Short Questions on Mountain Building

1) In which book Kober described about Geosynclinal Theory?
Answer : Kober has described about Geosyncline Theory on his book "Der Bau Der Erde".

2) What is Geosyncline?
Answer : According to Kober, There were mobile zones of water in the places of present day mountains. He called this mobile zones of water as Geosynclines or orogen.

3) What is Kober's Geosyncline Theory based on?
Answer : Kober's Geosyncline Theory is based on the forces of contraction produced by the cooling of the earth.

4) What was Kober's main objective in developing Geosyncline Theory?
Answer : Kober's main objective was to establish relationship between ancient rigid masses or tabulanced and more mobile zones.

5) What is Kratogen?
Answer : The geosynclines are long and wide mobile zones of water which are surrounded by some rigid masses which have been named as kratogen or forelands by Kober.

6) Name the stages through which process mountain building passes.
Answer : According to Kober, the whole process of of mountain building passes through three closely linked stages of lithogenesis, orogenesis and gliptogenesis.

7) What is lithogenesis?
Answer : The preparatory stage of mountain building is called lithogenesis.

8) What is sedimentation?
Answer : Sedimentation is the process in which insoluble heavy particles in liquid are allowed to settle down at the bottom.

9) What is randketten?
Answer : The parallel ranges formed on the either side of the geosyncline have been termed as randketten by Kober.

10) What is zwischengebirge?
Answer : The middle portion of the geosyncline remains unaffected by the folding activity. This unfolded middle portion is called zwischengebirge.

11) Which landmasses surrounds tethys geosyncline?
Answer : According to Kober, Tethys geosyncline was surrounded by European landmass in the north and African rigid masses in the south.

12) How was Alpine mountain chains formed?
Answer : According to Kober, Alpine mountain chains were formed because of compressive forces coming from both north and south side.

13) Give and example of median mass.
Answer : Mediterranean sea between Pyrenees-Provence ranges, Anatolian plateau between Pantic and Taurus ranges, etc are some examples of median mass.
