Water Cycle Concepts and Processes

The video explains the water cycle, highlighting the limited availability of fresh water on Earth. It covers key processes like evaporation, transpiration, condensation, precipitation, infiltration, and collection. The impact of human activities, such as building dams, on the natural water cycle is also discussed.

What percentage of Earth's water is available as fresh water for human use?

• Less than 1%

• 25%

• 50%

• 10%

What is the process called when water turns into vapor due to the sun's heat?

• Condensation

• Evaporation

• Precipitation

• Infiltration

How do plants contribute to the water cycle?

• By absorbing water from the atmosphere

• By storing water in their roots

• By converting water into oxygen

• By releasing water vapor through their leaves

What happens to water vapor as it rises and cools in the atmosphere?

• It condenses to form clouds

• It becomes part of the soil

• It evaporates

• It turns into snow

What is the term for rain, hail, sleet, and snow falling from clouds?

• Infiltration

• Precipitation

• Transpiration

• Evaporation

What is the process called when rainwater seeps into the ground?

• Infiltration

• Collection

• Evaporation

• Condensation

What is the purpose of building dams in the context of the water cycle?

• To enhance precipitation

• To prevent transpiration

• To store and manage water

• To increase evaporation

What is the term for the human intervention in the natural water cycle through structures like dams?

• Artificial water cycle

• Managed water cycle

• Natural water cycle

• Controlled water cycle
