You can actually see the Grand Canyon from space. The Grand Canyon is 277 miles long, 18 miles wide at its widest, and more than a mile deep. The river that carved the Grand Canyon is the Colorado River, which is only 100 meters wide. The Mississippi and Amazon Rivers are far bigger, but neither have made a giant canyon. So how did this one canyon get so grand? The Colorado River is unique in that is transports 500,000 tons of silt and sand every day. And for every mile the river travels, it drops 10 miles down. While this river took care of carving away a deep slit in the canyon, gravity and weather helped make the Grand Canyon wider and wider. But that's not the end of the story: the Grand Canyon is getting deeper and wider every day.
