The Grand Canyon1 in Southwestern America,known as one of the seven wonders2 of the natural world,is a deep,ancient3 opening in the earth.It looks as if it formed as the earth split apart.But the canyon was cut by rivers.The rivers that carried dirt and pieces of stone slowly ate away the surrounding rock.For millions of years,the rivers turned and pushed.They cut deeper and deeper into the earth.They left a pathway4 of a great rocky5 opening in the earth that extended6 for hundreds of kilometres.
