Description
Radioactive elements inside Earth decay and planetesimals bombard Earth and her sister planets, causing tremendous heating. Heavy metals sink to form cores, while volcanoes spew lighter elements into the atmospheres. This "outgassing" transforms the early atmospheres.
The sister planets of the inner solar system – Mercury, Venus, Earth, Mars – reach their current configurations during this phase.
