As the water rushes along the ground, it picks up sand, gravel and small rocks, which can help the water erodes deep paths known as channels. If a river passes over a high ground, it can cut a narrow valley with sides like steep cliffs. This kind of valley is known as ‘river gorge’ or canyon’. The largest river gorge in the world is ‘Grand Canyon’ in Arizona in south-western United States formed by Colorado River. It is 28.8 kilometres (18 miles) wide and 1.8 kilometres (1.125 mile) deep. Five million people visit the Grand Canyon every year.
