KCSE Geography Paper 1 2011 Section B Question 8.

Extensive shallow depressions called geosynclines develop on the earth’s surface.
Prolonged and extensive erosion occurs on the surrounding higher grounds.
Sediments are deposited in the geosyncline forming thick layers.
The weight of the sediments causes subsidence of the geosyncline leading to accumulation of more sediments to great thicknesses.
Further subsidence of the geosyncline triggers off compressional forces which cause the sediments to fold.
The folded layers of sediments in the geocyncline are thrust upwards to form fold mountains, along the edges of a geosyncline due to closeness to the source of forces.

Fold mountains are sources of rivers that provide water for generation of H.E.P /domestic use/irrigation/industrial use.
Fold mountains are often forested and provide timber which is used in the building and construction industry/medicinal/aesthetic/wildlife habitat.
Some fold mountains have exposed valuable minerals deposits which are mined.
Fold mountains are tourist attractions/snow covered slopes encourage sporting activities, thus earning countries foreign exchange.
The wind ward slopes of fold mountains receive heavy precipitation which enhances agricultural activities.
The rugged nature of some fold mountain landscapes hinder human settlement/agricultural activities.
The leeward slope of some fold mountains create rain shadow effect which result into aridity discouraging crop farming/encourages livestock farming.
Some fold mountains may act as barrier to transport and communication/make the construction of transport and communication lines difficult/expensive.
