The bulk of the rock exposed in the walls of the Grand Canyon are sedimentary, derived from sediments that originated from shallow, mid-ocean, or deep ocean depositions, from a constantly invading and receding inland ocean which has long-since ceased to exist. Some layers display evidence of windblown deposition, and deep layers are igneous and metamorphic, the roots of ancient mountains.

Scientists divide rocks into groups based on what?
Rocks are grouped by how they are formed. There are 3 types of rocks. Sedimentary, Metamorphic, and Igneous rock. Sedimentary rocks are made from broken down rocks, called sediment, which come from all three rocks. Metamorphic rocks come from existing rocks that are changed by heat and pressure. The Igneous rocks are formed from magma that rose up to the surface, also known as lava. When the lava cools and hardens it forms igneous rocks. That is a rock cycle.
