Exploring the Water Cycle with Bill Nye

What is the water cycle also known as?

• Aqua circle

• Water loop

• Hydro circle

• Hydrological cycle

What does the term 'hydro' in hydrological cycle stand for?

• Hydration

• Water

• Hydrogen

• Cycle

What is the process called when water turns from liquid to vapor?

• Precipitation

• Collection

• Evaporation

• Condensation

What happens to water vapor when it cools down?

• It condenses into liquid

• It turns into ice

• It disappears

• It evaporates

What is precipitation?

• Water flowing in rivers

• Conversion of vapor to liquid

• Water falling from clouds as rain, snow, sleet, or hail

• Water rising as vapor

What role do molecules play in the evaporation process?

• They dissolve other substances

• They move faster and escape as vapor

• They slow down and condense

• They bond together to form water

Why is condensation important in the water cycle?

• It produces energy

• It keeps the oceans full

• It forms clouds and returns water to Earth

• It helps plants grow

What experiment did Bill Nye use to explain condensation?

• Heating water in a pan

• Using a cloud chamber

• Creating a cloud with a pump and smoke

• Freezing water in a freezer

How does condensation contribute to cloud formation?

• It heats the water vapor

• It splits water molecules

• It pushes water vapor upwards

• It cools and condenses water vapor into droplets
