Final answer:
Nonverbal communication consists of facial expressions, hand gestures, and posture, revealing emotions and intentions beyond spoken language.
Step-by-step explanation:
Examples of nonverbal communication include facial expressions, hand gestures, and posture. These elements of body language serve as an essential part of interpersonal communication, often conveying more than spoken words alone. For instance, a smile typically suggests happiness or friendliness, and a thumbs-up gesture may signify approval in certain cultures but can be offensive in others like Russia and Australia. Facial expressions and body movements can often reveal a person's emotions even in the absence of words, such as furrowed brows and folded arms hinting at a serious conversation or possibly an argument, while smiles with heads lifted and arms open could indicate a light-hearted, friendly exchange.
