Latitude is the angular distance north or south of the Equator, measured in degrees. Lines of latitude (parallels) run east-west around the globe. The Equator is at 0° latitude. The North Pole is at 90°N, the South Pole at 90°S. What is the latitude of the Equator?

Longitude is the angular distance east or west of the Prime Meridian, measured in degrees. Lines of longitude (meridians) run north-south and converge at the poles. The Prime Meridian (0° longitude) passes through Greenwich, London, England. The International Date Line is at 180° longitude. What is the longitude of the Prime Meridian?

The Equator is the line of latitude at 0°. It is the longest line of latitude (about 24,901 miles / 40,075 kilometers). The Equator divides the Earth into the Northern and Southern Hemispheres. Countries that lie on the Equator include Ecuador (named after the Equator), Colombia, Brazil, Kenya, Somalia, Indonesia, and others. Which ocean does the Equator NOT pass through?

The Tropic of Cancer is at 23.5°N latitude. The Tropic of Capricorn is at 23.5°S latitude. These lines mark the northernmost and southernmost points where the sun can be directly overhead. The area between these two lines is called the tropics. The sun is directly overhead at the Tropic of Cancer on the June solstice (about June 21). Which line of latitude is at 23.5°N?

The Prime Meridian (0° longitude) passes through Greenwich, London, England. It is the reference point for time zones (Greenwich Mean Time, GMT). The Royal Observatory in Greenwich marks the location of the Prime Meridian. Visitors can stand with one foot in the Eastern Hemisphere and one foot in the Western Hemisphere. Which city is the Prime Meridian located in?

The International Date Line (IDL) is an imaginary line at approximately 180° longitude. When you cross the IDL going west, you add a day; crossing east, you subtract a day. The IDL is not a straight line; it deviates to avoid splitting countries and island groups. What happens when you cross the International Date Line going west?

The Arctic Circle is at 66.5°N latitude. The Antarctic Circle is at 66.5°S latitude. Within these circles, there is at least one day of 24-hour daylight (midnight sun) and one day of 24-hour darkness (polar night). Which country has land within the Arctic Circle?

Coordinates are given as (latitude, longitude). Latitude is always given first. Example: The coordinates of the Statue of Liberty are approximately 40.7°N, 74.0°W. Which continent is located at 30°N, 30°E? (Hint: 30°N is about the latitude of Egypt; 30°E is about the longitude of Egypt.)

Time zones are based on longitude. The Earth rotates 360° in 24 hours, so each 15° of longitude corresponds to 1 hour of time difference. There are 24 time zones (one for each hour). Greenwich Mean Time (GMT) is the reference. Eastern Standard Time (EST) is UTC-5 (5 hours behind GMT). How many degrees of longitude correspond to 1 hour of time difference?

The Equator divides the Earth into the Northern and Southern Hemispheres. The Prime Meridian and the International Date Line divide the Earth into the Eastern and Western Hemispheres. The United States is located in which hemispheres?
