Do volcanoes erupt without warning?
The resulting steam-driven eruption, also called a hydrothermal or phreatic eruption, can happen suddenly and with little to no warning. The expansion of water into steam is supersonic in speed and the liquid can expand to 1,700 times its original volume. This produces catastrophic impacts….
How does a volcano react?
Deep within the Earth it is so hot that some rocks slowly melt and become a thick flowing substance called magma. Since it is lighter than the solid rock around it, magma rises and collects in magma chambers. Eventually, some of the magma pushes through vents and fissures to the Earth’s surface.
Is star hotter than Sun?
The sun’s surface temperature is about 5,800° Kelvin (about 10,000° Fahrenheit), and Betelgeuse is roughly half that, about 3,000° Kelvin (about 5,000° Fahrenheit). That is why it is red — red stars are cooler than the sun, blue-white stars are hotter. Betelgeuse is, however, much bigger and brighter.
What type of reaction is a volcanic eruption?
A real volcano eruption is a physical reaction. A physical reaction is a change in the physical properties, rather than the chemical composition, of a substance.

Would dying in lava be painful?
Even in liquid form, most lavas (essentially liquid rock) is more dense and heavier per cubic measure than your body. You’d sink to your ankles or knees depending on its consistency, then fall over and roast to death, briefly but still very painfully until your nerves burnt away.
What triggers volcanoes to erupt?
Although there are several factors triggering a volcanic eruption, three predominate: the buoyancy of the magma, the pressure from the exsolved gases in the magma and the injection of a new batch of magma into an already filled magma chamber. What follows is a brief description of these processes….
What are the similarities and differences between magma and lava?
Magma is composed of molten rock and is stored in the Earth’s crust. Lava is magma that reaches the surface of our planet through a volcano vent.

Can 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!
Which is hotter blue flame or yellow flame?
At hotter temperatures, the flame color moves into the blue-violet end of the visible spectrum.” “Blue flames burn hotter than orange flames, with temperatures reaching up to 3,000 degrees Fahrenheit.” So, blue fire is hotter than yellow or orange fire.
What is blue lava?
