Volcanic Eruptions

Describe pyroclastic material and lava

What is Pyroclastic material?

Pyroclastic material is fragments of rock material that form during a volcanic eruption; this comes from felsic lava. It's very light in color and is ejected very violently. Felsic lava has high viscosity and is made up of silica and feldspar. Also, this type has more trapped gases.

Types of Lava :

Types of lava

Mafic magma results as a quiet eruption, therefore it is darker in color and has less trapped gases. This magma is made up of magnesium and iron and is low viscosity. This magma is also classified into three types of lava: Pahoehoe, Aa, Blocky Lava that is what makes up shield volcanoes.
