The grand canyon is a steep side canyon that is formed the Colorado rover in the state of Arizona and is a 277 mile long and is 29 km wide. The Colorado River established its course about 5 to 6 million years ago and since then has been cutting the tributaries and deepening the canyon.
The upliftment lined to the mountain formation later moved the sediments thousand feet upwards and created the Colorado plateau. Causing the temperatures in the northern rimland to decrease than in the southern rim due to its greater height above elevation.
As weather varies according to the elevations the forested rims have high snowfall but the temperature at the Colorado rover is warmer, about 1,737 species of vascular planet and fungi, lichens and others are found at 24,00 meters height.
That is because metamorphic rock is formed by parent rocks that are either sedimentary rock or igneous rocks and we can use the former rock type to distinguish the type of metamorphic rock, marble was igneous rock exposed to high pressure or temperature.
While the other two type of rocks are formed initially by sedimentation and volcanic movements and has no parent rocks.
