TYPES OF MOUNTAINS
Presented bySinju ccBed Geography
Are land form have height of 900 Km or more from sea level.
The name for the processes that collectively produce a mountain belt is orogenesis
MOUNTAINS
Based on its origin there are
1) Fold mountains2) Block mountains3) Volcanic mountains4) Residual mountains
TYPES OF MOUNTSINS
Formed due to folding of crustal rocks by compressive force.
They are young mountains. Sediments are found up to great depth. Are highest and most extensive mountains. Generally found along the margins of continents. E.g. Himalaya, Rockies, Andes, Atlas etc
FOLD MOUNTAINS
FOLD MOUNTAINS
Known as fold block mountains. Formed due to faulting by compressive force. Represent the up standing parts of the ground between
two fault or either side of a rift valley. Also called horst mountains E.g. Vosges, Black forest mountain, Rhine Rift valley.
Block mountains
Block mountains
Formed by the accumulation of volcanic materials. Based on the mode eruption different types of volcanic
mountains are formed. E.g. Kilavea volcano in southern Hawaii Island
Stromboli volcano in Lipasari island.
Volcanic mountains
Volcanic mountains
Formed due to difference in weathering process. The upper layer of the rock is removed. Hard rock remained as residual mountains. E.g. Aravalli range, Nilgiri range
