Globes are models of the Earth that accurately show the shapes and locations of landmasses and bodies of water. They depict lines of latitude and longitude that form a grid system and allow any place on Earth to be precisely located. While globes are accurate, they are not practical to carry or show detail. Map projections, like the Mercator and Robinson, were developed to show the spherical Earth on a flat surface, but inevitably distort some aspects of size, shape, or direction.

- 1. 1 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. SOTH ASIAN HISTORY 2ND SEMESTER LL.B.

What would be some advantages and disadvantages of using Globe? __________________________________________________________________ ____________________________________________________________________ ___________________________________________________________________ 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:
- 3. 3 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?
