Volcanoes
The word Volcano comes from "Vulcan", the Roman God of fire.
Volcanos develop where the Earth's crust is weakest, and
they spew molten rock. The molten rock is called magma
underground and lava on the surface. While lava can reach
1200°C, the most dangerous elements of an eruption are ash
and sulfur dioxide gas, which can lead to acid rain.
Volcanos come in many forms including fissure vents,
domes, stratovolcanoes, and supervolcanos, such as
Novarupta, Its eruption was the most powerful eruption
in modern history and could be heard from many 100s of
miles away. The largest volcano in our solar system is
Olympus Mons, on planet Mars, and while Earth might not
have the largest volcano, it does have the one with the
craziest name: the icelandic volcano named
Eyjafjallajökull ("eh-ya-fyat-la-yoo-gut").
