Aim: Latitude and Longitude

Objective: Ability to distinguish latitude from longitude

Vocabulary

• Latitude• Longitude• Prime Meridian• Equator• NEWS• Eastern Hemisphere• Western Hemisphere

Lines of Latitude•Run parallel to the equator

•Lines Above the equator are marked NORTH

• Lines below the equator are marked SOUTH

Lines of Latitude•Notice how the latitude lines are labeled

•20 N is not the same as 20 S

Lines of Latitude•The actual North Pole is 90 N

•The actual South Pole is 90 S

Lines of Latitude•Although the lines of latitude are all parallel

•The equator is the longest “line”

This example shows that if you draw an angle from the center of the earth – on can “see” how the lines of latitude were originally configured

Longitude

• Run North and South• Only touch at the

Poles• The yellow line is the

PRIME MERIDIAN• To the left of the PM

is EAST• To the right of the PM

is WEST

Longitude

• To the left of the PM is West

• To the right of the PM is East

• We live in the Western Hemisphere

Longitude

• Notice the equator intersects the Prime Meridian

• Is the pink dot on a N or S latitude

• Is the pink dot on a E or W longitude

• …and the white dot…

Longitude

• …and the white dot… • Is it Nor S, E or W• …and the purple dot

typically the latitude is given first

Example: the white dot is 210N latitude and 1160E longitude

Or just 210N 1160E

What are the coordinates of the

•Yellow dot

•Blue dot

•Red dot

•Green dot

•Purple dot

•Black dot

Review

• The longest line of latitude is ______.• Lines of Latitude are _______ .• Do lines of latitude ever meet?• We live in the _____ hemisphere.• The two ______ are divided by the _____

meridian.• Where do longitudinal line intersect, if at

all?
