What is the name of the extinct volcano which overlooks the city of Edinburgh?

Answer 1

Arthur's Seat!
The remains of a volcano that erupted under water during the Carboniferous period, Arthur's Seat is located within Holyrood Park in the centre of Edinburgh. Although only 250m (823 feet) in height, Arthur's Seat is a notable landmark, dominating the city. Known also as the Lion's Head, Arthur's Seat is the highest of a series of peaks which take the form of a crouched lion.

Geologically what remains is a basalt lava plug that choked the neck of a volcano which would have been active around 335 million years ago. The action of glaciation has cut into its heart, making it one of the most accessible exposures of an ancient volcano.

Two stony banks on the east side of the hill represent the remains of an Iron Age hill-fort and a series of cultivation terraces are obvious above the road just beyond. In 1836, just below the summit, seventeen minature wooden coffins each containing a carved figure were found in a small cave. Their existence has never been satisfactorily explained; associations with witchcraft have been suggested or perhaps they were memorial to the seventeen victims of the infamous William Burke (1792 - 1829) and William Hare (died c. 1860).

Answer 2

There are two ways a volcano can become extinct. One is if the lava supply is cut off or if the plate that the volcano is on subducts underneath another plate. Both of these things occur because the crust (all the land and ocean floor) are made up of plates that set above a liquid layer known as the outer core. All of these plates move, but very slow usually one 1-2 millimeters a years. The volcano is created when magma(lava before it reaches the surface) seeps up through fissures in the mantle(layer between the crust and outer core) and crust. The magma builds up and creates the volcano. But as the plates move, the volcano can move away from the magma source, thus it is no longer a volcano. When two plates collide with each other one will go under the other, this is called subduction. The plate that goes under melts in the outer core, thus a volcano on a subducting plate would be destroyed, causing it to become extinct.
