Ch.2 Vocab Flashcards
lines drawn on a topographic map to show elevation, and which connect all the places that are the same elevation
Contour lines
changes in elevation for a given region
Topography
figure on a map or nautical chart for displaying locations of north, south, east and west
Compass rose
imaginary horizontal line drawn around the Earth parallel to the equator
Latitude
difference in height of landforms in a region
Relief
a map projection made by projecting Earth’s three dimensional surface onto a cone wrapped around an area of the Earth
Conic map
map projection made by projecting onto a flat paper from just one spot on the Earth
Gnomonic map
imaginary vertical line drawn on the Earth from pole to pole
Longitude
the constant difference in elevation between two contour lines on a topographic map
Contour interval
map projection created using a cylinder wrapped around the Earth
Mercator projection
orbit that moves over Earth’s north and south poles as Earth rotates underneath
Polar orbit
a special type of map that shows the elevations of different geologic features of a region
