How is wind formed?


  Air in motion is called as motion. But from where does wind come from? How does is get into motion? And how is wind formed?

  Sun rays heat up the Earth's surface everyday. They do so evenly but it happens very unevenly. During the day, air present above land heats up much faster as compared to air present above the surface of rivers and oceans. This results in the creation of different air pressures. The heated air above land expands and rises up. The cooler air from the oceans rushes in and takes its place, resulting in a sea breeze. This is how wind is formed.

  But the other way round, at night, temperature of land drops, making oceans relatively warmer than land, hence air above oceans expands and rises up. The cooler air from land rushes in to take its place, resulting in a land breeze. In this way, wind is born.
