GED Social Studies: Places, Regions, and Map Skills Concepts

Importance ★★★★☆ · 30% (estimate)

Overview

This chapter covers the tools geographers use and the ways they divide the world into places and regions.

Most maps put north at the top. Latitude measures distance north or south of the Equator, and longitude measures distance east or west of the Prime Meridian. A map scale converts map distance to real distance, and a topographic map uses contour lines to show elevation.

A region is an area with shared features, such as climate, landforms, language, or economy. Borders can follow physical features like rivers, straight geometric lines, or cultural differences. Population density, the number of people per unit of land area, shows how crowded a place is.

Key concepts

  • Latitude and longitude

    Latitude: north-south from the Equator. Longitude: east-west from the Prime Meridian.

    Memory tipLatitude lines are flat like ladder rungs.

  • Map scale

    Shows how map distance relates to real distance. Real distance = map distance x scale.

    Memory tip1 inch = 50 miles, so 3.5 inches = 175 miles.

  • Region

    An area with shared physical or human features.

    Memory tipGreat Plains (physical), Corn Belt (economic).

  • Types of borders

    Physical (rivers, mountains), geometric (straight lines), cultural (language, religion).

    Memory tipRio Grande = physical border.

  • Population density

    Number of people divided by land area.

    Memory tip30 million / 150,000 sq mi = 200 per sq mi.

Often tested

  • Contour lines close together mean steep land.
  • Check the zeros carefully in density and scale calculations.

Practice questionReviewedGeography and the World › Places, Regions, and Map Skills★★★★☆

Question 1. What do lines of latitude measure?

  1. ① Distance between two cities
  2. ② Distance east or west of the Prime Meridian
  3. ③ Height above sea level
  4. ④ Distance north or south of the Equator
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ④ Distance north or south of the Equator

Key point: Latitude: north-south; longitude: east-west

Latitude lines run east-west around the globe and measure how far north or south a place is from the Equator (0 degrees). Longitude lines run from pole to pole and measure how far east or west a place is from the Prime Meridian.

Wrong choices

  • Distance between two cities: Distance between cities is found with a map scale.
  • Distance east or west of the Prime Meridian: Distance east or west of the Prime Meridian is measured by longitude.
  • Height above sea level: Height above sea level is elevation.

Question 2. In geography, what is a region?

  1. ① A line on a map that shows latitude
  2. ② The scale printed on a map
  3. ③ An area that shares common features, such as climate, landforms, language, or economy
  4. ④ A country's capital city
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ③ An area that shares common features, such as climate, landforms, language, or economy

Key point: Region: an area with shared features

A region is an area that has something in common that makes it different from the areas around it. Regions can be physical (the Great Plains), cultural (the Spanish-speaking parts of the Americas), or economic (the Corn Belt).

Wrong choices

  • A line on a map that shows latitude: Lines of latitude measure position. They are not regions.
  • The scale printed on a map: A map scale shows distance. It is not a region.
  • A country's capital city: A capital city is one place, not an area defined by shared features.

Question 3. On a map, 1 inch stands for 50 miles. Two towns are 3.5 inches apart on the map. How far apart are the towns in real life?

  1. ① 53.5 miles
  2. ② 150 miles
  3. ③ 175 miles
  4. ④ 200 miles
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ③ 175 miles

Key point: Map distance x scale = real distance

Work it out step by step:

  1. Each inch = 50 miles.
  2. 3.5 inches x 50 miles = 175 miles.

Check: 3 inches = 150 miles, plus half an inch = 25 miles, so 150 + 25 = 175.

Wrong choices

  • 53.5 miles: 53.5 miles adds the numbers instead of multiplying.
  • 150 miles: 150 miles is 3 inches. The extra half inch adds 25 more miles.
  • 200 miles: 200 miles would be 4 inches on the map.
