Imagine a single dot on a ping pong ball. How would you describe its location?

It would be quite difficult. The same is true of locations on the Earth's surface. Geographers have solved this problem by creating latitude lines and longitude lines.

Latitude defined…

Latitude: (parallels) imaginary lines going from the east to the west (right to left), but dividing the globe north to south. They are called parallels because they never

touch. These lines are measured in degrees.

Equator: an imaginary line that divides the earth into northern and southern hemispheres. It is the zero degrees latitude.

Divides Earth into Sections

Measured in Degrees

Important Latitude Lines

Tropic of Cancer: 23 ½°N north of the equator. The farthest point north at which the sun can shine directly overhead.

Tropic of Capricorn: 23 ½ °S south of the equator. The farthest point south at which the sun can shine directly overhead.

Arctic Circle: 66 ½° N the frigid zone located directly on the center of the north pole.

Antarctic Circle: 66 ½° S the frigid zone located directly on the center of the south

LINES OF LONGITUDE

Longitude Defined

Longitude – also called meridians; imaginary lines that extend from the North Pole to the South Pole

Prime Meridian – 0° longitude line, running though Greenwich, England.

Eastern Hemisphere Western Hemisphere

TIME ZONES

Int’l Date Line

Int’l Date Line Defined

International Date Line – an imaginary line on the Earth’s surface at 180° longitude, mostly through the Pacific Ocean, to the east of which the calendar date is one day earlier than to the west

Since its beginning, the International Date Line has zigzagged to avoid spitting apart countries into two days. It bends through the Bering Strait to avoid placing far northeastern Russia in a different day than the rest of the country.

Key Terms time zone – The method of tracking the 24 hours

throughout the 360 degrees of the earth’s circumference. Each time zone generally equals 15 degrees longitude.

standard time zone – a region in which the same time is used

daylight saving time – a plan in which clocks are set one hour ahead of standard time for a specific time for a specific period of time

More Key Terms

A.M. ante meridiem (Latin) – “before noon”

P.M. post meridiem (Latin) – after noon
