2. Aim: How do we determine the time at different cities?
Do Now: In your notes, explain why our local time is different in other parts of the world.

If you have the following:
Green review book-read pages solar time and clock time
Answer the following in your notes:
What is Greenwich Mean Time (GMT)?

6. Solar time- the time of day at a specific longitude.
You can find your local time based on the current solar time at Greenwich, England (GMT).
Any location west of the Prime Meridian (GMT or UTC) is behind.
Any location east of the Prime Meridian (GMT or UTC) is ahead.

8. It takes the Earth to rotate once every 24 hours; or 360 degrees.
360 degrees/24 hours=?
Now you try to find the times at different cities.
Lines of longitude are 15 degrees apart.
