Inside Our Planet: Earth’s Interior & The Rock Cycle Explained | Geography

Have you ever wondered what lies deep beneath our feet? 🌍 From the surface we walk on to the scorching center of the planet, join SH LearninGyan as we take a journey to the center of the Earth!
In this video, we break down the Internal Structure of the Earth and explain how rocks are constantly changing forms through the Rock Cycle. This topic is essential for Geography students, NCERT learners, and aspirants of competitive exams like UPSC, SSC, and State PSCs.

📝 What we cover in this video:
The Crust: Continental vs. Oceanic crust (SIAL and SIMA).
The Mantle: The Asthenosphere, Lithosphere, and convection currents.
The Core: Outer Core (Liquid) vs. Inner Core (Solid) and NIFE.
Discontinuities: Mohorovicic, Gutenberg, and Lehmann discontinuities.
The Rock Cycle: How Igneous, Sedimentary, and Metamorphic rocks transform into one another.

📚 Key Concepts:
Lithosphere: The rigid outer part of the earth, consisting of the crust and upper mantle.
Asthenosphere: The highly viscous, mechanically weak, and separating region of the upper mantle of the Earth.
