"Thereby" is typically followed by a verb phrase, indicating the action through which the result is achieved. "Therefore" is usually followed by a comma and completes a thought, providing the logical result of the previous statement.

An example of "thereby" is: "He studied hard, thereby passing the exam." Here, it connects the action of studying to the result of passing. An example of "therefore" is: "It was raining, therefore the event was canceled," where it connects the condition of rain to the conclusion of canceling the event.
