Our sun was formed
when the universe began
after many generations of stars had formed and then exploded
when stars first formed in the early universe
6000 years ago
5. the atoms that form in the cores of stars find their way into the ground, the atmosphere and living creatures on earth because of
black holes
the big bang
supernovas
nuclear fusion

6. we’ve mentioned that molecules frequently break apart and form new molecules. discuss at least five common processes where this happens.
7. we’ve seen that while the earth and the sun are composed of the same elements, the proportion that a given element makes up of the earth is generally strikingly different from the proportion of the sun it constitutes. what about other planets? are their chemical compositions more like the earth, more like the sun, or something entirely different?

8. do you think that there are living things on other planets? are there intelligent beings out there?

9. list three new things you have learned after watching this video:
