GEOLOGY

Detailed explanation-1: -Volcanoes are classified as active, dormant, or extinct. Active volcanoes have a recent history of eruptions; they are likely to erupt again. Dormant volcanoes have not erupted for a very long time but may erupt at a future time. Extinct volcanoes are not expected to erupt in the future.

Detailed explanation-2: -Extinct → Extinct volcanoes are those which have not erupted in human history. Examples of extinct volcanoes are Mount Thielsen in Oregon in the US and Mount Slemish in Co.

Detailed explanation-3: -Extinct volcanoes are the ones which have not been active from tens of thousands of years. So they are considered dead and are not expected to erupt in future whereas dormant volcanoes are the ones which have not erupted from a long time but are expected to erupt in the future.

Detailed explanation-4: -Volcanoes thought to be extinct have erupted again. For example, Mount Vesuvius erupted famously in AD 79, destroying the towns of Herculaneum and Pompeii. And the Soufriere Hills volcano on the island of Montserrat resumed activity in 1995.

Detailed explanation-5: -Ben Nevis, the tallest mountain in the United Kingdom. Hawaiian–Emperor seamount chain in the northern Pacific Ocean. Huascarán in Peru. Kyushu-Palau Ridge in the Philippine Sea. Mount Buninyong in Victoria Australia. Tamu Massif in the Northwest Pacific Ocean. More items
