FAQs on Mountain Building Process (Orogeny) & Types of Mountains Video Lecture - UPSC
| 1. What is mountain building? |  |
Ans. Mountain building, also known as orogeny, is the geological process that leads to the formation of mountains. It involves various tectonic forces and processes that cause the Earth's crust to buckle, fold, and uplift, resulting in the creation of mountain ranges.
| 2. What are the types of mountains formed through orogeny? | |
Ans. There are three main types of mountains formed through orogeny:
a) Fold Mountains: These mountains are formed when rock layers are compressed and folded, creating long ridges and valleys. The Himalayas and the Appalachians are examples of fold mountains.
b) Fault-Block Mountains: These mountains are formed when blocks of the Earth's crust are uplifted along faults. The Sierra Nevada Mountains in the United States are an example of fault-block mountains.
c) Volcanic Mountains: These mountains are formed through volcanic activity, where molten rock (magma) rises to the surface and solidifies. The Andes in South America and the Cascade Range in the United States are examples of volcanic mountains.
| 3. What are the main tectonic forces involved in mountain building? | |
Ans. The main tectonic forces involved in mountain building are:
a) Convergent Boundaries: When two tectonic plates collide, they can form mountains. This occurs when one plate is forced beneath the other in a process called subduction. The collision of the Indian and Eurasian plates is responsible for the formation of the Himalayas.
b) Divergent Boundaries: When two tectonic plates move away from each other, magma rises to fill the gap, creating new crust and volcanic mountains. The Mid-Atlantic Ridge is an example of a divergent boundary where volcanic mountains form.
c) Transform Boundaries: When two tectonic plates slide past each other horizontally, they can generate intense earthquakes but typically do not form mountains.
| 4. What are the geological processes involved in mountain building? | |
Ans. The geological processes involved in mountain building include:
a) Folding: This process occurs when compressional forces cause rocks to bend and fold, leading to the formation of fold mountains.
b) Faulting: When rocks break along fractures called faults, it can lead to the uplift of fault-block mountains.
c) Volcanism: The eruption of magma onto the Earth's surface can create volcanic mountains.
d) Erosion: While erosion does not directly form mountains, it plays a significant role in shaping their appearance over time by wearing down the rocks and exposing the underlying structures.
| 5. Can you explain the concept of isostasy in relation to mountain building? | |
Ans. Isostasy is the concept that explains the balance between the Earth's lithosphere (the rigid outer layer) and the underlying asthenosphere (the more fluid layer). When mountains are formed through processes like uplift and erosion, they exert pressure on the lithosphere. In response, the asthenosphere flows to support the excess weight, causing the lithosphere to rise. This equilibrium between the lithosphere and asthenosphere is known as isostatic adjustment. Isostasy plays a crucial role in maintaining the stability and equilibrium of mountain ranges.
