Exam- 1st Essay and Bib




a) The sun and solar activities take many different patterns in their movement around places. Things like sunspot cycles solar flares, and solar winds mainly take these patterns. These patterns occur because of the magnetic fields in which they lay on. The suns main magnetic area is in the convection zone. This is why they have to move in patterns. The way that they move is the main patterns that occur in this.
b) Things in which occur on the sun also can relate to phenomena such as auroras, distribution of radio and satellite communications, and power grid disturbances. An aurora is similar to the magnetic fields on the sun and the magnetic activity on the sun. “An aurora is sometimes even called the northern and southern lights.”(1) They are natural lights displayed in the sky. The sun is also a natural light in the sky. The sun keeps our sky light during the day. Then sometimes at night you can look up into the sky and it is lit up by the auroras. This is similar and helps for humans like us to be able to see into the sky. The distribution of radio and satellite communications also relates to the sun. This is because it is the main transport of communication. The sun is the main source of light. These are very similar.
c) Nuclear fusion has lead to the formation of all other chemical elements. Its main formation was 2He4. This is the heavier nuclei. It helped to form this and continued as a chain reaction. Also an example of nuclear fusion leading to the formation of another thing is the Big Bang theory. This states that it is believed that fusion was used to help form the universe. This would have to be in continuation of a chain reaction and is a good thing because without the formation of the universe we would not have anywhere to live today. A lot of the time Hydrogen burning is used as nuclear fusion to create a new element as well. This is a great process.
That is my essay about the Sun. The sun is related to many other things that occur in the universe. As well as the sun helps to create other things due to fusion. Without the sun everyone on earth may be dead. I am thankful for the earth today because it creates light for the world, and helps in the formation of many other things.
