What is lava?

Answer

Lava is the molten rock that an active volcano emits during an eruption as well as the rock that results when this hot liquid cools and solidifies. Lava is composed of crystals combined with volcanic glass and gases.

"Magma" is the word used for the molten rock deep inside the Earth that becomes lava as it comes to the surface. When the lava first erupts, its temperatures potentially reach as high as 2,000 degrees Fahrenheit. Islands have formed from cooled lava, and lava is often the source of rich soil. Lava's chemical composition is primarily oxygen, silicon, aluminum, iron, calcium, sodium, potassium and magnesium.
