Detailed explanation-1: -Answer: 1. Dormant and extract are the stages of volcanic activity.

Detailed explanation-2: -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.

Detailed explanation-3: -Volcano eruptions go through several stages typically beginning with earthquake swarms and gas emissions, then moving to initial steam and ash venting, lava dome buildup, dome collapse, magmatic explosions, more dome growth interspersed with dome failures and finally, ash, lava and pyroclastic eruptions.

Detailed explanation-4: -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-5: -Active-A volcano is active if it is erupting, or may erupt soon. Dormant-A dormant volcano is one that may have erupted before, but it is no longer erupting. Extinct-An extinct volcano is not erupting and will never erupt again. 23-Mar-2022
