Volcanoes
Composite Volcano
The composite volcano, also known as the Stratovolcano, the lava that is dispensed by composite is thick and sticky, a goes down a steep slope. Before erupting, the gas inside the volcano cannot escape because the lava is blocking it, so when the pressure reaches a high enough level, it will erupt in a explosive manner, and lava and ash will spew out of the funnel. They have a tall and thin shape. Examples of composite volcanos are Mt. Vesuvius. In AD 79, it erupted in a massive explosion of lava and ash, burying two cities, Pompeii and Herculaneum. It is now dormant unlike Tavurvur, which is active and erupted in 2013. |
Cinder Cones
Cinder cone volcanoes are circular and cones built by lava falling, cooling and then forming cinders around the vent. Examples of Cinder cones are Ibex mountain, in Yukon, Mount Wellington in New Zealand. But also where there are shield volcanoes, there are cinder cones. There are over 100 cinder cones near Mauna Kea in Hawaii. |
