🔆 Mantle Plume – Geography & Disaster Management

📍 A mantle plume is a localized, upwelling column of hot magma rising from deep within the Earth’s mantle, possibly from the core-mantle boundary. These plumes are thought to be stationary and independent of tectonic plate boundaries.

✅ Key Features
🔹 Origin: Deep mantle or core-mantle boundary (~2,900 km depth)
🔹 Nature: Buoyant and hot, it melts the overlying lithosphere, forming volcanic hotspots
🔹 Examples:
 ➤ Hawaiian Islands – Pacific Plate moving over a plume
 ➤ Deccan Traps – Result of the Réunion plume

✅ Importance
🔹 Explains intraplate volcanism (volcanoes away from plate boundaries)
🔹 Helps understand continental flood basalts and plate movements
