Use of Globes in studying History:
A globe is a model of Earth. It shows the actual shape, size , and location of each Landmass and
body of water.
Globes divide earth into lines of latitude and Longitude. Latitude measures distance north or
south of the Equator, which is an imaginary line around the widest part of Earth. Longitude
measures distance east or west of the Prime Meridian, which is an imaginary line running from
the North Pole to the South Pole. The diagram below shows how lines of longitude and latitude
form a grid pattern on a globe.
Using lines of Latitude and Longitude, you can locate any place on Earth. The location of 38°
north Latitude and 122° west longitude is written as 38° N/122° W. bOnly one place on the Earth
has this location: The city of San Francisco.

What is A Map Projection?
Globes are accurate, but they are not easy to carry around, and they are not useful for showing
areas of Earth in detail. So Mapmakers had to develop methods to show the curved Earth on a
flat surface. These methods are known as map projection. All map projections distort Earth in
some way. Below are two common types of map projections.
A) Mercator Projection:
In the 1500s, ocean travelers relied on the Mercator projection, named after mapmaker Gerardus
Mercator. The Mercator projection accurately shows direction and the shape of Earth’s landmass.
However, it distorts distance and size.
B) Robinson Projection:

The Robinson Projection shows the correct shape and size of landmass for most parts of
the world. However, it does not show directions as well as Mercator projection does. It
also distorts the size of the North Pole and South Pole.
Activity:
Would you use a Mercator Projection map to measure the exact distance from Rome to
China? Why or Why Not?
