The Water Cycle and the Ocean's Role

Kelly is showing his class how liquid water in his water cycle model can be changed into another state. What will happen when he adds heat to the liquid water in his water cycle model?

• it will condense

• it will evaporate

• it will form clouds

• it will attract dust particles

Meredith is looking at a drawing of one of the steps in the water cycle. Which of the following steps describes step D?

• Water vapor rising in the air

• Water vapor is condensing into a liquid.

• Liquid water is warmed by the sun

• Precipitation is falling back to Earth

What part of Jacob's and Angelina's model represents cloud formation in the water cycle?

• Water sitting in the bottom of the bottle

• tiny drops of water forming at the top of the bottle

• drops of water running down the side of the bottle

• the lamp shining on the bottle of the water

Each morning, Owen notices dew on the grass while he takes a walk. Dew is small water droplets that are stuck to the blades of grass. Owen knows that it did not rain the night before. What best explains why the grass is wet in the morning?

• the heat from the moon caused the water in the soil to evaporate

• liquid water from the soil flowed up to the top of the grass

• water vapor in the air condensed when it touched the cool grass

• water from a leaky pipe sprayed the grass

Which of the following must happen to water in order for it to evaporate off the surface of lakes and oceans during the water cycle?

• the water must be in motion to start the process of evaporation

• the Sun must warm the water enough so that some water molecules turn to gas

• the movement of wind must be strong enough to pull small water drops into the air

• the water temperature must decrease enough to cause some water molecules to turn to gas

What part of Ashley's model represents precipitation in the atmosphere?

• droplets forming on the pan

• water vapor rising from the beaker

• water drops falling from the pan

• water heating inside the beaker

In the model, the water droplets will fall directly into the water at the bottom of the tank.

How can this water cycle model be changed or modified to demonstrate runoff?

• Remove the glass cover so the water vapor can escape the tank, just like the water vapor escapes the Earth's atmosphere

• put a hose into the tank so that water flows out just like a river flows across the surface of the Earth

• Runoff can NOT be demonstrated in a model of the water cycle

• add something, like a bucket, to the bottom of the tank just below the ice cubes so the water drops will fall on top
