1. meteorite bombardment
2. Volcanic Outgassing
3. Oceans Form
4. Banded Iron Formations Created
5. cyanobacteria evolve
6. Oxygen increases in atmosphere
7. Eukaryotes evolve
hope this helps

Answer;
Sequence of events;
1. meteorite bombardment
2. Volcanic Outgassing
3. Oceans Form
4. Banded Iron Formations Created
5. cyanobacteria evolve
6. Oxygen increases in atmosphere
7. Eukaryotes evolve
Explanation;
-Scientists believe that the Earth was formed about 4.5 billion years ago. Its early atmosphere was probably formed from the gases given out by volcanoes.
-Evidence related to the evolution of Earth’s atmosphere, though indirect, is abundant. Ancient sediments and rocks record past changes in atmospheric composition due to chemical reactions with Earth’s crust and, in particular, to biochemical processes associated with life.
-Earth’s original atmosphere was rich in methane, ammonia, water vapour, and the noble gas neon, but it lacked free oxygen.
