Transcript of What is a Map?
Globes and maps
Types of Maps
The Coordinate System:
Longitude and Latitude
1. Find each of the seven continents on the map:
North America, South America, Europe, Asia, Africa, Australia, and Antarctica.
2. Find each of the oceans on the map:
Atlantic Ocean, Pacific Ocean, Indian Ocean, and Arctic Ocean.
To learn about the Earth, two tools you can use are globes and maps.
is a model of the planet Earth as if seeing it from outer space. A globe is round and shows
. There are seven continents on Earth and four oceans.
A map is a
of the Earth shown on a flat surface. Maps are useful because you can carry them with you.
Let’s look at a map more closely…
Elements on a Map
Every map has five important elements:
Each element has a purpose:
is a directional arrow that shows cardinal and sometimes intermediate directions on a map.
tells you the purpose of the map.
shows you what symbols on the map mean.
is shown in both standard and metric measurements and show distance between objects on the map.
is a smaller map that shows a “larger” area of land around the map.
See if you can identify the parts of the map:
We can learn about directions by looking at a compass rose.
A compass rose is a circle that shows principle directions printed on the map.
It is used to display the orientation of cardinal and intermediate directions.
Why so many different maps?
(map-makers) use different
Another reason for this difference is that maps can be created to represent different
of the same places.
Identify the symbols used in the key below:
One map of Europe might show only its
Another might depict the country's different
Another map might show Europe’s
physical characteristics like rivers, mountains and deserts.
What differences do you see between these maps?
Do you see any similarities?
Look at the map on the right. Why is it so colorful?
Maps that show
countries, states, cities
are known as
show features of the Earth such as,
mountains, rivers, oceans,
What other physical features are located
on the map?
Natural resource maps
Land use maps
Population density maps
Give It A Try...
On many maps you see crisscrossing lines with numbers by them. These lines and numbers form a grid system that allows us to describe the
, or exact location of any place on Earth.
The lines running east to west around the Earth are called lines of
. They measure degrees
north and south
The lines running north to south around the Earth are called lines of
. They measure degrees
east and west
The Coordinate System
Together, lines of latitude and longitude form a grid system called the
When you state the coordinates of a place on the Earth you are giving its
Absolute location is always written:
degrees North, then degrees West.
For example, the absolute location of New Orleans is 29º N, 090º W.
is used to show the relationship of

distance on the Earth.
is half of a sphere, or ball.
People use the word to describe
of Earth. Geographers, or people who study Earth, have divided the planet into two sets of two hemispheres. These are the
hemispheres and the
Northern Hemisphere -
Southern Hemisphere - below
