Prime Meridian
What is the rule for determining Polaris's altitude?
Polaris's altitude is equal to the latitude of the observer.
Define Rotation.
Earth spinning on its axis.
When both variables increase together.
The stream velocity and particle diameter chart on ESRT p.6 is an example of this!
Direct Relationship
What is the highest latitude you can travel North?
North Pole (90 degrees North)
What is 180 degrees longitude?
International Dateline
What is the altitude of Polaris in Buffalo, NY? (Use ESRT p.3)

15 degrees per hour.
When one variable increases and the other decreases.
Indirect (Inverse) Relationship
What direction do latitude lines run?
Horizontal - they run east to west, but measure north and south.
What direction do longitude lines run?
Vertically. The run north to south, but measure east and west.
At what altitude can an observer at 44 degrees North see Polaris?
44 degrees
If it is 8 am in the EASTERN time zone, what time is it in the MOUNTAIN time zone?
6 am
When one variable increases and the other continues in a predictable pattern.
Ocean tides are a great example.
Cyclic Relationship

Approximately 20 degrees North.
What is the longitude of the Canary Islands Hot Spot? (Use ESRT p.5)
18 degrees West
If an observer views Polaris 66.5 degrees above the horizon, at what latitude is that observer?

What is the longitude of Massena, NY?
At what altitude can observer at 47 degrees South view Polaris?
They cannot. You cannot see Polaris in the Southern Hemisphere.
Your friend lives at 120 degrees West and you live at 75 degrees west. If your friend will be home at 7pm (there time), what time will it be at your house when you call?
