The Grand Canyon, located in the Grand Canyon National Park in Arizona, was created approximately 5 million years ago from the Colorado River. The Grand Canyon is 277 miles long, up to 18 miles wide, and reaches a depth of over a mile.
What interaction between Earth’s systems was MOST likely responsible for the creation of this landmark?

A Erosion of rock from the water.

The Grand Canyon is a prime example of erosion likely resulting from the passage of water. Wind abrasion would be able to wear down weak structures, such as those made of sandstone, but would do little to severely impact compacted earth. Landslides impact temperate, rainy climates and would not play a part in the desert of Arizona. Tectonic fissures, or earthquakes, can create sinkholes and other gaps in solid land, but could not create something as large as the Grand Canyon.
