What is the source of materials for volcanoes that erupt in both ways How do you know?
On Earth, the erupted material can be liquid rock (“lava” when it’s on the surface, “magma” when it’s underground), ash, cinders, and/or gas. There are three reasons why magma might rise and cause eruptions onto Earth’s surface. Volcanoes on Earth form from rising magma. Magma rises in three different ways.
What is the source material for volcanic eruptions?
Since volcanic eruptions are caused by magma (a mixture of liquid rock, crystals, and dissolved gas) expelled onto the Earth’s surface, we must first discuss the characteristics of magma and how magmas form in the Earth. Types of magma are determined by chemical composition of the magma.
What are two ways volcanoes can erupt?
There are two types of eruptions in terms of activity, explosive eruptions and effusive eruptions. Explosive eruptions are characterized by gas-driven explosions that propels magma and tephra.
What is the most dangerous type of eruption?
Composite volcanoes are some of the most dangerous volcanoes on the planet. They tend to occur along oceanic-to-oceanic or oceanic-to-continental boundaries because of subduction zones.
Which volcano will destroy the world?
Yellowstone supervolcano

What is the most deadliest volcano in the world?
Vesuvius volcano
What volcano killed the most?
Mount Tambora
What is the hottest volcano on Earth?

How does volcano kill you?
Most people killed by volcanoes are the victims of pyroclastic flows and lahars – volcanic mudflows, packed with debris – which have been responsible for about 120,000 deaths over the last 500 years. Pyroclastic flows are very fast avalanches of rock, ash and gas, which can reach temperatures of 700C.
Can you walk in lava?
As long as you can bear the heat, it means lava is strong enough for you to walk on it. If your shoes start taking fire, just move away!
Would dying in lava be painful?
It isn’t really an either/or question. You might burst into flames and burn when you hit the lava/magma’s surface (depending on the type, lava’s temperature ranges from approximately 1,200 to 2,200 degrees). You might also burn before you hit the lava/magma due to the radiant heat.
Can lava melt bones?
High enough heat will indeed burn bone. Anything living that has bones would certainly be destroyed by lava.
Can you drink lava?
Lava, or magma that is on the surface of the earth, is around 1,125 degrees. If you tried to eat it, you would suffer burns before you ever got it in your mouth. You wouldn’t be able to swallow it — lava is molten rock, and as such, is extraordinarily dense and viscous.
What is blue lava?
Indonesia’s Kawah Ijen volcano spews out blue lava thanks to its incredibly high levels of sulfur. It is one of the world’s most unusual volcanoes because instead of producing the usual red lava and black smoke, its underground activities result in bright blue flames rising into the air.
How fast would lava kill you?
Death comes a few minutes later. However, there are different types of lava, and with the cooler ones, one might actually hope to survive, just like a Masaai tribesman did[4] . I wouldn’t bet my money on it, though. In conclusion, it might take anywhere from immediately to 10 minutes to die, depending on circumstances.
Do you die instantly if you fall in lava?
Most lava is very hot—about 2,000 degrees Fahrenheit. At those temperatures, a human would probably burst into flames and either get extremely serious burns or die. Unlike a lake, people won’t immediately sink into lava.
Is lava hotter than fire?
While lava can be as hot as 2200 F, some flames can be much hotter, such as 3600 F or more, while a candle flame can be as low as 1800 F. Lava is hotter than a typical wood or coal-buring fire, but some flames, such as that of an acetylene torch, is hotter than lava. Red lava is colder than candle flames.
Can lava melt diamonds?
According to Wikipedia, the temperature of lava is between 700 and 1200 °C (973 to 1473 K). The melting point of Diamond at about 100,000 atm is 4200 K, which is much higher than the temperature of lava. So, it is impossible for lava to melt a diamond.
Does anything live in lava?
Yes, it’s quite possible for living organisms to live in cool, solidified lava. We see that all over the place on the Big Island. Molten lava on the otherhand is far too hot for anything to live in it. Generally it is not possible but some bacteria are able to live in larva also…
What can destroy a diamond?
Steel and other rocks can be used to easily crush a diamond. Like I said earlier, super heating a diamond can set it on fire, and even throwing diamonds into your furnace will burn them all up.
