How was Aurthur's seat formed?

Arthur's Seat, an extinct volcano located in Edinburgh, Scotland, was formed around 350 million years ago during a period of volcanic activity. The structure is primarily composed of volcanic rock, including basalt and other igneous materials. Over time, erosion and glacial activity shaped the landscape, leaving behind the prominent hill we see today. Its distinctive topography offers panoramic views of the surrounding area, making it a popular hiking destination.
