and which hurls its ashes high into the atmosphere. The term volcano can either mean the vent from which magma erupts to the surface‚ or it can refer to the landform created by the solidified lava and fragmental volcanic debris that accumulate near the vent. One could say‚ for example‚ that large lava flows are erupted from Kilauea Volcano in Hawaii‚ the word volcano here signifying a vent. By contrast‚ one could say that Kilauea is a gently sloping volcano of modest size as Hawaiian volcanoes

several factors. The impact of eruptions also depends on physical factors such as viscosity and gaseous content of magma‚ whether eruptions are effusive or explosive‚ the nature of the material erupted e.g. pyroclastic flows‚ superheated gases‚ ash‚ lava etc. There are also human factors such as prediction‚ hazard mitigation‚ and evacuation procedures‚ population distribution and density. Nevado Del Ruiz is an example of a volcanic eruption that was on a large scale with a big impact. The eruption

Hephaestus didn’t realize that his anger had vented down to earth‚ mountains were exploding and pouring out lava‚ thankfully out of range of causing any harm. He had created the first volcano. Regardless‚ Zeus was furious‚ he ordered Hephaestus to clean up the disaster. Hephaestus had no choice but to listen‚ unless he wanted to face Zeus’s wrath. The fire was

liquid-like. The surface is like this‚ because it is searching for any possible escape route to relieve some of the atmospheric pressure. Also‚ with the surface as liquid-like as it is‚ its surface is constantly refilling all impact craters with molten lava. This lava ’s contents are not exactly discovered yet‚ but scientists are led to the belief that it contains sulfur

These craters range in size up to many hundreds of kilometers‚ but the most enormous craters have been flooded by lava‚ and only parts of the outline are visible. The total area of the moon is 37 930 000 square kilometers. One of these craters found‚ is the Alfrancus C. It has a maximum diameter of 10 km and a maximum radius of 5km.

mantle is hotter than average causing ‘mantle plumes’ to rise to the bottom of the lithosphere‚ find a thin or weak part of the lithosphere‚ and breaks through. In the case of the Hawaiian islands‚ the hotspot is underneath an oceanic plate and the lava has built up until it is higher than the surface of the sea. These hotspots remain in the same place in relation to the mantle‚ but the plates move across the hotspots. The Pacific plate has moved across a hotspot in the ocean leaving the chain of
