In this lesson, you will learn about the particularly important topic of "Latitude, Longitude, and Time Differences" among maps and geographic information. Rather than memorizing words alone, aim to explain the structure and reasons in your own words.
Key Points
Because Earth rotates 360 degrees in 24 hours, a difference of 15 degrees of longitude equals a one-hour time difference, and the time is later farther east.

Points to Remember
- Check not only the conclusion but also the reason for it
- Distinguish similar words and exceptions
- Try using the same way of thinking with other examples
Practice
- Explain the key points in two sentences.
- Give one common misunderstanding and explain what is different about it.
- Check by applying it to a familiar or specific example.
