A.)meteorite bombardment

B.)eukaryotes evolve

C.)oceans form

D.)banded iron formations created

E.)volcanic outgassing

F.)oxygen increases in the atmosphere

G.)cyanobacteria evolve

Verified Answer :

the Sequence of events for the evolution of the atmosphere in the correct order would be :
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.
