A geologist examines rock in a canyon wall and sees that the rock is made up of small grains of sand that are stuck together. The sand appears to be from a granite formation about 100–200 miles upriver from the canyon. The granite formation was formed directly from a cooling magma body. Based on this information, what types of rock are the canyon wall and granite formation?

The canyon wall is sedimentary rock because it is composed of grains of sand that have been cemented and compacted together. The granite formation is an igneous rock because it formed from cooled magma.
