Final answer:
The term 'depth' in the context of speeches refers to a detailed exploration of a topic beyond common knowledge, providing thorough explanations that answer more questions than they raise.
Step-by-step explanation:
In the context of intellectually stimulating speeches, the term 'depth' involves going into more detail than people's general knowledge of a topic. It emphasizes the importance of providing a layered and nuanced understanding that avoids raising more questions than it answers. This approach helps avoid superficial explanations and instead facilitates a deeper exploration of the subject matter. For example, rather than just stating that John Glenn was an astronaut, a speech with depth might explore his individual experiences, the complexities of space travel, and the impact of his missions on space exploration.
Depth in intellectual discussions and presentations ensures that explanations are thorough and don't leave critical aspects unaddressed. It contrasts with breadth, which might provide a broad overview without delving into specifics, and comparison, which looks at similarities and differences without necessarily exploring the underlying details of a single subject extensively.
