Wind is the movement of air caused by changes in pressure in our surroundings.

Concept: The main cause of air movement is the differences caused by pressure and temperature. The air in warm temperature rises in an upward direction, whereas the air in cold temperature is thick and moves over and replaces the warm air.

The miracle is known as wind.Wind due to Differences in PressureThe movement of air that occurs due to the difference in temperature and pressure is due to wind. 

When the difference of pressure occurs between two places, a pressure grade is created which enables the air to move from the high- pressure region to the low- pressure region. 

The movement of air doesn't do in the quickest straight- line path and follows a spiralling route, which is outwards from high pressure and inwards towards low pressure
