Question

Sleeping volcanoes are referred as
(A) Active volcanoes
(B) Dormant volcanoes
(C) Extinct volcanoes
(D) None of these

Answer 1

Hint : A volcano is a crack in a planetary-mass object's crust that permits hot lava, volcanic ash, and gases to escape from a magma chamber under the surface, such as Earth. Volcanoes are most often found on Earth when tectonic plates are diverging or converging, and the majority of them are located underwater. For example, divergent tectonic plates create volcanoes along a mid-oceanic ridge like the Mid-Atlantic Ridge, but convergent tectonic plates create volcanoes in the Pacific Ring of Fire.

Complete Step By Step Answer:
An inactive volcano is one that hasn't erupted in over 10,000 years yet has the potential to do so. Volcanoes that are no longer active are known as dormant or sleeping volcanoes. Despite lying inactive for thousands of years, these volcanoes are anticipated to erupt again at some point. Mount Fuji and Mount Rainier are two examples of dormant volcanoes.
Volcanoes that have been dormant for a long time yet may erupt again are known as dormant volcanoes. It's tough to tell the difference between active and dormant volcanoes. Mount Fuji, for example, has been labelled as dormant or inactive by some scientists. Since its last eruption in 1707, the volcano has been dormant, yet it is still designated as active. Mount Fuji is one of the active volcanoes on Honshu, according to the Japanese Geological Survey. An active volcano that is not erupting but is expected to erupt again is known as a dormant volcano.
Hence option B is correct.

Note :
The three most prevalent popular categories of volcanoes are subjective, and several volcanoes that were assumed to be extinct have erupted once again. Countries have created new categories to characterise the various degrees and phases of volcanic activity to assist prevent people from incorrectly assuming they are not at risk when living on or near a volcano. To denote the different stages, some alert systems employ various numerals or colours. Colors and words are used in other systems. Some systems employ a mix of the two.
