Answer:
Mountains provide for the freshwater needs of more than half of humanity, and are, in effect, the water towers of the world.
The world's mountains encompass some of the most spectacular landscapes, a great diversity of species and habitat types, and distinctive human communities.
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.
A upwarped mountain is a mountain consisting of a broad area of the Earth's crust that has moved gently upward without much apparent deformation, and usually containing sedimentary, igneous, and metamorphic rocks.
Fault-block mountains are formed by the movement of large crustal blocks when forces in the Earth's crust pull it apart.
Some parts of the Earth are pushed upward and others collapse down.
To understand a fault-block mountain, or sometimes referred as a “fault mountain”, you need to understand what a fault is.
Folded, or complex, mountains are created by intense compressional forces that fold, fault, and metamorphose the rocks, resulting in many of the world's biggest mountain belts, such as the Himalayas.
