Weathering, Erosion, and Deposition
Small changes to the surface of the earth caused by wind and water can add up to large changes over long periods…
Item WE063001: Wind wore away the solid rock of valleys millions of years ago and continues to wear away the solid rock of valleys today.
Which of the following is TRUE about the wearing away of the solid rock of valleys by wind?
- Wind wore away the solid rock of valleys in the past but wind is no longer able to wear away the solid rock of valleys today.
- Wind wore away the solid rock of valleys millions of years ago and continues to wear away the solid rock of valleys today.
- Wind wears away the solid rock of valleys today but did not wear away the solid rock of valleys millions of years ago. The valleys we see have been worn away by wind only in the last few hundreds of years.
- Wind did not wear away the solid rock of valleys in the past and is not wearing away the solid rock of valleys today. Valleys stay the same over time.
