Download Latitude and Longitude - Northside Middle School

 Measurement
in degrees North or South of
the Equator
 There are 90° both N and S of Equator
 Positions of latitude above the equator are
called “North” and are in the Northern
Hemisphere
 Positions of latitude below the equator are
called “South” and are in the Southern
Hemisphere
 Torrid
Zone- region between 23.5°N and
23.5°S

Only region on the Earth where the sun can be
directly overhead at zenith (at a 90° angle)
 The
position of the sun in the sky changes
with latitude.



The higher the sun, the lower the latitude
The lower the sun, the higher the latitude
Type of relationship?
 Lines
of latitude are parallel to the equator
 There are 90° of latitude North and South of
the equator
 The equator is 0°
 The equator divides the earth into 2 equal
parts
 Latitude is: ____________________________
 Anywhere
in the Northern Hemisphere only, your
latitude is equal to the altitude of Polaris (the
North Star)
 Define Altitude:
a)
b)
c)
d)
Always rises at sunset and sets at sunrise
Is located over Earth’s axis of rotation
Can be seen from any place on Earth
Is a very bright star
a)
b)
c)
d)
52ºS
90ºS
52ºN
90ºN
Polaris is located directly over the tropic
of cancer
b) Polaris is the brightest and most easily
located star
c) The altitude of Polaris is equal to the
observers latitude
d) The position of Polaris changes with the
seasons
a)
 Longitude
is the degrees of measure East or
West of the Prime Meridian, 0°
 The Prime Meridian passes through
Greenwich, England
 Lines of longitude connect the North and
South pole and are measure in degrees East
or West
 There are 180 degrees of longitude East or
West of the Prime Meridian
 Prime


Meridian  0°
Where the time zones are based off of
GMT or Greenwich Mean Time
 International


Date Line  180°
Where the date changes
In the middle of the pacific ocean
 The
earth rotates 360° in 24 hours
 Calculate rate of rotation:
 Each
time zone is a change in 15° of
longitude
 15° longitude of movement is equivalent to 1
hour of time
 Longitude
lines connect the North Pole with the
South Pole
 The line of 0° longitude is the Prime Meridian
 Longitude lines give directions East or West of
the Prime Meridian
 There are 180° of longitude East or West of the
Prime Meridian
 Define longitude:
