Final answer:
Descriptive communication involves making statements about facts, while evaluative communication expresses judgments and values.
Step-by-step explanation:
Descriptive communication involves making statements about matters of fact and describing how the world is. It focuses on providing objective information without any evaluation or judgment. For example, saying, 'The weather today is sunny' is a descriptive communication because it describes an observable fact.
Evaluative communication, on the other hand, involves expressing a judgment about something's value and how the world ought to be. It is subjective and based on personal beliefs and opinions.
For instance, stating, 'We should protect the environment for future generations' is an evaluative communication as it expresses a value and suggests a course of action.
The main difference between descriptive and evaluative communication lies in the type of claims they make and the nature of the information they convey. Descriptive communication provides factual information about the world, while evaluative communication expresses judgments and values.
