Two students are talking about what causes the tides. Student A says that the tide comes in and goes out based on differences in the height of the sea level. Student B says that the changing tides are caused by Earth rotating into and out of the tidal bulges. Discuss the explanations of the tides by both Student A and Student B. Which explanation is more technically correct

Student A is more technically correct
