Lava is made up of crystals, volcanic glass, and bubbles (volcanic gases). As magma gets closer to the surface and cools, it begins to crystallize minerals like olivine and form bubbles of volcanic gases.When lava erupts it is made up of a slush of crystals, liquid, and bubbles.The liquid freezes to form volcanic glass. Chemically lava is made of the elements silicon, oxygen, aluminum, iron, magnesium, calcium, sodium, potassium, phosphorus, and titanium (plus other elements in very small concentrations.Have a look at the background information in Minerals, Magma, and Volcanic Rocks.he liquid freezes to form volcanic glass.

Lava is molten rock. It is formed inside the Earth and is liquefied by a source of heat called geothermal energy. Lava is made up of igneous rocks. CaitlynnReeves | Student, Grade 12 | TA | (Level 1) Salutatorian. Posted on. (Answer #2). Lava is molten rock that has been crushed and heated in the earth's mantle.Answer #1). Lava is formed from âmagmaâ, which is nothing but a very hot liquid (fluid or semi-fluid) that flows inside the Earth. When a volcano erupts, this magma comes out and reaches the Earth surface, cools down after contact with the atmosphere and finally becomes lava.
