Bailey's Big Back Yard: Air and Wind

The video explores the concept of wind, explaining that it is moving air caused by the sun's uneven heating of the Earth's surface. It discusses the properties of air, the causes of wind, and how wind speed and direction are measured. Different types of winds, such as trade winds and jet streams, are introduced, along with local wind patterns like sea breezes. The video concludes with a summary of key points and encourages further exploration.
