Roman History Of the Name Volcano
The word volcano comes from a name of a Roman god of fire Vulcan. Vulcan’s story is that Zeus his farther didn’t want him because he was deformed. So he threw him down to earth and he landed in the ocean soon after he was saved and raised by nymphs. Over time he became a famous blacksmith that made Zeus’s thunderbolts, Pandora and other famous things used in Roman history.
Different Types of Volcanoes
There are three different types of volcanoes active, dormant, and extinct. Active volcanoes are the ones who have erupted recently, and they may do so again. Dormant volcanoes are ones with magma in them but have not erupted in a long time but may erupt. Extinct volcanoes are ones who have erupted and who are not going to ever erupt again (no magma in them). There are also volcanoes on other planets in our solar system.
How Volcanoes are Made and what they can do
Volcanoes are normally in locations where tectonics plates meet because there is a gap where the magma can travel up. Volcanoes are created when there is a lot of pressure from magma coming from different directions so then it starts rising and will make a mountain full of magma. Pressure from the magma will make an eruption where magma flows out and ash and rock spit out. An erupting volcano can cause tsunamis, flash floods, earthquakes, mud flows, and rock falls.
Volcanoes and Eruptions over Time
Over time in the past 10,000 years there have only been around 15,000 volcanoes on land that are active. Under water the number of volcanoes is way more then on land but the number is unknown. There are 600 volcanoes during this current period of time. Each year 50-60 volcanoes erupt and over 75% of volcanoes are located around and in the Pacific Ring.
