• weathering

• erosion

• deposition

• compaction

This rock formation took millions of year to be created. What conclusion can you draw about the center of this rock formation?

• Rain weathered the rock at the center because it was harder than the outer edges.

• Wind weathered the rock at the center because it was softer than the outer edges.

• Water flowed through the center of the rock and weathered it.

• The freezing and thawing of water weathered only the center of the rock.

Every year, Christmas trees are used to rebuild the sand dunes by the coast. What processes allow this to happen?

• erosion of sediment by water and weathering of sediment

• erosion of sediment by wind and deposition of sediment

• deposition of sediment by ocean waves and erosion of water

• weathering of sediment by ice and deposition of the sediment

How do sand dunes move?

• Wind blows sand over the edge of the dune and drops it on the other side.

• Wind moves the entire sand dune at once.

• Wind moves the bottom part of the sand dune.

• Wind picks up the sand dune and drops it somewhere else.

Students were conducting an experiment on wind erosion. They filled two boxes with soil. They added plants to one, and not the other. They then blew air on each box for 30 seconds and recorded their observations. What question were the students trying to answer?

• What effect do blow dryers have on the amount of erosion caused by water?

• What effect do plants have on the amount of soil erosion caused by wind?

• What effect does heat have on the amount of plant erosion?

• What kind of soil allows the most plant growth?
