Watercycle

Water Cycle

The movement of water throughout the Earth.

Multiple Choice

Which statement best explains how the sun and the ocean interact to form a cumulonimbus cloud?

• Heat from the sun warms the ocean, causing water to evaporate. The water vapor then condenses to form a cumulonimbus cloud.

• Heat from the sun causes clouds in the area to gather over the ocean and form one large cumulonimbus cloud.

• Light from the sun shines on the ocean, causing water vapor to condense. The water then evaporates to form a cumulonimbus cloud.

• Light from the sun causes ocean water to reflect water vapor into the air and gather over the ocean into a cumulonimbus cloud.

Multiple Choice

The model shows where water can be found during the water cycle.

What should be added to the diagram to better explain the water cycle?

• Soil to trap water from runoff

• The sun to provide energy for evaporation

• Rocks to release thermal energy

• Plants to provide oxygen in the atmosphere.

Multiple Choice

The picture is a model of the water cycle. After the student places it near the sun, moisture forms on the inside of the cup.

What change is the student most likely observing in this model?

• Freezing

• Condensation

• The warming of air

• The formation of clouds

Multiple Choice

Which event in the water cycle is an example of water cooling and condensing?

• Clouds forming over the ocean.

• Clouds releasing rain over the ocean.

• Water evaporating from teh ocean into the air.

• Water flowing over the land into the ocean

Multiple Choice

A diagram of the water cycle is shown.

What process is represented by B?

• Evaporation, because water vapor is in the air

• Precipitation, because rain comes from clouds

• Condensation, because water is changing states to form clouds.

• Transpiration, because water is transforming.

Multiple Choice

A diagram of the stages in the water cycle is shown.

Which of these observations would most likely be seen at stage N?

• Water flowing downhill

• Fog forming along a highway

• The water level of a lake decreasing

• Dark clouds forming in the sky

Multiple Choice

The pictures show a sidewalk at different times.

Which table best describes the changes that most likely occurred between 6 am and noon?

• 6-7:Precipitation and runoff

  7-12: Condensation and Evaporation

• 6-7: Condensation and precipitation

  7-12: Runoff

• 6-7:Precipitation

  7-12: Condensation and runoff

• 6-7: Precipitation and runoff

  7-12: Evaporation

Multiple Choice

The diagram shows the process of evaporation. What is the most likely effect of this process on the land nearby?

• Increased drought conditions

• Decreased erosion of the shoreline

• Increased precipitation

• Decreased solar energy

Multiple Choice

Which statement describes a correct order of events in the water cycle?

• Runoff flows into the ocean, clouds form, and then the water condenses.

• Clouds form over the ocean, the vapor evaporates, and then vapor returns as precipitation.

• Rain falls over the ocean, the water condenses, and then water evaporates.

• Water from the ocean evaporates, the water condenses, and then the water falls back to Earth.
