Final answer:
Ethos is an appeal to credibility, while ethics refers to principles of conduct. Ethos focuses on the credibility of the speaker, while ethics is concerned with moral principles.
Step-by-step explanation:
Ethos is an appeal to ethics, establishing the writer's or speaker's credibility. It often invokes the speaker's character and qualifications on the subject. On the other hand, ethics refers to principles of right and wrong conduct. Ethos focuses on the credibility of the speaker, while ethics is concerned with moral principles.
For example, in a persuasive speech about climate change, a speaker can establish ethos by mentioning their expertise in environmental science or their involvement in related research. Ethics, on the other hand, would explore the moral implications of addressing climate change and the responsibilities individuals have to protect the environment.
