GEOLOGY

Detailed explanation-1: -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. Inside an active volcano is a chamber in which molten rock, called magma, collects.

Detailed explanation-2: -Some volcanoes, like the infamous Yellowstone supervolcano, may lie dormant for hundreds of thousands of years between eruptions.

Detailed explanation-3: -A dormant volcano is one that is “sleeping” but could awaken in the future, such as Mount Rainier and Mount Fuji. An extinct volcano is “dead”-it hasn’t erupted in the past 10, 000 years and is not expected to ever erupt again. Kohala on the Big Island of Hawaii could be considered an extinct volcano.

Detailed explanation-4: -Well that depends on the volcano. Some volcanoes erupt very often (and some like Kilauea almost never stop). On the other hand, some volcanoes are inactive for very long periods of time between eruptions.
