00:00:34
learn more about it a volcano is a vent or chimney that connects magma from within the earth's crust
00:00:43
the Earth's surface. The liquid rock is called magma when it is under the Earth's
00:00:52
surface and lava after it comes out. So how does a volcano erupt? The molten rock
00:00:58
stored in the magma chamber rises through the crater pipe pockets. As it
00:01:11
travels up the main vent gases expand and water becomes steam creating pressure when the pressure
00:01:16
can no longer be contained the volcano erupts through the crater and secondary side vents
00:01:24
common volcanic gases include water vapor carbon dioxide sulfur dioxide hydrogen chloride hydrogen
00:01:31
fluoride and hydrogen sulfide popular belief is that volcanoes are large
00:01:41
cone-shaped mountains but that's not true there are many more types of
00:01:47
volcanoes such as white plateaus fissure vents and bulging dome shapes there are
00:01:53
also volcanoes found on the ocean floor and even under ice caps such as those
00:02:01
found in Iceland trivia time the word volcano originally comes from the name
00:02:08
of the Roman god of fire Vulcan the tallest volcano in the solar system
