Some students noticed little trenches around the outside of the school building.

What do you think will happen to the trenches over time?

• The trench holes will get larger because the rain water will continue to push the soil out of the trench.

• The trench holes will disappear because rocks and soil will fill up from the bottom layer of the ground

• The trench holes will get smaller because grass will grow over the area and it will be watered by the rain.

• The trench holes will stay the same because they were made to catch the rain and control flooding.
