Original Project
Weathering, Erosion, and Deposition
Item WE026004: Moving water continuously wears down earth's solid rock layer, which changes the shape of a valley even if you cannot see it happening.
Which of the following statements describes how long it takes for moving water to wear away the solid rock of a valley?
- It would take moving water about a hundred years or more to cause any change to the valley, no matter how small.
- It would take moving water millions of years or more to cause any change to the valley, no matter how small.
- Moving water continuously wears away the solid rock of a valley, which changes the valley even if you can’t see it happening.
- Moving water cannot wear away solid rock of a valley.
