OVERVIEW OF THE TOPIC
BASIC UNDERSTANDINGS
Latitude – distance between two parallels measured north or south of the Equator.
Longitude– distance between two meridians measured east or west of the Prime Meridian.
Parallels– are imaginary lines running in an east-west direction around the Earth.Meridians – are imaginary lines that meet at the poles.

Lines refer to
“parallels and meridians”.
Distancesrefer to “latitudes and longitudes”.

PARALLELS AND MERIDIANS
*Imaginary
lines
*Circles help in
determining
locations
*Intersecting
*Horizontal
Lines
*Only one
Great Circle
*Run in an
east-west
direction
*Vertical Lines
*All Great
Circles
*Run from north
To south
*Determine
time zones

PARALLELS OF LATITUDE
Equator – parallel located
at the center and whose
length is equal to the
circumference of the earth.
Great Circle – largest
parallel, the only Great
Circle among the parallels.

Arctic Circle – located at 66 ½ o north of the equator. It marks the northernmost limit of the Sun’s oblique or slanting rays.
Tropic of Cancer – lies 23 ½ o
north of the equator. Marks the northernmost limit of the Sun’s vertical rays.

Equator – designated Oo
latitude, located at the center of the Earth and divides the Earth into the Northern and Southern Hemispheres.
The reference point in measuring distances north and south moving toward the poles.

Tropic of Capricorn - lies 23 ½ o south of the equator. Marks the southernmost limit of the Sun’s vertical rays.
Antarctic Circle - located at 66 ½ o
south of the equator. It marks the southernmost limit of the Sun’s oblique or slanting rays.

LATITUDE AND LONGITUDE
MERIDIANSOF LONGITUDES
Two meridians opposite each other form a Great Circle.
Meridians are arcs of Great Circles.
Meridians – line running vertically about the Earth.

Special Meridians
1. Prime Meridian – line designated Oo
longitude and which passes through Greenwich,
England. Also called Greenwich Meridian.
It is the reference point in measuring distances
eastward or westward.

Special Meridians
2. International Date Line (IDL) –directly opposite of the prime meridian in a line
designated 18Oo longitude.
It is not a straight line that deviates eastward and westward upon crossing certain places to allow land areas and island groups to have the same calendar day
