• I personally believe that U.S. Americans are unable to do so because some people out there in our nation don’t have maps. And I believe that education, like such as in South Africa and the Iraq, everywhere, like such as, and I believe that they should…our education over here in the U.S. should help the U.S. or should help South Africa and the Iraq and the Asian countries. So we will be able to build up our future for our.

Maps and Globes Most globes and maps tell us how much smaller
they are than the Earth on their "scale,” which is found in its legend or map key. Scales are stated as a ratio.
Question: What is the ratio for this map?
![Page 11: Maps and Globes. Why can’t one fifth of Americans locate the U.S. on a map?](https://reader035.vdocuments.mx/reader035/viewer/2022062801/56649e845503460f94b86421/html5/thumbnails/11.jpg)

The first number of a ratio – generally, a "one" – represents the real thing. A colon is the ratio sign.
1: 10,000
![Page 13: Maps and Globes. Why can’t one fifth of Americans locate the U.S. on a map?](https://reader035.vdocuments.mx/reader035/viewer/2022062801/56649e845503460f94b86421/html5/thumbnails/13.jpg)

The second number tells you how many of the model are needed to equal the real thing.
1 : 10,000

If the real thing and its model have a one to one ratio (for example, these models of a heart and a real heart) it takes only one of the model to equal the real thing.

If the ratio is one to four, it takes four of the model to equal the real thing. Stated as a ratio – one to four, or 1:4.

The great circle of the earth that is equidistant from the North Pole and South Pole is the equator. Imaginary lines around the Earth that are parallel to the equator are lines of latitude. The equator divides the Earth into the north and south hemispheres. The tropic of Cancer 23 ½ ° north of the equator. The tropic of Capricorn is latitude 23 ½ ° south of the equator. A map scale shows the ratio of distances on a map to the distances on the earth. North, south, east, west are cardinal directions.
