Answer:
1. The nebula shrinks.
2. The temperture increases.
3. The nebula flattens into a disk.
4. The nebula spins.
5. A cloud of Dust and gas forms.
6. Nuclear fusion takes place.
Explanation:
In this exercise you have to arrange the events in the order that they're likely to occur leading up to the formation of the solar system.
For example:
1. The nebula shrinks.
2. The temperture increases.
3. The nebula flattens into a disk.
4. The nebula spins.
5. A cloud of Dust and gas forms.
6. Nuclear fusion takes place.
After that, temperature differences in the nebula cause terrestrial planets to form closer to the center of the nebula and gaseous planets to form farther out. Then, Solar wind from the Sun blows remaining gas into interstellar. space.
