Lava is made up of volcanic glass, volcanic gases, and crystals. Once the magma arrives near the surface and starts to cool, it crystallizes the minerals and forms volcanic gases.

How are Pillow Lava and Pahoehoe lava the same?

What type of lava is considered intermediate composition?

What is the lava composition of the abu volcano?

Whats the composition of lava for Mt Pelee?
Mount Pelee is an active volcano in the West Indies. Its magma composition is andesitic, having a cone that is composed of layers of hardened lava.
Does mt st Helens have pahoehoe or AA lava?
Niether. Pahoehoe and a'a are both varieties of basaltic lava. The material from Pinatobo is of a dacitic composition, which is much more viscous than a'a or pahoehoe. It tends to erupt explosively, producing ash and pumice rather than lava flows. When dacitic lava does flow it creates a block lava flow.
What is the lava composition for surtsey?
The magma and lava of Surtsey has a composition of alkali Olivine Basalt.
What is the composition of a lava dome?

Lava will cool to form extrusive igneous rock. The exact type would depend on the composition of the lava.

Lava will cool to form extrusive igneous rock. The exact type would depend on the composition of the lava.
What determines the color of a igneous rock?

What 3 factors affect the formation of lava?
Composition, heat, and pressure.
