Question

Distinguish between folding and faulting

Answer 1

Differences between folding and faulting:

Folding:

• They are caused due to horizontal movements.
• They are also caused due to compression (various folds are formed).
• Mountains are formed (Fold Mountains).
• They have a common center.

Faulting:

• They are caused due to vertical movements.
• They are also caused due to tensions and faults among rocks.
• Mountains are formed (Block Mountains).
• They do not have a common center (they move away).

Hope it helps :)

Answer 2

★Answer★

✔Folding

(i) Folding is caused due to horizontal movements.

(ii) Forces move towards a common centre.

iii) Due to compression, different types of folds are formed.

(iv) It leads to the formation of anticlines and synclines.

(v) They are generally common in sedimentary rocks, e.g., the Himalayas and the Alps.

✔Faulting

(i) it is caused generally due to vertical movements.

(ii) Forces move away from the common centre.

(iii) Due to tension, faults occur along which displacement of rocks take place.

(iv) It leads to the formation of Block Mountains and Rift valleys, due to upliftment and subsidence of land.

(v) They are generally common in Igneous or Metamorphic rocks, e.g., Vosges and Black forest are Block Mountains and the river Rhine flows through the rift valley. In India, river Narmada and Tapi flow through a rift valley.
