Wind forms primarily due to differences in atmospheric pressure caused by uneven heating of the Earth's surface by the sun. Because the Earth’s surface is made up of various land and water types, it absorbs solar energy at different rates, creating temperature differences in the air above. Warm air heats up, expands, and rises, which lowers the air pressure in that area. Cooler, denser air from surrounding higher-pressure areas then moves in to replace the rising warm air, creating wind

. This process can be summarized as follows:

• The sun unevenly heats the Earth’s surface, causing some areas to be warmer than others.
• Warm air rises, creating a low-pressure zone.
• Cooler air moves from high-pressure areas to low-pressure areas to balance the pressure difference.
• This movement of air from high to low pressure is what we experience as wind.

Additionally, the Earth’s rotation affects wind direction through the Coriolis effect, causing winds to curve rather than move in a straight line. Large- scale wind patterns are also driven by the temperature difference between the equator and the poles

. In short, wind is air in motion caused by the natural movement of air from high-pressure to low-pressure areas due to temperature differences and the Earth's rotation
