Weather in Action: Cloud Formation

The video explains the concept of condensation nuclei, which are particles in the air that water vapor condenses around to form water droplets. These nuclei can come from various sources such as dust, smoke, and salt particles from ocean spray. When water droplets gather, they form clouds. The video also introduces different types of clouds.

What are condensation nuclei?

• Particles that create wind

• Particles that absorb sunlight

• Particles that serve as a base for water droplets

• Particles that repel water

Which of the following is NOT a source of condensation nuclei?

• Ocean spray

• Smoke

• Sunlight

• Dust

What happens when water vapor condenses on condensation nuclei?

• It turns into gas

• It evaporates

• It forms tiny water droplets

• It forms ice crystals

What is formed when large nuclei of droplets come together?

• Rain

• Fog

• Clouds

• Snow

Which of the following best describes the process of cloud formation?

• Water droplets evaporate into the air

• Sunlight heats the air

• Condensation nuclei dissolve

• Large nuclei of droplets combine
