Maps VS Globes
-2-D method of showing the 3-D Earth-Distorts size of continents and oceans since it is flat
In Maps
Maps VS Globes
-Does not distort shape of the Earth-Can have ridges to show changes in elevation
In Globes
Maps VS Globes
-Lines of longitude and latitude-Absolute location-Compass rose-Find places and directions
Found in Both
Parts of a Map
CompassRose
-Is a design on a map that shows direction
Legend-Is a small table accompanying the map
that explains the symbols that are used on the map
Lines of Longitude-Lines that run from north to south, 0
degrees is located in Greenwich England known as the Prime Meridian
Lines of Latitude-Lines that run from east to west, 0
degrees is the Equator
Scale-Is the ratio between the distance between 2 points found on a map
compared to the actual distance of these points in the real world
Map Projections• Map Projections: A map projection is
a way of showing the curved surface of Earth on a flat map
-Mercator Projection-Homolosine Projection
-Robinson Projection
Mercator Projection• Named after
mapmaker Gerardus Mercator
• Accurately shows direction and shape of Earth’s landmasses
• Distorts distance and size
Homolosine Projection
• Developed in 1923 by John Paul Homolosine
• Projects equal area• Distorts ocean size
to not distort continent size/shape
Robinson Projection• Developed by Arthur
H. Robinson in 1963• Shows correct shape
and size of landmasses for most parts of the world
• Does not show direction as well as Mercator
• Distorts size of North and South Pole
What different maps do we use to see natural and human made
features?
• Political Maps-Shows the features people have created such as cities, states, provinces, territories or countries
What different maps do we use to see natural and human made
features?
• Physical Maps-Shows the landforms and bodies of water found in particular areas; colors are used to show elevation
What different maps do we use to see natural and human made
features?
• Thematic Maps-These maps show certain information about a place or region
How have maps changed overtime?
• The first map dates back to 2300 B.C• As explorers mapped the world, the
maps changed with them• Most modern maps are made with
GPS (Global Positioning Systems)
