Are many shapes and sizes and are arranged in many different combination.

›Mountains are actually regions of horizontal structure that have been eroded or dissected (cut up)
›Monadnocks- Mountains originally been a part of an igneous intrusion or strongly disturbed rock mass.
›Isolated summits
C. Mountains Of Erosional Origin

LIFE HISTORY OF MOUNTAIN
![Page 12: Relief of the Earth- Mountains and Valleys](https://reader036.vdocuments.net/reader036/viewer/2022070417/563dbb03550346aa9aa99295/html5/thumbnails/12.jpg)
› Lofty elevation
› Rugged , with irregular skyline and good scenery
› Steep slopes
› With young streams, narrow valleys, and deep ravines
› Frequent landslide, avalanches, and earthquakes.
YOUTH
![Page 13: Relief of the Earth- Mountains and Valleys](https://reader036.vdocuments.net/reader036/viewer/2022070417/563dbb03550346aa9aa99295/html5/thumbnails/13.jpg)
The characteristics of mature mountain are:
› Elevation not very high
› Rounded tops well covered with vegetation
› Slopes gentle
› Streams flowing slowly and the valleys wide
› Avalanche and earthquakes rare
Maturity

› They are characterized by:
› Low elevation, and what is left of them is called a peneplain or penoplane, meaning almost level like a plain
› Sometimes a peneplain- low rolling hills with an occational high hill called monadnock.
› Rivers moving slowly the land being almost level

Is an extended depression in the Earth surface that is usually bounded by hills or mountains and is normally occupied by a river or stream.
