πŸ”† Mantle Plume – Geography & Disaster Management

πŸ“ 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.

βœ… Key Features
πŸ”Ή Origin: Deep mantle or core-mantle boundary (~2,900 km depth)
πŸ”Ή Nature: Buoyant and hot, it melts the overlying lithosphere, forming volcanic hotspots
πŸ”Ή Examples:
β€ƒβž€ Hawaiian Islands – Pacific Plate moving over a plume
β€ƒβž€ Deccan Traps – Result of the RΓ©union plume

βœ… Importance
πŸ”Ή Explains intraplate volcanism (volcanoes away from plate boundaries)
πŸ”Ή Helps understand continental flood basalts and plate movements
