What are 4 types of mountains?
Mountains are divided into four main types: upwarped, volcanic, fault-block, and folded (complex). Upwarped mountains form from pressure under the earth’s crust pushing upward into a peak. Volcanic mountains are formed from eruptions of hot magma from the earth’s core.
