7 Continents and 4 Oceans
What is a continent?
What is an ocean?
Continent
• One of the main landmasses of the
globe
• The mainland, as distinguished from
islands or peninsulas.
• A continuous tract or extent, as of
land.
Ocean
• The vast body of salt water that
covers almost three fourths of the
earth's surface.
• The continuous body of salt water
that covers 72 percent of the Earth's
surface.

Hemispheres
Hemisphere
•“Hemi” means half.
•“Sphere” means 3D circle or
our globe.
•So hemisphere means half of
the globe.
THE EQUATOR
• The Earth is divided into a northern half and a
southern half by an imaginary line called the
equator
• These
halves are
called
hemispheres
If your body was a globe, the equator
would be your waist!
Prime Meridian
• The Prime Meridian is an imaginary line that
connects the North Pole
and the South Pole on one
side of the Earth.
• It runs through a place
called Greenwich
(pronounced Gren’ich),
England.
• If your body was
a globe, the
Prime Meridian
go from the top
of your head to
your feet on the
front side of your
body.
International Date Line
• The International
Date Line is an
imaginary line that
runs from the North
Pole to the South Pole
on the opposite side of
the earth from the
Prime Meridian.
• On your body
globe, the
International
Date Line
would be from
the top of your
head to your
feet on the
backside of
your body
Eastern and Western Hemispheres
• The Prime Meridian and the International Date
Line divide the Earth into two more
hemispheres
The Earth has 4 Hemispheres

Latitude and Longitude lines
Latitude and Longitude Lines
• Latitude and
longitude lines
are imaginary
lines on the
earth’s surface
that make up a
grid.
Why are Latitude and Longitude Lines
Measured in Degrees?
• In math, circles are
measured in degrees.
• There are 360° in a
circle
• Since the earth is
basically circular it
was decided to
measure latitude and
longitude in degrees.
Equator
• The first line of
latitude is the
Equator=0°
• All other lines of
latitude are
measured in degrees
North or South of the
Equator
Latitude Lines
• Latitude lines run
east and west
around the globe
• They tell you a
location’s distance
north or south of
the equator
Latitude Lines
• Think of latitude lines
like the rungs of a
ladder
• Lat/Fat
• They are parallel lines
Prime Meridian
• The first line of
longitude is the
Prime Meridian=0°
• All other longitude
lines are measured in
degrees East or West
of the Prime
Meridian
Longitude Lines
• Longitude lines run
from north to south
around the globe
• They tell you a
location’s distance
east or west of the
Prime Meridian
Longitude Lines
• When you think of
longitude lines think
of tall telephone
poles
• Remember longitude
lines run from pole to
pole
• LONGitude
To Find Latitude
For example 60 °N
1. Go to your starting line (the Equator)
2. Determine which direction you must go (north
or south)
3. Determine the distance in degrees you must go
(60)
To Find Longitude
For example 40°E
1. Go to your starting line (the Prime Meridian)
2. Determine which direction you must go (east or
west)
3. Determine the distance in degrees you must go
(40)
How to use Longitude and Latitude
• When listing latitude
and longitude place
the latitude
coordinate first
• Remember to include
the direction with the
number
Example:
60°N, 40°E
Finding Coordinates
• Find the place where the latitude and longitude lines
intersect and you are done!
