What is magma and how does it differ from lava? When geologists refer to magma, they’re talking about molten rock that’s still trapped underground. If this molten rock makes it to the surface and keeps flowing like a liquid, it’s called lava. Magmas vary in their chemical composition, which gives them—and the volcanoes that contain them—different properties.

Is the temperature of lava increases?
Lavas range in temperature from about 800 °C (1,470 °F) to 1,200 °C (2,190 °F). This is similar to the hottest temperatures achievable with a forced air charcoal forge. A lava is most fluid when first erupted, becoming much more viscous as its temperature drops.
