Question

This is a picture of the Grand Canyon in USA. Between the gorge, flows the Colorado River. The gorge has been formed by weathering of rocks over millions of years. What do you think is the cause of the weathering?

Accepted Answer

The gorge which has been formed due to weathering is a result of change in weather conditions over a period of time.
In winters, the water seeps into the crevices of rocks and as the water freezes it expands and turns into ice. This expansion causes the cracks to become wider and deeper and as a result of this erosion of small stones occurs.

During rainy seasons, heavy rains causes water to rush down the cracks, further eroding the rocks and stones. As these, rocks crumble and fall away, they cause the widening of the gorge.

This weathering phenomenon has and resulted in the formation of gorge in the Grand Canyon.
