Detailed explanation-2: -When hot, liquid rock (magma) erupts from a volcano onto Earth’s surface it is called lava. If there is pressure inside the volcano, this red-hot, glowing liquid may spurt up into the air like a fountain.

Detailed explanation-3: -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).

Detailed explanation-4: -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.

Detailed explanation-5: -Lava is a liquid, that cools into rock, which is a solid. BACKGROUND: Lava is molten rock (a liquid) that flows on the earth’s surface. Lava is formed inside the crust of the Earth by extreme heat; it erupts to form a volcano.
