Arrange the following events in order of the formation of a planetary system.
Answer to Problem 1QP
The following events are arranged in order of the formation of a planetary system.
Explanation of Solution
A planetary system is a system of planets, their moons and other smaller objects in orbit around a star.
Primary atmosphere is composed most of hydrogen and helium.
The same time of forms that host the planet.
Secondary atmosphere is forms as a result of comet impacts, volcanism or another process. Sometimes after this formation its host planet has formed.
Conclusion:
Arrangement in order of formation of a planetary system,
- 1. Gravity collapses a cloud of interstellar gas
- 2. A rotating disk forms
- 3. Dust grains stick together by static electricity
- 4. Small bodies collide to form larger bodies
- 5. Primary atmospheres form
- 6. A stellar wind ‘turns on’ and sweeps away gas and dust
- 7. Primary atmospheres are lost
- 8. Secondary atmospheres form
Therefore, the following events are arranged in order of the formation of a planetary system.
