

• A shadow

Which of the following is NOT a result of air expansion near the ground?

• Rising of air

• Shimmering effect

• Cooling of air

• Distortion of light
