GEOLOGY

Detailed explanation-1: -Volcanic activity ranges from emission of gases, non-explosive lava emissions to extremely violent explosive bursts that may last many hours. The types of eruptions determine the relative volumes and types of volcaniclastic material and lava flows, consequently the shapes and sizes of volcanoes.

Detailed explanation-2: -Overall, 46 volcanoes were in continuing eruption status as of 19 December 2022. An eruption marked as “continuing” does not always mean persistent daily activity, but indicates at least intermittent eruptive events without a break of 3 months or more.

Detailed explanation-3: -Complete answer: Option B) Dormant volcanoes are volcanoes that have not erupted in a long time but are likely to erupt again in the future. Examples of dormant volcanoes are Mount Kilimanjaro in Tanzania, Africa, and Mount Fuji in Japan.

Detailed explanation-4: -Ash. Fine particles of pulverized rock that are blown from an explosion vent. Basalt. The most common type of rock formed from the cooling of lava. Caldera. Dormant volcano. Extinct volcano. Fumerole. Lahar. Lava. More items •01-Oct-2004
