   Chip a large block of ice into smaller pieces and pile them up.

• D.

   Move a large block of ice slowly across a tray filled with dirt and rocks.

• Frost wedging from cold environment splits a rock into pieces

• Rain washes soil down a hill

• Dust storms carry small bits of soil

• Warmth from the sun causes water to evaporate.

• Water condenses in the atmosphere.

• Precipitation falls to earth.

• Water collects on Earth's surface until it evaporates.

Kendrick collects observations about the role of the sun’s energy in the water cycle. He makes a drawing of the sun’s role. What should Kendrick draw to describe how the sun’s energy flows on and above Earth’s surface? Choose TWO correct answers.

• A.

  water from a river collecting in lake

• B.

  moving water on a lake becoming still

• C.

Mrs. Banks is investigating how water cycles through the water cycle. She makes a computer model to show how the matter in a snowflake moves through the water cycle. Step 1 and Step 6 of the model are the same: Snowflakes fall from the sky.

Which descriptions match step 2 in Mrs. Banks's model?

Choose from the answers below:

Snowflakes land on a pond.

Snowflakes melt into drops of water.

Energy from the sun evaporates the pond water.

Water vapor condenses into snow clouds.
