READ ABOUT IT!

Activity 2:  Read the Lesson 3 Text below.  Match the vocabulary words and their definitions in your Lesson Chronicles under the Lesson Vocabulary header.  

THEMATIC MAPS

A thematic map is a map that focuses on one main idea or theme and uses colors or pictures to show how different places relate to each other in regards to that theme.  There are many different ideas that thematic maps show about regions.  Some of these are natural resources, vegetation areas, population, types of soil, climate, and temperature.  
Thematic maps display information about a region using colors, pictures, and symbols.  Look at the examples below.

Types of Thematic Maps

Choropleth Maps
Below you will see different examples of choropleth maps.  A cloropleth map is a thematic map in which areas are colored or shaded to represent similarities and differences in the theme.
Picture
​This map shows the different areas that refer to softdrinks as Pop, Soda, or Coke.  Notice how small blocks of color represent each county in the U.S.  Do you see the mistake in this map?  (Hint:  Look at the Legend and then at the map.)
Picture
​This map shows the times that polls closed across the nation in the 2012 elections.

Isoline Maps
Below you will see different examples of isoline maps.  A isoline map is a thematic map where lines are drawn to link different places that share a common theme and filled in with color to show contrasts of the theme. 
Picture
The map above does a wonderful job of showing the lines that connect areas with the same temperature and filled in with color to show the contrasts in temperature.  Have you seen a map like this before?  Who might use this type of map on a regular basis?

map title:  the largest or first words on the map that tell the theme of the map or what the map is about

compass rose: the symbol on the map that shows you cardinal directions and intermediate directions

cardinal directions: the basic directions of north, south, east and west

intermediate directions: northwest, northeast, southwest, and southeast


map key or legend: the part of the map that explains what the symbols an colors of the map represent

map scales: show the ratio to which the map was scaled down in size

grid system:  a coordinate plane system on a map that uses vertical lines called longitude and horizontal lines called latitude, to pinpoint locations on Earth

Lines of latitude: imaginary horizontal lines around the earth that measure north-south position between the North and South Poles

equator: an imaginary line around the earth that is located at 0 degrees latitude

North Pole:  an imaginary line of latitude around the earth that is located at 90 degrees north

South Pole: an imaginary line of latitude around the earth that is located at 90 degrees south


lines of longitude: imaginary vertical lines that measure east-west position between the North and South Poles

prime meridian:  an imaginary vertical line of longitude that is assigned the value of 0 degrees and runs through Greenwich, England
Picture
The map above shows the differences in precipitation across the United States.  Precipitation is any form of water that falls from the sky to the ground.  Precipitation can be rain, snow, sleet, or hail.  Which area has the most precipitation?
Picture
The map above shows the weather across the United States on a specific day.  Weather is what the forecasters on the TV news predict each day. They tell people about the temperature, cloudiness, humidity, and whether a storm is likely in the next few days.  It is the mix of events that happens each day in our atmosphere. Weather is not the same everywhere. It may be hot and sunny in one part of the world, but freezing and snowy in another.  This particular map shows air pressure, fronts, temperatures, and precipitation across the United States one day.
Picture
The map above shows the differences in climate across the United States.  Climate is the average weather in a place over many years.  Can you explain the difference in weather and climate?

Dot Density Maps

Below you will see different examples of dot density maps.  A dot density map is a thematic map where dots are used to show how concentrated an area is in regard to the theme.
Picture
The map above shows the concentration of public libraries over the United States.  What is meant by the word, "concentrated?"  How would use describe it based upon what you see in the map above?
Picture
The map above shows the amount of time people spent on Facebook in the United States.  Which areas visit Facebook the most?  Which areas visit Facebook the least?

Graduated Symbol Maps
Below you will see different examples of graduated symbol maps.  A graduated symbol map is a thematic map 
that uses a symbol in different sizes to show amounts.
Picture
The map above uses red circles to show the busiest airports in the United States.  The bigger the red circle, the busier the airport.
Picture
The map above uses peach colored circles to show the areas that use the most oil in the United States.  Bigger circles show that more oil is used in that area.

Flow Maps
Below you will see different examples of flow maps.  A flow map is a thematic map that shows the movement of goods, people, and ideas between places by drawing lines connecting those places.
Picture
The flow map above shows the numbers of people who moved to the United States by continent in 2007.
Picture
The map above shows the path of the Ebola virus spreading around the world.  Where did the Ebola virus start?  Which country had the most people affected by the Ebola virus after it spread?

Parts of a Map

There are 5 major major parts to a map.  These are:
  • Title
  • Compass Rose
  • Key or Legend
  • Scale
  • Grid System
The Title
The first thing you should look at when reading a map is the map title.  The map title is the largest or the first words on a map that tells you the theme of the map or what the map is about.

When a map does not have a title it can be difficult to understand what the map is telling you. 

The Compass Rose
The compass rose is the symbol on the map that shows you cardinal directions and intermediate directions.  Cardinal directions are the basic directions of north, south, east and west.  Intermediate directions are northwest, northeast, southwest, and southeast.  Intermediate directions combine cardinal directions to be more specific about a place's location on the map.
Picture
The title of this map is "World Climate Regions."
Picture

The Key or Legend
The map key or legend is the part of the map that explains what the symbols an colors of the map represent.   It is usually found in a box somewhere on the map.

​

Picture
The Scale
Map scales show the ratio to which the map was scaled down in size.  Maps are scaled down so that they fit on the available paper or screen. When scaling down a map, every part of the map is scaled by the same amount to make sure every object on the map is the same proportion as everything else on the map.
Picture

The Grid System
The grid system of a map uses vertical lines called longitude and horizontal lines called latitude, to pinpoint locations on Earth.  The location of a place is the point at which a line of latitude and line of longitude intersect.
Picture
Lines of Latitude
Lines of latitude are imaginary lines that measure north-south position between the North and South Poles. The equator is located at 0 degrees latitude.  The North Pole is located at 90 degrees north and the South Pole is located at 90 degrees south. Lines of latitude are all parallel to each other so they are often called parallels.  Lines of latitude are horizontal lines.
​
Picture
Lines of Longitude
Lines of longitude are imaginary lines that measure east-west position between the north and South Poles.  They are sometimes called meridians.  The prime meridian is assigned the value of 0 degrees, and runs through Greenwich, England. Meridians to the west of the prime meridian are measured in degrees west and those to the east of the prime meridian are measured to by their number of degrees east.
