Volcanos are releasing ash and smoke into the environment on 3 continents. That may well be earning you assume back to your elementary faculty science course when you likely researched volcanoes and lava.
Lava is the sort of magma, or molten or semi-molten rock, that erupts to the surface, these types of as by using a volcano or via a crust fracture.
We all know lava is pretty very hot, but particularly how very hot is lava? This is what to know about the molten rock’s temperatures.
How very hot is lava?
Lava’s temperature can assortment among 1,300 to 2,200 degrees Fahrenheit.
For illustration, lava touring through a Hawaiian volcano’s tubes, or underground passageways, is about 2,200 levels Fahrenheit, in accordance to the United States Geological Survey.
Furthermore, depending on rock variety, lava’s temperature ranges. According to Oregon Condition College, these are the temperatures of common lava kinds:
- Rhyolitic lava: 1292 to 1652 levels Fahrenheit
- Dacite lava: 1472 to 2012 levels Fahrenheit
- Andesite lava: 1742 to 2192 levels Fahrenheit
- Basalt lava: 1832 to 2282 degrees Fahrenheit

What is lava created of?
Lava is designed of crystals, volcanic glass and bubbles (also regarded as volcanic gases), according to Oregon Condition College.
Lava forms when magma erupts. When magma becomes too a lot to take care of, gases will not be in a position to exit the landform. This qualified prospects force to establish up and will at some point cause an explosion of fuel and lava, according to the USGS.
As for its chemical makeup, lava has silicon, oxygen, aluminum, iron, magnesium, calcium, sodium, potassium, phosphorus and titanium, as effectively as tiny amounts of other aspects.

What is magma?
Magma is extremely sizzling molten or semi-molten rock located underneath the Earth’s surface, according to National Geographic. A the vast majority of Earth’s magma is discovered in the mantle, or layer among the core and crust.
When magma erupts or flows from the Earth, it is then termed lava.
There are three types of magma, according to National Geographic:
Every variety has its personal mineral composition, but magma is also designed of “smaller amounts of dissolved gases such as water vapor, carbon dioxide, and sulfur,” in accordance to Countrywide Geographic.
Can you touch lava?
You really should not contact lava. If your skin will come in contact with lava, you would get severely burned.
When you make get in touch with with temperatures, the severity of your injuries relies upon on how prolonged you touch it and how sizzling it is.
According to the Countrywide Institute for Requirements and Technological know-how, you will commence to feel pain at a temperature of 111 degrees Fahrenheit. You would maintain to start with-diploma burns at a temperature of 118 degrees. At a temperature of 162 levels, your pores and skin tissue would be “quickly destroyed.”
