Science: How Water Changes Land Erosion and Deposition for Young Learners

A rainstorm washes loose soil from the top of a hill down to the bottom. Is this an example of erosion or deposition? Explain your answer.

A river slows down and drops sand along its bank. Is this erosion or deposition? Explain your answer.

Fill in the blank: Erosion is when water, wind, or ice picks up and moves soil, sand, or rocks. Deposition is when those materials are ______ in a new place.

Which would probably cause more erosion on a bare dirt hill: a light sprinkle or heavy rain? Explain why.

A stream carries small rocks, sand, and leaves after a storm. Then the stream becomes slower and leaves a pile of sand near a bend. What happened when the stream slowed down?

Circle the place where deposition is most likely to happen: fast water rushing down a steep hill or slow water spreading out on flat land. Explain your choice.

A student says, "Water can only change land during floods." Is the student correct? Explain your answer.

Put these events in order from 1 to 3: water flows down a hill, water picks up loose soil, soil is dropped at the bottom of the hill.
