Bоnus: Wоrth up tо 5 points (ignore thаt it sаys 0 аs I will manually grade submissions). We are so lucky to be alive during our Sun's current stage of evolution. In this bonus essay, choose one future stage of evolution the Sun will go through, and describe two distinct changes either the Earth or Sun will experience during this very different time. Focus your submission on just one stage the Sun will go through at some point later in its life. See rubric below. Please use the ordered and unordered list icon to structure your response in either a numbered or bulleted list to assist me in grading. Rubric: Future Stage: (1 point) This must be a stage the Sun will actually experience or you will not receive credit for the entire submission. First attribute of this stage (2 points) Must pertain to above stage and be clearly explained and supported using lecture content in a minimum of one complete sentence. Second attribute of this stage (2 points) Must pertain to above stage and be clearly explained and supported using lecture content in a minimum of one complete sentence. AI use in writing your answer to this prompt is prohibited and will result in a 0 on the entire exam and will be reported to Student Code of Conduct. No credit will be given for incorrect evolutionary stage or answers without the supporting explanation. Do not discuss more than one stage, provide vague or general answers that could pertain to any stage, or discuss more than 2 unique changes during said stage. For example (not correct): Future stage: typhoon In the future typhoon stage of the Sun, super stellar winds will make space travel much easier as they will get a natural propulsion. During this stage, the Sun will become very puffy and squishy in appearance from Earth.
