Think about the sidewalks near your home. Do you think there would be more or fewer cracks in a sidewalk in the desert? Why?

• Fewer. Sidewalks in the desert don't have as much root wedging or ice wedging.

• Fewer. Only ice wedging happens here, and there would never ever be any ice wedging in the desert.

• More. There is more root wedging in the desert.

• More. There is a lot of wind erosion in the desert to wear down the sidewalks.
