Mapping the Earth
2
A globe is a scale model of the earth. It is
useful for showing the entire earth.
3
A pattern of lines circles the globe in east-west
and north-south directions. It is called a grid.
4
The east-west lines in the grid are lines of
latitude.
5
Lines of latitude are called parallels because
they are parallel to each other.
6
The equator is an imaginary line of latitude that
measures distance north and south of the equator.
7
The equator is a 0 degree line of latitude that
circles the globe halfway between the North and
South Poles.
8
Latitude lines measure distance north and south
of the equator in degrees.
9
The north-south lines are called longitude.
10
Lines of longitude are called meridians and pass
through the Poles.
11
Meridians measure distance east and west of the
Prime Meridian. The Prime Meridian is an
imaginary line that runs through Greenwich,
England.
12
The Prime Meridian represents 0 degrees longitude.
13
Latitude ranges from 0 degrees at the equator to
90 degrees North or 90 degrees South for
locations at the Poles.
14
Longitude ranges from 0 degrees at the Prime
Meridian to 180 degrees East or West.
15
The equator divides the globe into two halves
called the Northern and Southern Hemispheres. The
Prime Meridian divides the globe into Eastern and
Western Hemispheres.
16
Our planets land surface is divided into seven
large landmasses called continents.
