How does the shape of a volcano relate to the average viscosity of the eruptive products of that volcano?
Answers
Answer:
The explosive bursting of bubbles fragments the magma into clots of liquid that cool as they fall through the air. These solid particles become pyroclasts or volcanic ash. Clouds of gas and tephra that rise above a volcano produce an eruption column that can rise up to 45 km into the atmosphere.
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.
extinct volacanoes are called dead volcanoe
