Water Cycle and Weather Concepts

The video tutorial covers the water cycle, explaining how water evaporates due to the sun's heat, forms clouds, and falls as rain, continuing the cycle. It also discusses snowfall, water shortages, and rainwater harvesting. Key terms like evaporation and water vapor are defined, and the importance of the water cycle in nature is emphasized.

What is the primary source of energy that drives the water cycle?

• Wind

• Earth's core

• Moon

• Sun

What is the process called when water changes into water vapor?

• Sublimation

• Condensation

• Precipitation

• Evaporation

How are clouds formed in the water cycle?

• By the rising of hot air

• By the melting of ice

• By the cooling of water vapor into droplets

• By the mixing of dust and air

What happens to water droplets in clouds before they fall as rain?

• They disappear

• They evaporate

• They freeze

• They become larger and heavier

• Water cycle

• Carbon cycle

• Oxygen cycle

• Nitrogen cycle

What causes snowfall in certain regions?

• Lack of sunlight
