What is the approximate altitude of Polaris at Syracuse, New York

• 76°

• 47°

• 43°

• 90°

The North Star (Polaris) can be used for navigation in Earth's Northern Hemisphere because

• Polaris is located directly over the Tropic of Cancer

• the altitude of Polaris is equal to the observer's latitude

• the position of Polaris changes with the seasons

• Polaris is the brightest and most easily located star

The North Pole is at what degrees of Latitude

• 180* North

• 90* South

• 90* North

• 180* South

The angle of the star Polaris above the northern horizon can be used to determine an observer's

• solar time

• latitude

• longitude

• local time
