GEOLOGY

Detailed explanation-1: -Volcanologists use that term as shorthand for “potentially active, ” so a “dormant” volcano is one that is not erupting now, but that is considered “active” because it could erupt in the future. Mount Hood is an active volcano that is currently dormant. Kīlauea is an active volcano that is currently erupting.

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.

Detailed explanation-3: -A volcanic eruption is when lava and gas are released from a volcano-sometimes explosively. The most dangerous type of eruption is called a ‘glowing avalanche’ which is when freshly erupted magma flows down the sides of a volcano.

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.
