The Science of Clouds

The video tutorial explores clouds, describing them as visible aerosols composed of water droplets, ice crystals, and other particles. It explains cloud formation as part of the water cycle, where water vapor condenses into droplets or ice crystals. Clouds are classified by altitude, with types like cirrus, altostratus, and nimbostratus indicating different weather conditions. Clouds also affect Earth's temperature by providing shade and are integral to weather prediction.

What are clouds primarily composed of?

• Only water droplets

• Just frozen crystals

• A mixture of liquid droplets, frozen crystals, and other particles

• Only dust and smoke

Why do clouds sometimes appear gray?

• They are made of dust

• They are too thin to reflect light

• They scatter and reflect less light as they become thicker

• They are closer to the ground

Which prefix is used for clouds formed above 20,000 feet?

• Cirrus

• Kumulus

• Stratus

• Alto

What type of weather do Nimbostratus clouds usually indicate?

• Windy weather

• Rainy or snowy weather

• Clear skies

• Sunny weather

How do clouds affect the Earth's temperature?

• They increase the temperature by trapping heat

• They only affect temperature during the night

• They provide shade and thus can lower the temperature

• They have no effect on temperature
