1. A student placed some clean rocks in a clear plastic
jar. The jar was filled with clean water and covered
with a lid. Then the student shook the jar for five
minutes. The student noted that smaller pieces had
broken off some of the rocks and that there was a fine
grit on the bottom of the jar. Which change of Earth’s
surface was the student modeling?
A
B
C
D
Physical weathering
Chemical weathering
Erosion of sediments
Forming deltas

14. Tyrone put two stones in a plastic bottle of water and shook it. After he
stopped shaking the bottle, he observed that small pieces of the stones
were floating in the water. What is the best prediction he can make based
on this observation? If shaking the bottle causes pieces of stones to break
off—

then using cold water will break off more pieces.
B
then using hot water will make the stones change colors.
C
then shaking for a longer amount of time will break off more pieces.
D
then shaking for a shorter amount of time will make the rocks change
colors.
