Mantle Plumes and Hotspots | UPSC | Geography | Geology | NET | GATE | PCS

#geography #upsc #civilservices #csirnet #geology #gate a hotspot is an area of the Earth’s mantle from which hot plumes rise upward, forming volcanoes on the overlying crust. n much the same way that plumes rise buoyantly in a lava lamp, plumes of mantle magma (molten rock) are theorized to rise buoyantly from a source within Earth’s deep mantle. When such a plume rises into the shallow mantle, it partially melts and the melt may then rise to the surface where it can erupt as a hotspot volcano. Hotspot volcanism is distinct in that it does not originate from processes that produce the more common submarine volcanism that occurs at boundaries of Earth’s tectonic plates. https://t.me/+VOV8D-rq687H0dRr Telegram link
