FAQs on GC Leong: The Earth's Crust Video Lecture - Geography for UPSC CSE

1. What is the Earth's crust made of?
Ans. The Earth's crust is primarily composed of rock and minerals. It consists of a variety of elements such as oxygen, silicon, aluminum, iron, calcium, sodium, and potassium.
2. How thick is the Earth's crust?
Ans. The thickness of the Earth's crust varies depending on its location. On average, the oceanic crust is thinner, ranging from 5 to 10 kilometers (3 to 6 miles), while the continental crust is thicker, ranging from 25 to 70 kilometers (15 to 43 miles).
3. What are the two types of crust found on Earth?
Ans. The Earth's crust is divided into two types: oceanic crust and continental crust. Oceanic crust is denser and thinner, mainly composed of basalt, while continental crust is less dense and thicker, consisting of granite rocks.
4. Can the Earth's crust move?
Ans. Yes, the Earth's crust is constantly moving due to tectonic plate movements. This movement occurs due to the convection currents in the underlying mantle, causing the crustal plates to collide, separate, or slide past each other.
5. How do earthquakes occur in the Earth's crust?
Ans. Earthquakes occur when there is a release of energy along tectonic plate boundaries. The stress built up between the plates due to their movement is suddenly released, resulting in seismic waves that shake the Earth's crust. This release of energy causes the ground to shake, leading to an earthquake.
