The difference between folding and faulting are discussed bellow:
- The horizontal movement of the earth’s crust results in folding.
- In shallow seas and lakes, deposited sediments (sedimentary rocks) generally get so compressed that they take the form of folds at many places resulting in complex structure. Called fold mountains. The process is known as folding.
- Examples. Himalayas in Asia and Rockeys in North America.
- The vertical movement of the earth’s crust involves uplift or subsidence of crust along the lines of weakness and is called faulting.
- The process of uplift and subsidence along the line of weakness is called faulting. The uplifted position may become Block Mountain and the subsided area may form deep Rift Valleys.
- Examples: Rift Valleys in East Africa. In India Narmada Valley is a Rift Valley.
