FAQs on Audio Notes: पृथ्वी की पपड़ी Video Lecture - यूपीएससी सीएसई के लिए भूगोल (Geography) - UPSC
| 1. What is the composition of the Earth's crust? |  |
Ans. The Earth's crust is primarily composed of a variety of rocks and minerals. The two main types of crust are continental crust, which is thicker and primarily composed of granitic rocks, and oceanic crust, which is thinner and mainly composed of basaltic rocks. Key minerals found in the crust include feldspar, quartz, mica, and amphibole.
| 2. How thick is the Earth's crust, and does it vary? | |
Ans. The thickness of the Earth's crust varies significantly. On average, the continental crust is about 30 to 50 kilometers thick, while the oceanic crust typically ranges from 5 to 10 kilometers in thickness. This variation is due to geological processes such as tectonic activity and sediment deposition.
| 3. What are the major geological processes that shape the Earth's crust? | |
Ans. The Earth's crust is shaped by several geological processes, including plate tectonics, erosion, sedimentation, and volcanic activity. Tectonic movements can lead to the formation of mountains, earthquakes, and the creation of new crust at mid-ocean ridges, while erosion and sedimentation shape the landscape over time.
| 4. What are some significant features of the Earth's crust? | |
Ans. Significant features of the Earth's crust include mountains, valleys, plateaus, and ocean basins. Major mountain ranges, such as the Himalayas and the Andes, are formed by tectonic forces, while valleys and plains can result from erosion and sedimentation processes. Ocean basins are formed by the movement of tectonic plates and the accumulation of sediments.
| 5. How does the Earth's crust interact with the mantle? | |
Ans. The Earth's crust interacts with the mantle at the Mohorovičić discontinuity, commonly known as the Moho. This boundary marks the transition from the crust, which is composed of lighter, silica-rich rocks, to the denser, more molten rocks of the mantle. This interaction is crucial for geological processes such as magma formation and the movement of tectonic plates.
