there was a big river or ocean that cut away the ground, but the water level dropped
If I'm not mistaken, lava didn't really shape the grand canyon, the Colarado River did. It slowly eroded the rock until it is the massive canyon we know today.
the shape and size of it
erosion
because it shape the rocks because the rocks were originally sand
Some people think its fascinating because of its shape size or color.
The grand canyon was formed when excessive and massive overflow of water washed off soft and loosen sandstone and dirt leaving hard ground intacted. As water continue down stream, soft sandstone and dirt get washed off and this created deeper channel as water decreases. At the same time water waves created and separated strata layers by bouncing and washing off loosen dirt between layers, making horizontal lines all the way from the top to the bottom. These horizontal lines prove that water did flood the area creating a massive canyon. A small river would not be able to create a several miles wide canyon. The fact that the top and bottom strata layers look identical in age suggests that the canyon may have been created at the same or not too distant set of times.
They shape the earth into the natural wonders you see today like the Grand Canyon
it is a big plastic bridge in the shape of a U the is hanging of the edge of the grand canyon. :D
The Grand Canyon is very like a 'V' in shape. Although, at the bottom, there is a river bed which would cause it to look more of a squared 'U' >>> \_/ Would look similar.

Well The Grand Canyon has it's shape because of the heat, Basicly the rock minerals are affected by the heat causing them to grow in wich the become like mountains that's probably it hope this helps
The Palo Duro canyon was formed from water erosion from the prairie dog town branch of the Red River. Wind and water erosion deepened and widened the canyon to the shape we see today.
