Mountains can be characterized in several ways. Some mountains are volcanoes and can be characterized by the type of lava and eruptive history. Other mountains are shaped by glacial processes and can be characterized by their shape. Finally, many mountains can be characterized by the type of rock they are composed of.

Types of glacial mountains

Types of rock

• Igneous (see types of volcanoes, above)
