why volcano somehow active and some volcano did not
Answers
Answer:
Volcanoes are formed by eruptions of lava and ash when magma rises through cracks or weak-spots in the Earth's crust. A build up of pressure in the earth is released, by things such as a plate movement which forces molten rock to exploded into the air causing a volcanic eruption.
LAVA – Lava is the liquid rock (magma) that flows out of a volcano. Lava glows red hot to white hot as it flows.
ACTIVE VOLCANO – An active volcano is one that erupts regularly.
DORMANT VOLCANO – A dormant volcano is one that has not erupted for many years, although there is still some activity deep inside.
A fissure vent, also known as a volcanic fissure, eruption fissure or simply a fissure, is a linear volcanic vent through which lava erupts, usually without any explosive activity. The vent is often a few metres wide and may be many kilometres long. ... Fissure vents are often part of the structure of shield volcanoes.
