What are the key characteristics of a geological hotspot and how do they form volcanic chains?

Hey Philly, good to see you again. Here are the characteristics of hotspots: Stationary Source*: The hotspot remains relatively fixed while tectonic plates move over it. Volcanic Chains*: As a plate moves, it forms a chain of volcanoes. Older volcanoes are farther from the hotspot. Age Progression*: Rocks become progressively older with distance from the active hotspot. Basaltic Magma*: Most hotspots produce basaltic lava, which is less viscous and flows easily. Long-lived Activity*: Hotspots can remain active for millions of years. Send me the next one 📸
