Scientists discover a 220‑mile‑wide ‘hot blob’ beneath New Hampshire, drifting towards NYC

Scientists find a huge hot rock area under New Hampshire. This Northern Appalachian Anomaly (NAA) is very hot and located deep down. It formed when Greenland separated from North America. The hot rock is moving slowly westward. In millions of years, it might be under New York City. This discovery helps us understand Earth's hidden processes.
