What are 10 facts about volcanoes?
Check out these 10 facts about volcanoes…
- Volcanoes are openings of the Earth’s surface.
- The word volcano comes from the word ‘vulcan’.
- Volcanoes can be active, dormant or extinct.
- The liquid inside the volcano is called magma.
- Lava is the liquid that is expelled from the volcano.
- Lava is very, very hot!
What type of volcano is Aoba?
Ambae (Aoba) is a large basaltic shield volcano in the New Hebrides arc, part of the multi-island country of Vanuatu. Its periodic phreatic and pyroclastic explosions originating in the summit crater lakes have been recorded since the 16th century.

What type of volcano starts with AC?
Cinder cones are the simplest type of volcano. They are built from particles and blobs of congealed lava ejected from a single vent.
How fast do volcanoes grow?
How Long Does it Take a Volcano to Grow? Volcanoes are created over approximately 10,000-500,000 years by thousands of eruptions — each lava flow covering the one before it. In the case of oceanic island volcanoes, lava erupts first from fissures, or cracks, on the deep ocean floor.
What are the 3 types of volcanoes?
There are three types of volcanoes: cinder cones (also called spatter cones), composite volcanoes (also called stratovolcanoes), and shield volcanoes. Figure 11.22 illustrates the size and shape differences amongst these volcanoes. Shield volcanoes, which get their name from their broad rounded shape, are the largest.

Are volcanoes male or female?
In psychological terms, both genders are represented within a volcano: a mountain that ejects materials may represent a phallis while a caldera may represent a womb, the cradle of the generative force.
How hot is lava?
The temperature of lava flow is usually about 700° to 1,250° Celsius, which is 2,000° Fahrenheit. Deep inside the earth, usually at about 150 kilometers, the temperature is hot enough that some small part of the rocks begins to melt.
How hot is a volcano?
When a volcano erupts, the surroundings can get pretty warm. Basalt lava (the most common type) can reach temperatures of around 1200 degrees Celsius, while rocks scattered around the volcano can also reach temperatures of up to 1,000 degrees Celsius.
How did volcanoes start?
On land, volcanoes form when one tectonic plate moves under another. Usually a thin, heavy oceanic plate subducts, or moves under, a thicker continental plate. When enough magma builds up in the magma chamber, it forces its way up to the surface and erupts, often causing volcanic eruptions.
Where are most volcanoes located?
Pacific Ocean
Sixty percent of all active volcanoes occur at the boundaries between tectonic plates. Most volcanoes are found along a belt, called the “Ring of Fire” that encircles the Pacific Ocean. Some volcanoes, like those that form the Hawaiian Islands, occur in the interior of plates at areas called “hot spots.”
Do you know these amazing volcano facts?
Prepare to delve into the depths of the earth and uncover these seriously hot volcano facts – if you dare! 1. Put simply, a volcano is an opening in the Earth’s surface. Usually found in a mountain, the opening allows gas, hot magma and ash to escape from beneath the Earth’s crust.
How many people live in the shadow of a volcano?
About 20% of all volcanoes are underwater. [1] More than 300 million people (nearly 1 in 20) live in the shadow of active volcanoes, including Mount Vesuvius in Italy, Mount Rainier in the U.S., and Popocatepetl in Mexico. [16]
How many people live near active volcanoes?
Approximately 350 million people live within “danger range” of an active volcano. That means that around one in 20 people live in an area at risk of volcanic activity.
What are 64 explosive facts about volcanoes?
64 Explosive Facts about Volcanoes. New ocean floor is created when two oceanic plates move apart and magma bubbles up to fill the rift. This is called a rift volcano. Through this process, the Atlantic Ocean is widening by 2 cm. per year, and the East Pacific Rise is widening by 20 cm. a year.
