Shaping of the Earth's Surface | Chapter 2 Social Science Class 9 | ONE SHOT | CBSE 2026-27
Unlock the secrets of our changing planet! 🌍 In this One Shot session, we cover the entire Chapter 2: Shaping of the Earth’s Surface for Class 9 Social Science, strictly following the CBSE 2026-27 New Draft Syllabus. We dive deep into the "Endless Dance" of internal and external forces. From the deep heat of the Earth's core to the relentless power of wind and water, learn how our world is constantly being rebuilt and resized. What you will learn in this video: • The Builders (Endogenic Forces): How internal heat creates mountains and ocean floors. • The Earth’s Interior: Understanding the Crust, Mantle (Asthenosphere), and Core. • Plate Tectonics: Why India is crashing into Eurasia at 5cm/year to build the Himalayas!. • The Sculptors (Exogenic Forces): The difference between Weathering (breaking) and Erosion (moving). • Landform Creators: How rivers make V-shaped valleys , glaciers carve U-shaped valleys , and winds build mushroom rocks. • Coastal Wonders: The cycle of sea caves, arches, stacks, and beaches. • The Geomorphic Cycle: How the Earth recycles itself from sea floor to mountain peak.
