GEOLOGY

Detailed explanation-1: -An active volcano is one which has recently erupted and there is a possibility that it may erupt soon. A dormant volcano is one that has not erupted in a long time but there is a possibility it can erupt in the future.

Detailed explanation-2: -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. Inside an active volcano is a chamber in which molten rock, called magma, collects.

Detailed explanation-3: -Stratovolcanoes are more likely to produce explosive eruptions due to gas building up in the viscous magma. Andesite (named after the Andes Mountains), is perhaps the most common rock type of stratovolcanoes, but stratovolcanoes also erupt a wide range of different rocks in different tectonic settings.

Detailed explanation-4: -Dormant → Dormant volcanoes are volcanoes that have not erupted in a long time but are expected to erupt again in the future. Examples of dormant volcanoes are Mount Kilimanjaro, Tanzania, Africa and Mount Fuji in Japan.

Detailed explanation-5: -Mauna Loa Erupts The largest active volcano in the world, Mauna Loa, erupted for about 12 days in late 2022, the first eruption since 1984.
