ES 1010‚ Unit 8 Question 11 - Discuss stellar evolution (describing each stage in brief). What forces are opposing one another throughout the life of a star and how do they influence the various stages in the life cycle of a star Stellar evolution stars exist because of gravity. The two opposing forces in a star are gravity (contracts) and thermal nuclear energy (expands). Stage 1 Birth is where gravity contracts the cloud and the temperature rises‚ becoming a protostar. Protostars are a

My Reflection: Honestly I’m not really good in Science. But I’m striving hard to get along with this subject and the same as Math. This subject is one of my weaknesses among all subjects. But now I can get along with this Science subject and luckily I become a lover of this. For me‚ the subject teacher really matters on how I want a certain subject. I really love when it’s Science time and I really enjoy this subject and maybe when you will take a time to open my notebooks‚ my Science notebook

The atmosphere is practically everything above the Earths surface. It starts at ground level and then just goes on upward‚ getting thinner and colder until it finally dissolves into space. The atmosphere makes our world livable. It is responsible for winds‚ weather‚ temperature and a lot more features that make the Earth different than other planets. Without it‚ the Earth would be more like the moon. From a general point of view‚ the atmospheres composition seems simple. It contains oxygen produced
