Condensation nuclei, tiny particles of matter in the air, are important because ________.
kolbaska11 [484]

Condensation nuclei which are tiny particles of matter in the air are important as they provide a surface for water vapors to form water molecules on it.

<h3>What is Condensation Nuclei?</h3>

It is defined as the tiny particles in the surrounding atmosphere where water vapor condenses to form a water droplet or ice particle.

The water vapor in the atmosphere needs something to stick to for condensation to occur

Condensation nuclei are the particles floating in the atmosphere which include dust, dirt, forest fire ash, factory smoke and pollution, volcanic ash, salt from ocean spray, and sulfate particles that are emitted by phytoplankton.

On land, Grass, twigs, and windshields act as the surface for water vapor on which they condense to form dew and frost.

Likewise, the Condensation Nuclei act as a surface in the atmosphere.

Thus, Condensation Nuclei are important as they provide a surface for the water vapors to condense and form water molecules like water droplets and ice particles.
