2. Globe ~a model of Earth. 3. Hemisphere ~one-half of the globe
The Equator divides the Northern and Southern hemispheres. The
Prime Meridian divides the Eastern and Western hemispheres. 4.
Latitude ~locations north or south of the Equator measured by
imaginary lines. The Equator is at 0 degrees latitude; an imaginary
line that separates the northern and southern hemispheres. 5.
Longitude ~locations east or west of the Prime Meridian, measured
by imaginary lines. The Prime Meridian lies at 0 degrees longitude.
6. Grid System ~the checkered board pattern on a map that is
created by crossing lines of latitude and longitude. This grid
system helps you find the absolute location of a place. 7. Absolute
Location ~the specific location of a place; the longitude &
latitude of a location or the specific address of a location. For
example; MMS Currituck County 216 Survey Road 36.36 degrees N,
Moyock, NC 27958 75.94 degrees W 8. Projection ~how mapmakers draw
the round earth on a flat piece of paper. Mapmakers create many
different map projections, that have their own unique
characteristics. 9. Map Key ~ a code that explains lines, symbols,
and colors used on a map. 10. GIS ~a computer software program that
mapmakers use that can help them make and change maps more quickly
and easily than before. G-geographic I-information S-systems 11.
Cardinal Directions ~ basic directions on a compass rose. N
(north), E (east), S (south), W (west) This compass rose only shows
cardinal directions. 12. Compass Rose ~a device drawn on maps to
show directions. 13. Intermediate Directions ~any direction between
the cardinal directions. For example, NE (northeast) is between
north and east. This example shows both cardinal and intermediate
directions. 14. Scale bar ~a measuring line on a map that helps you
determine distances on a map. 15. Scale ~the ratio between a
distance on a map and the same distance on the earth. For example;
1 inch:20 miles 16. Relief ~changes of elevation over a given area
of land This is an example of a raised relief map. 17. Elevation
~the distance of an area above sea level. 18. Contour lines ~one
line for each major level of elevation: contour maps show levels of
elevation: contour maps are a type of physical map 19. *Relative
location* ~the location of a subject in relation to another point.
For example; Camden County is just west of Currituck County. 20.
*Review* How are political and physical maps different from each
other? Compare how they are the same 21. Political Maps ~show the
names and boundaries of countries and often identify major physical
features 22. Physical Maps ~ identify landforms and water features
Physical maps often show relief or elevation. A contour and relief
maps are physical maps.
