Understanding the Water Cycle

What is the first step of the water cycle?

• Condensation
• Precipitation
• Transpiration
• Evaporation

How does water turn into water vapour?

• Water turns into water vapour via filtration.
• Water turns into water vapour by freezing.
• Water turns into water vapour through evaporation.
• Water turns into water vapour through condensation.

What is condensation, and how does it help form clouds?

• Condensation occurs when liquid water evaporates into vapor.
• Clouds are formed by the freezing of solid particles in the air.
• Condensation happens only in winter when temperatures drop.
• Condensation helps form clouds by converting water vapor into liquid droplets when air cools.

What experiment can you do at home to see condensation in action?

• Boil water and watch the steam rise.
• Place a warm glass in the freezer.
• Leave a bowl of water in the sun.
• Fill a glass with ice water and observe the condensation on the outside.

What happens when clouds become too heavy to hold water?

• Precipitation occurs.
• The clouds float higher into the atmosphere.
• The clouds turn into ice crystals.
• The clouds dissipate into thin air.

How does rainwater return to rivers, lakes, and oceans?

• Rainwater is stored in underground tanks.
• Rainwater is absorbed by plants only.
• Rainwater returns to rivers, lakes, and oceans through surface runoff and groundwater flow.
• Rainwater evaporates into the atmosphere.

What is transpiration, and how does it affect rainfall?

• Transpiration is the absorption of water by roots.
• Transpiration is the process by which plants release water vapor, affecting rainfall by increasing atmospheric moisture that can lead to precipitation.
• Transpiration has no impact on weather patterns.
• Transpiration is the process of photosynthesis in plants.

What are the three main processes of the water cycle?

• Sublimation, filtration, evaporation
• Transpiration, filtration, evaporation
• Evaporation, condensation, precipitation
• Condensation, runoff, infiltration
