# Latitude and Longitude - PowerPoint PPT Presentation

Latitude and Longitude. Latitude lines run east/west but they measure north or south of the equator (0 °) splitting the earth into the Northern Hemisphere and Southern Hemisphere. Lines of latitude are numbered from 0 ° at the equator to 90° N.L. at the North Pole.

Latitude lines run east/west but they measure north or south of the equator (0°) splitting the earth into the Northern Hemisphere and Southern Hemisphere.

Lines of latitude are numbered from 0° at the equator to 90° N.L. at the North Pole.

Lines of latitude are numbered from 0° at the equator to 90° S.L. at the South Pole.

The equator is at 0° latitude. It is neither north nor south. It is at the center between north and south.

40° N is the 40° line of latitude north of the equator.

40° S is the 40° line of latitude south of the equator.

LatitudeThe North Pole is at 90° NThe South Pole is at 90° S

60° W is the

60° line of

longitude west

of the Prime

Meridian.

The Prime Meridian is located at 0°. It is neither east or west

60° E is the 60° line of longitude east of the Prime Meridian.

LongitudeLines of longitude begin at the Prime Meridian.

Lines of longitude are numbered east from the Prime Meridian to the 180° line and west from the Prime Meridian to the 180° line.

Places located east of the Prime Meridian have an east longitude (E) address. Places located west of the Prime Meridian have a west longitude (W) address.

A location’s coordinates pinpointed(____° N or S, ____ ° E or W)

Application pinpointedN

North America is in the Northern Hemisphere because it is north of the Equator. North America is in the Western Hemisphere because it is west of the Prime Meridian.

Fractions of a Degree pinpointed

• 1 degree = 60 minutes or 1 minute is 1/60th of a degree

• Use minutes if location is not directly on the latitude/longitude line

• Written ----- Degree/minute = XX° xx’ compass direction

30’ is half-way between degrees

LONGITUDE AND TIME pinpointed

• The world rotates (spins) 360° in 24 hours.

360° / 24 hours = 15° per hour

• The world has 24 time zones, each l5° apart.

THERE IS A 1 HOUR TIME DIFFERENCE FOR EVERY 15° OF LONGITUDE

• The world rotates west to east (counterclockwise), time zones to the east are ahead of the those time zones to the west

• EAST INCREASE

Time is forward to all places to the east

• WEST LESS

Time is backward to all places to the west

East Increase – West Less zones(1 hr per l5°)

If it 9 p.m. at Position D, what time is it at position C? Position B?

If it is 1 p.m. at Position X, at which location is the time 5 p.m.

Earth rotates west to east zonesSolar time is based on the position of the sunNIGHT IS FALLING ON EARTH

Look at the East Coast of the United States. The lights are already lit.

California the sun is still visible.

Look at Paris and Barcelona, the lights are already lit, meanwhile in London, Lisbon and Madrid the sun is still visible.

Looking south, we can see the islands in the middle of the ocean.

We have a perfect view of the British Islands, Iceland and Canada.
