What causes winds ?

Explanation

### Step-by-Step Solution:

1. **Understanding Uneven Heating**: The Earth's surface does not heat evenly due to various factors such as the angle of sunlight, the type of surface (land or water), and the presence of vegetation. This uneven heating is the primary cause of wind.

2. **Air Temperature Changes**: When certain areas of the Earth's surface heat up, the air above these areas also heats up. As the air gets warmer, it becomes lighter and less dense.

3. **Rising Air**: The lighter, warmer air begins to rise. As this air rises, it creates a space where the air pressure is lower, known as a region of low pressure.
