what created the grand canyon?

Question

plain and simple?

or websites please

Answer 1

Erosion

Answer 2

As the Kaibab Plateau was uplifted the ancestral Colorado River had internal drainage and ended in the region of northeast Arizona. This created a huge lake and eventually the waters of this lake spilled over the Kaibab Plateau and started cutting the Grand Canyon. A variation of this idea is that the headwaters of the lower ancestral Colorado River breached the Kaibab Plateau and through Stream Piracy, diverted the upper Colorado River across the Grand Canyon.

Answer 3

Good answers here. One important thing to note is that the Colorado is in the southern desert like portion of the canyon. The northern 'side canyons' as they are sometimes called were created by runoff not from the colorado but by the snowmelt due to the higher elevations at the north end of the park. Bright Angel point at the Grand Canyon is about 8000' above sea level.

Answer 4

Plain and simple?
The Colorado river.

Over a long time the water flowing down the river (and its tributaries) has eroded away the rocks and created the canyon we see today. If you visit the hoover dam downstream of the grand canyon they speak of how the river is trying and beginning to succeed in finding its way around the man-made dam.

Answer 5

The Grand Canyon is believed to be a fissure through the Kaibab Plateau which developed as the plateau was thrust upward. Water flow through the canyon as it developed eroded the sides, smoothing them. There is evidence that the entire area was once seabed. Once the plateau surfaced, erosion by airborne grit continued the erosion process.

Answer 6

The uplift of a broad plateau where there was a river. The river remained at about the same level. The land rose around it.

Answer 7

The Colorado River over eons of eroding away the rock.

Answer 8
