Abundance of the chemical elements of the volatile elements hydrogen, helium, neon, and nitrogen, as well as carbon which has been lost as volatile hydrocarbons. The remaining elemental composition is roughly typical of the "rocky" inner planets, which formed in the thermal zone where solar heat drove volatile compounds into space. The Earth retains oxygen as the second-largest component of its mass (and largest atomic-fraction), mainly from this element being retained in silicate minerals which have a very high melting point and low vapor pressure. The mass-abundance of the nine most abundant elements in the Earth's crust is approximately: oxygen 46%, silicon 28%, aluminum 8.2%,
The Lowest of the Low Ron Hawkins and the Rusty Nails. In 2000, The Lowest of the Low reunited for a five-show tour, playing to sold-out venues in Toronto and Buffalo. In 2001, the live album "Nothing Short of a Bullet" was released. The album also featured a second disc with three new studio songs, including a cover of the Bad Religion song "Kerosene". In 2002, bassist John Arnott left the band and was replaced by Dylan Parker. "Sordid Fiction", the band's first new studio album since 1994, was released in 2004. Following the tour for that record, the band went on extended hiatus again.
