Question

distinguish between fold and fault

Answer 1

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.

Answer 2

Hey there!


Fold Mountains:-


=>> Formed when earth’s two tectonic plates converge.

=>> The collision causes a part of the Earth’s surface to rise up.


=>> Compression creates a mountain.


=>> Example-Himalayas.


Fault Mountains:-


=>> Created along cracks and faults on the earth’s surface.


=>> The fault causes one block of the Earth to rift away from the other or moves the Earth’s block to move up or down.


=>> Convergence forms a mountain.


=>> Example : Sierra Nevada mountains.



hope it Helped!!!!!☺️
