Gopher tortoises live on dry land. They live in large holes that they dig in the soil. How does the behavior of the gopher tortoise cause physical weathering? A.It loosens the soil, allowing more water to reach the rocks underground. B.It erodes the soil by moving it from underneath the ground to above ground. C.It moves rocks above ground, where they are exposed to more water and wind. D.It causes exfoliation of the rocks as the tortoise breaks the rocks into smaller pieces.
B. It erodes the soil by moving it from underneath the ground to above ground.
