Understanding the Water Cycle

What is the primary role of the water cycle in the environment?

• To provide a continuous supply of fresh water for all living organisms.

• To create clouds in the sky.

• To increase the temperature of the Earth.

• To reduce the amount of water in the oceans.

During the evaporation phase, what happens to the water?

• It turns into ice.

• It becomes water vapor due to heat from the sun.

• It remains in the ocean.

• It falls as rain.

What occurs during the condensation phase of the water cycle?

• Water droplets evaporate into vapor.

• Water vapor remains unchanged.

• Water droplets freeze into ice.

• Water vapor turns into tiny water droplets.

What causes precipitation to occur in the water cycle?

• Water droplets become too big and heavy.

• The sun heats the water droplets.

• Water vapor rises higher into the sky.

• Water droplets freeze.

What is the purpose of the 'Simulation Ops' in the water cycle?

• To demonstrate the water cycle on a small scale.

• To increase the speed of evaporation.

• To stop the water cycle.

• To create artificial rain.

Why does water without a divider evaporate faster in the simulation?

• It has a larger exposed surface area.

• It is colder than the other water.

• It is closer to the sun.

• It is mixed with salt.

In the terrarium setup, what is one source of water vapor?

• Water from the clouds.

• Water in the moist soil.

• Water from the rain.

• Water from the ocean.

What process describes water loss from plants in the terrarium?

• Condensation

• Precipitation

• Evaporation

• Transpiration

What is the result of the distillation process in the water cycle?

• Saltwater is turned into fresh water.

• Water is turned into ice.

• Water is turned into vapor.

• Salt is dissolved in water.

What happens to the salt during the distillation process?

• It dissolves in the fresh water.

• It turns into a gas.

• It remains as a solid in the flask.

• It evaporates with the water.
