Step-by-step explanation:
1. Describe the earth's early atmosphere and how oxygen was developed in the atmosphere.
When Earth formed 4.6 billion years ago from a hot mix of gases and solids, it had almost no atmosphere. The surface was molten. As Earth cooled, an atmosphere formed mainly from gases spewed from volcanoes. It included hydrogen sulfide, methane, and ten to 200 times as much carbon dioxide as today's atmosphere.
2. Explain the theory of the development of the earth's atmosphere and how oceans were formed.
Many scientists believe that water was present when the Earth was formed. Then the process of outgassing water molecules into the atmosphere, which then rained onto the surface of the Earth as the atmosphere cooled, created the ocean
3. Explain why the compositions of the earth's atmosphere has not changed much for 200 million years.
The atmosphere has stabilized over time as ecosystems have saturated with life.
The atmosphere has stabilized over time as ecosystems have saturated with life.The oceans have stabilized since then as well, as the oceans and atmosphere have strong interactions.
The atmosphere has stabilized over time as ecosystems have saturated with life.The oceans have stabilized since then as well, as the oceans and atmosphere have strong interactions.Life is the source of free oxygen. For the atmosphere to change from where it is now there must be a significant change in the amount of photosynthetic organisms, which changes depend mostly on temperature.

For the atmosphere to change from where it is now there must be a significant change in the amount of photosynthetic organisms, which changes depend mostly on temperature.If there is a major change in temperature such as a new ice age then you might see a significant change in the Earth’s atmosphere
please make me brainalist and keep smiling dude I hope you will be satisfied with my answer
