"As you descend down the Grand Canyon, the temperature rises."The rocks inside the canyon are constantly changing due to the plates found inside that cause magma to move around inside. The layers were formed by sand layers forming over each other belaboring the first layer with sand forming sand dunes(Pet 18-19).
