Types of Maps Political Maps Physical Maps Thematic Maps
Shows the borders that divide nations from one another. Physical Maps Uses colors or contour lines to show difference in elevation. Thematic Maps Emphasizes a single resource or piece of information.

Features of a Map Map Title: Tells what the map is about.
Map Key (Legend): A table used to explain what symbols mean on a map or chart. Compass Rose: a marker that indicates direction on a map. Map Scale: Used to measure distance on a map.

Location, Location, Location
Location is the position on the Earth’s surface. Types: 1a.) Absolute Location: the exact position of a place on the earth’s surface. 1b.) Relative Location: location in relation to other places

1a.) Absolute Location Found using a grid system of number lines.
You are here Found using a grid system of number lines.

Lines of Latitude or south of the equator Also called
Measures north or south of the equator Also called parallels because they are parallel to the Equator. North Pole = 90° N South Pole = 90°S Equator divides earth into two hemispheres. Northern Hemisphere Southern Hemisphere

Lines of Longitude Measures east or west of the Prime Meridian (Greenwich, UK) Also called meridians, which intersect at the poles. 180° = International Date Line Prime Meridian on one side/IDL on the other. PM/IDL divides earth into two hemispheres Western Hemisphere Eastern Hemisphere

When crossing the date line add
When crossing the date line, add a day going west, and subtract a day going east.

Reading the Global Grid
Y X = Equator & Parallels X Y = PM, IDL & Meridians

North West East South

Y X Read x first, then y second. (x,y)

Cultural Landscapes:

Human/Environmental Interaction

Cultural Interaction Cultural Diffusion: the spread of ideas and cultures as people move and interact with each other.
