STF : a. Volcanism is a type of exogenetic process. b. Up folds or anticlines are found in Block mountains.

Question

1. Volcanism is a type of exogenetic process.
2. Up folds or anticlines are found in Block mountains.
3. The geomorphic process responsible for the formation of alluvial plains is aggradation.
4. The Chhotanagpur plateau is an example of dissected plateau.
5. The plates which form the ocean beds are called continental plates.

1. True; Volcanism is an exogenetic process because it involves the release of magma, ash, and other materials onto the Earth’s surface from deep within the Earth.
2. False; Block mountains are formed by the uplift and tilting of large blocks of rock along faults, but they do not typically have up folds or anticlines.
3. True; Alluvial plains are formed by the deposition of sediment carried by rivers, which is a type of aggradation.
4. True; The Chhotanagpur plateau in eastern India is an example of a dissected plateau because it has been extensively eroded by rivers, resulting in a dissected landscape of ridges, valleys, and waterfalls.
5. False; The plates which form the ocean beds are called oceanic plates, while continental plates form the Earth’s continents.
