Understanding Clouds

Clouds are made of tiny water or ice droplets. They form when warm air rises and cools, causing water vapor to condense. Clouds can also form in mountainous areas. The dew point is the temperature at which vapor condenses. Condensation nuclei, like dust and salt, help form clouds. There are three main cloud types: cumulus, stratus, and cirrus, each with distinct features and weather implications.

What is the dew point in the context of cloud formation?

• The temperature at which water vapor condenses into droplets

• The altitude at which clouds form

• The amount of moisture in the air

• The speed at which warm air rises

What are condensation nuclei?

• Large water droplets that form clouds

• The temperature at which clouds form

• The process of warm air rising

• Particles like dust and smoke that water vapor condenses on

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

• Smoke

• Sunlight

• Dust

• Salt particles from ocean spray

What type of clouds are known for their white, puffy appearance?

• Cumulus clouds

• Nimbus clouds

• Stratus clouds

• Cirrus clouds

Which type of clouds are typically found at high altitudes and are made of ice crystals?

• Cumulus clouds

• Stratus clouds

• Cirrus clouds

• Nimbus clouds
