_{If you are located on zero degrees latitude, then you are on the __________________.}
equator

_{Lines of longitude run ________ and _________.}
north, south

_{The prime meridian lies at ____ degrees _________________.}
0, longitude

_{The prime meridian passes through ____________, England.}
Greenwich

_{Longitude is measured in degrees ________ or ________ of the prime meridian.}
East, West

_{Latitude is measured in degrees _______ or ________ of the equator.}
North, South

_{One degree of latitude equals}
3600 seconds

One minute of longitude equals
60 seconds

One degree of longitude equals
60 minutes

_{Topographic maps that are bounded by lines of latitude and longitude are called
____________ maps.}
quadrangle

_{How many 7.5 minute quadrangles occur within a 15 minute sheet?}
4

_{Where would you find the title of a 7.5 minute quadrangle?}
top right corner

_{Where would you find the scale of a 7.5 minute quadrangle?}
middle lower margin.

_{A 7.5 minute quadrangle covers how many degrees of longitude and latitude?}
7.5 minutes of both longitude and latitude

_{On a 7.5 minute quadrangle where can information about magnetic declination be found?}
lower left margin.

_{How many feet are there in an inch on a map if the scale is 1:24000?}
 2000 feet in an inch  Use the relationship that there are 12 inches in a foot. Hence, 24000
 inches divided by 12 inches yields 2000 feet.

_{How many feet are there in an inch on a map if the scale is 1:12000?}
1000 feet. See answer to question 24 for explanation of how to calculate this value.

_{Magnetic North lies in what direction relative to geographic North if the magnetic
declination is 14 degrees East?}
14 degrees east of geographic north

_{What is the Bruton compass used to measure?}
directions

_{The North end of the compass needle ALWAYS points toward what direction?}
magnetic North

_{If the magnetic declination is properly adjusted, then when the compass needle reads zero
degrees, the sighting arm points in what direction?}
North

_{The index pin is used to adjust what feature on the Bruton compass?}
The index pin is used to adjust the circular grid for magnetic declination

_{Is magnetic North a stationary fixed point on the globe?}
No, magnetic North is constantly moving.

_{Topographic contour lines that are closer together than other contour lines indicate what?}
steeper slopes

_{If you were asked what do individual topographic contours on a given 7.5 minute
quadrangle indicate, how would you respond?}
 Each topographic contour represents a curve of equal elevation. In other words, if you were
 to walk along a given contour, then you would be walking along a horizontal surface

_{What do contour lines that are uniformly spaced indicate?}
a constant slope
