80% of the Earth’s surface is composed by volcanic material

Gaseous emissions from volcanic vents over hundreds of millions of years formed the Earth's earliest oceans and atmosphere, which supplied the ingredients vital to evolve and sustain life. Over time, volcanic eruptions and related processes have directly and indirectly benefited humanity: Volcanic materials ultimately break down and weather to form some of the most fertile soils on Earth, which has produced abundant food and fostered civilizations.
