What happens to water when it freezes and causes weathering?

• is shrinks and fills in cracks

• it flows downhill

• it expands and can make cracks in sidewalks larger

• rains and rubs against rocks

NGSS.MS-PS1-4

A student visited a nearby region and saw that a rock in the region had developed cracks in it. After two months, the student visits the same rock during the winter and finds that the cracks have widened, and ice has been deposited inside the cracks.

What process led to the change in the rock?

• physical weathering by water

• chemical weathering by ice

• erosion by moving water

• deposition by wind

A student walks to school on a sidewalk. At different points, the student observes large cracks in the sidewalk that are all near tall trees. The image shows one tree and the sidewalk cracks nearby.

What process likely formed the cracks, and what is the likely result of this process over time?

• Abrasion; the sidewalk breaks into smaller pieces

• Abrasion; the tree dies

• Tree root wedging; the sidewalk breaks into smaller pieces

• Tree root wedging; the tree dies
