What does the term "depth" suggest when used to describe an impression?

When the term "depth" is used to describe an impression, it signifies an intense or profound impact. It suggests that the impression affects the observer on a deeper, more meaningful level rather than being superficial or fleeting. A deep impression often evokes strong emotions or thoughtful reflection, indicating a significant or lasting influence that resonates with the individual. This contrasts with interpretations of shallow or trivial reactions, which do not linger or provoke substantial consideration. Thus, the idea of "depth" in this context embodies the richness of experience and the weight it carries, reinforcing its position as the correct answer.
