Answer:
The sun's heat causes differential heating of the earth's surface and water bodies causing changing wind patterns.
Step-by-step explanation:
The amount of sunlight received varies on various factors like
1. Insolation
2. Latitude
3. Altitude
Maximum sunlight is received at the equator while minimum sunlight is received at the poles.
Because of varying amounts of sunlight received, the surface and water bodies heat differently. This causes the wind over the surface to warm and cool differently.
The warm air being lighter in weight rises and is replaced by the heavier colder air. This leads to the formation of wind patterns.
The global winds are called trade winds.
