Mountain are the large land form formed by nature. Mountains are colder than lower ground, because the Sun heats Earth from the ground up.
Mountains usually have steep, sloping sides and sharp or slightly rounded ridges and peaks.
Mountains can be rocky and barren. Some have trees growing on their sides and very high mountains have snow on their peaks.he height of the feature makes it either a hill or, if higher and steeper, a mountain. The absolute heights of features termed mountains and hills vary greatly according to an area's terrain.
The major mountains tend to occur in long linear arcs, indicating tectonic plate boundaries and activity. Mountains exist on every continent and even beneath our great oceans. Rock that does not fault may fold, either symmetrically or asymmetrically. The upfolds are anticlines and the downfolds are synclines; in asymmetric folding there may also be recumbent and overturned folds. Mountains are home to approximately one-tenth of the world’s people
