Can you distinguish between lava & magma?

Scientists use the term magma for molten rock that is underground and lava for molten rock that breaks through the Earth’s surface.

What is the largest difference between magma and lava?

The main difference between magma and lava is that when this molten rock is within the Earth, it is known as magma but when magma reaches the surface and erupts from a volcano, it becomes lava.

What is difference between volcano and lava?

is that volcano is a vent or fissure on the surface of a planet (usually in a mountainous form) with a magma chamber attached to the mantle of a planet or moon, periodically erupting forth lava and volcanic gases onto the surface while lava is the melted rock ejected by a volcano from its crater or fissured sides.

Why do magma and lava have different names?

Magma comes from an Italian word that means a thick, pasty substance, which is how molten rock behaves within the Earth. Lava, another Italian word, means to slide, which is what molten rock does once it reaches the surface. All magma contains dissolved gases. …

Which is hotter magma or lava?

Lava is hotter than magma. Lava’s temperature usually ranges between 1300 and 2200 degrees F. The temperature of magma usually ranges between 1300 and 2400 F. Lava cools much faster than magma, which may lead to part of the melt being unable to crystallize and thus becoming glass.

Is magma a lava?

Magma is extremely hot liquid and semi-liquid rock located under Earth’s surface. When magma flows or erupts onto Earth’s surface, it is called lava. Like solid rock, magma is a mixture of minerals.

Whats hotter fire or lava?

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.

What would happen 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!
