cardinal directions
Terms Definitions
Goode's
equal area projection, accurately presents size and shape of continents; distances are less accurate - especially oceans
longitude
distance measured in degrees East or West of the Prime Meridian at 0° longitude; they are meridians that run North to South from pole to pole
hemisphere
half of a sphere (a sphere is a globe or round object like a ball)
projection
a way of drawing the round earth on a flat piece of paper
latitude
distance measured in degrees North and South of the Equator at 0° latitude; they are parallel lines that circle the earth
Robinson
shows both size and shape quite accurately; shapes of continents appear like they are on the globe
Mercator
shows land shapes fairly accurately, but not size or distance; it does show true direction
grid system
lines of latitude and longitude that cross each other; examples are graph paper, checkers board, tic-tac-toe grid, tiles on the floor, etc.
parallel lines
lines that circle the earth East to West but never touch or cross
meridian lines
the lines that circle the earth, North to South and cross at the North and South poles
absolute location
knowing a place's latitude and longiude allows you to locate it exactly on a map or globe (by naming the latitude and longitude lines that cross nearest to that location
scale
tells you what distance on the earth is represented by the measurement on the scale bar
key
explains the symbols used on the map
scale bar
a measuring line that helps you find a distance on a map
cardinal directions
North, South, East, and West
intermediate directions
directions that fall between the cardinal directions; they are NE, NW, SE, and SW
compass rose
the direction marker that shows you where the cardinal directions (N, S, E, and W) are on a map
relief
colors and shadings that show how flat or rugged the land surface is
elevation profile
a cutaway diagram that shows the sides of level land, hills and steep mountains (think of looking at the side of a piece of cake and seeing all the layers
climate region
broad areas that have the same climate (climate is the weather over a period of time)
population density
the average number of people living in a square foot or square kilometer
elevation
height above sea level
contour lines
lines that show elevation on a map, one line for each major level of elevation (all the land at the same elevation is connected by a line)
North Pole
90° N
South Pole
90° S
The Arctic Circle
23½ ° N
The Antarctic Circle
23½ ° S
The Tropic of Cancer
66½ ° N
The Tropic of Capricorn
66½ ° S
Equator
0° latitude
Prime Meridian
0° longitude
