With the aid of a well labelled diagrams, describe how a fold mountain is formed
Answer:
-An extensive depression called a geosycline is formed on the surface of the earth
-The geosycline is filled with water to form a sea
Diagram:
-The surrounding land masses are eroded and the resultant materials are deposited in the geosycline in layers
-Accumulation and weight of sediments causes the floor of the geosycline to subsidise further.
-Further subsidence of the geosycline triggers off compressional forces, drawing higher grounds close
-The layers of sediment in the geosycline are then
folded bedding upwards to form mountains
