The wind from the desert pushing dust and smoke far out into the Pacific Ocean.

On Earth, wind is mostly the movement of air. In outer space, solar wind is the movement of gases or particles from the sun through space. The strongest winds seen on a planet in our solar system are on Neptune and Saturn.

Short bursts of fast winds are called gusts. Strong winds that go on for about one minute are called squalls. Winds that go on for a long time are called many different things, such as breeze, gale, hurricane, and typhoon.

Wind can move land, especially in deserts. Cold wind can sometimes have a bad effect on livestock. Wind also affects animals' food stores, their hunting and the way they protect themselves.

High winds can cause damage depending on how strong they are. Sometimes gusts of wind can make poorly made bridges move or be destroyed, like the Tacoma Narrows Bridge in 1940.[1] Power can go out because of wind, even if its speed is as low. This is because tree branches could change the flow of energy through power lines.[2] No species of tree can resist hurricane-force winds, but trees with roots that are not very deep can be blown over more easily. Trees such as eucalyptus, sea hibiscus, and avocado are brittle and are damaged more easily.[3]
