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 hot molten rock that erupted from volcano Magma is hot material below earths crust, from which lava is formed So the basic difference is just that lava is hot molten r â¦ ock that already erupted; while magma is what is inside earth' s crust. 10 people found this useful.xists and is an alternate of.

Magma and lava are both molten (liquid) rock, but magma is molten rock produced underneath earth's surface and lava is the magma that was produced that is flowing onto earth's surface.
