What is a word for magma?

Although lava and magma are often used interchangeably, technically magma is the name for the hot molten rock (mixed with gases and mineral crystals) that collects in chambers beneath the Earth’s crust. Once the magma breaks through the Earth’s surface and flows down the volcano, you can call it lava.

What is magma one word answer?

What is the full meaning of magma?

Magma (from Ancient Greek μάγμα (mágma) ‘thick unguent’) is the molten or semi-molten natural material from which all igneous rocks are formed. Magma is found beneath the surface of the Earth, and evidence of magmatism has also been discovered on other terrestrial planets and some natural satellites.

Is magma molten rock?

Magma is a molten and semi-molten rock mixture found under the surface of the Earth. When magma is ejected by a volcano or other vent, the material is called lava. Magma that has cooled into a solid is called igneous rock. Magma is extremely hot—between 700° and 1,300° Celsius (1,292° and 2,372° Fahrenheit).

lava, magma (molten rock) emerging as a liquid onto Earth’s surface. The term lava is also used for the solidified rock formed by the cooling of a molten lava flow. The temperatures of molten lava range from about 700 to 1,200 °C (1,300 to 2,200 °F).

Why is lava Hot?

Lava is hot for two primary reasons: Pressure and radiogenic heating make it very hot deep in the Earth (about 100 km down) where rocks melt to make magma. The rock around the magma is a good insulator so the magma doesn’t lose much heat on the way to the surface.
