Question

Geographical reason soft rocks form folds while hard rocks form faults​

Answer 1

Answer:

Faults form in rocks when the stresses overcome the internal strength of therock resulting in a fracture. A fault can be defined as the displacement of once connected blocks of rock along afault plane. This can occur in any direction with the blocks moving away from each other.

Answer 2

Answer:

As explained under.

Explanation:

• A fold occurs when the flat surface of the sedimentary rock is bent as a result they crack and split and hence get weak, the weak cracks that develop are called faults, they may straight or zigzag.

• These folks are formed by the stress that moves up and down the rocks as and hence creates the structures the soft rocks get easily folded and compressed as they are flexible and have the ability to bend forwards and  as the folds in the rocks are seen in the layered strata of rocks of sediments more as compared to the igneous rocks .

• Faults are formed by the friction produced in the hard rocks i.e the secondary tectonic activity in the earth's crust. The formation of the tunnel the slope s thus a characteristic of the hard and thickness of the rocks that are displaced by the earth's internal processes.
