A student placed a stack of rocks on a ramp. She added clumps of soil rooted with live grass. Using a garden hose, she then appl
ied a steady spray of water that soaked into the soil, making it heavier. What does the student's experiment model? A. Chemical weathering
B. Mass wasting
C. Wind erosion
D. Biological weathering
<span>The student's experiment is modeled after mass wasting, which is also known as mass movement or slope movement. One of the factors of mass wasting is gravity. The water from the hose weighs down the soil and causes the clumps of soil to move downward through the stack of rocks.</span>
