Big Idea 1 and 2 Quick Checks

Water can move small rocks quickly along the bottom of a fast-flowing river. As they move, the rocks bump into and scrape against each other. Some of these rocks may settle at the bottom of the river as the water slows down. Here the rocks may become covered with sediments that pile up. Which of the following represents the weathering of these rocks?

• The bumping and scraping of the rocks.

• The movement of the rocks along the river.

• The settling of the rocks at the bottom of the river.

• The covering of the rocks with sediments that pile up.

Codi was investigating how rocks can change. She carried out the following procedure.

1. 1. Place several sugar cubes in a jar.

2. 2. Seal the jar and shake it 50 times.

3. 3. Dump the sugar cubed on a piece of black paper.

4. 4. Compare the appearance of the sugar cubes to their original size and shape.

What process was Codi studying?

• erosion

• weathering

• sedimentation
