In today’s video, we dive deep into the science behind volcanic eruptions—connecting NCERT fundamentals with current affairs.
We begin with the structure of the Earth — Crust, Mantle and Core — and scientifically explain why temperature increases as we go deeper. This forms the base for understanding volcanic activity.
We then explore:
🔸 How magma forms & rises
🔸 Why volcanoes erupt (pressure, gases, viscosity, tectonic settings)
🔸 Types of lava — acidic, basic & intermediate
🔸 Major volcanoes of the world (from NCERT & G.C. Leong)
🔸 Volcanic landforms important for UPSC
To connect science with current relevance, we discuss the recent Hyali Gubbi volcanic eruption and understand how volcanic ash clouds impact aviation, jet engines and flight routes — a key link to UPSC GS-I (Geography) and GS-III (Disaster Management).
This video is designed to be evergreen:
✔ Strong NCERT base
✔ Linked to The Hindu current affairs
✔ Scientific clarity for UPSC Prelims + Mains
✔ Real-world relevance (aviation + global impact)
If you are preparing for the UPSC IAS Exam, this is your one-stop conceptual guide to volcanoes.
