Question

Quizplus · Accepted Answer

The Peninsular Ranges are primarily composed of igneous and metamorphic rocks that formed at great depths from the collision of tectonic plates. Sedimentary rocks are not as common in this area, and unconsolidated sand and gravel are typically found in fluvial and alluvial environments such as river beds and canyons rather than in the mountains themselves. There are some volcanic rocks present, but they are not the main type of rocks in the Peninsular Ranges.
