How are volcanos formed?
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 this happens, the ocean plate sinks into the mantle.
How are volcanoes formed by plate tectonics?
Plates rip apart at a divergent plate boundary, causing volcanic activity and shallow earthquakes; and. At a convergent plate boundary, one plate dives or “subducts” beneath the other, resulting in a variety of earthquakes and a line of volcanoes on the overriding plate.
What type of volcano is Kilauea?
Kīlauea Volcano is a shield volcano located on the eastern slope of Mauna Loa Volcano on the Island of Hawai’i. The volcano is considered to be in the shield-building stage of Hawaiian volcanism.
How was the Kilauea volcano formed?
Like all Hawaiian volcanoes, Kīlauea was created as the Pacific tectonic plate moved over the Hawaiian hotspot in the Earth’s underlying mantle. The Hawaii island volcanoes are the most recent evidence of this process that, over 70 million years, has created the 6,000 km (3,700 mi)-long Hawaiian–Emperor seamount chain.

Can lava melt your bones?
In addition to the “bones don’t melt” answers which can be supplemented with “meat does not melt”, it is interesting to note what happens on the rare occasions that people have fallen into lava. The lava is very close to its freezing point as it oozes across the ground- it is basically just barely molten.
Can lava melt diamonds?
To put it simply, a diamond cannot melt in lava, because the melting point of a diamond is around 4500 °C (at a pressure of 100 kilobars) and lava can only be as hot as about 1200 °C.

Is Mount Everest a volcano?

Which body part does not burn in fire?
Quite often the peripheral bones of the hands and feet will not be burned to such a high intensity as those at the centre of the body, where most fat is located.
What happens if you touch lava?
Lava won’t kill you if it briefly touches you. You would get a nasty burn, but unless you fell in and couldn’t get out, you wouldn’t die. With prolonged contact, the amount of lava “coverage” and the length of time it was in contact with your skin would be important factors in how severe your injuries would be!
Can the sun melt a diamond?
However, you needn’t worry about leaving a diamond in the sun. It would take a temperature of 700-900°C before it started to burn, since the carbon atoms in a diamond are in a tight three-dimensional array that’s very hard to disrupt.
