Where do the dust particles go when it rains?

When it rains, dust particles in the air are captured by raindrops. This process is known as "scavenging". Here's a step-by-step explanation:

1. As raindrops fall through the air, they collide with dust particles. This is due to the fact that dust particles are everywhere in the atmosphere.

2. When a raindrop collides with a dust particle, the dust particle becomes embedded in the raindrop. This is due to the wet nature of the raindrop and the adhesive forces between the dust and the water.

3. The raindrop continues to fall towards the ground, carrying the dust particle with it.

4. When the raindrop hits the ground, it bursts and the dust particle is released onto the ground.

5. Therefore, when it rains, dust particles are removed from the air and deposited on the ground. This is one of the ways that nature cleans the atmosphere.
