a) With the aid of well labeled diagrams, describe how a fold mountain is formed.
b) Explain three positive effects of folding on the physical & human environment.

Answer Text:
a) - An extensive depression called a geosynclines is formed on the surface of the earth - The geosynclines is then filled with water to form a sea

- The surrounding land masses are eroded and resultant materials deposited in the geosyncline in layers
- Accumulation and weight of sediments causes the floor of the geosycline to subside further
- Further subsidence of the geosynclines triggers off
compressional forces drawing higher grounds close
- The layers of sediment in the geosynclines are the folded bending upwards forming mountains

c) - Fold mountains are often forested on their windward slopes and provide valuable
timber for construction
- The windward slopes receive rainfall hence supports agriculture
- Heavy rainfall and snow that collects in some fold mountains give rise to rivers which in turn provide water for both domestic &industrial use
- The process of folding could bring valuable minerals to the
surface cutting down the cost of mining e.g. coal
- The unique mountains and landscape attracts tourist thus earning the country foreign
exchange
