Maps Review

Question 1 The Northern and Southern Hemispheres are divided by the A. Equator B. prime meridian C. Graticule D. North and South Poles The Equator is an imaginary line or circle of the Earth that is equidistant from the North Pole and South Pole. It divides the Earth into two equal parts.

Question 2 The Eastern and Western Hemispheres are divided by the A. Equator B. prime meridian C. Graticule D. North and South Poles The prime meridian is an imaginary line that runs through Greenwich, England and represents 0° longitude. Points east/west of prime meridian are 0° to 180°.

Question 3 and 5 Lines of Latitude…? A. Run from North to South B. Start in Greenwich, England C. Are parallel to the equator D. Indicate magnetic declination Lines of latitude Run parallel to equator. Show distance in degrees north/south of the equator. Latitude is thus measured from 0° at the equator to 90° at the poles.

Question 4 On the global grid, the prime meridian is at ____. A. 0 degrees latitude B. 0 degrees longitude C. 90 degrees latitude D. 90 degrees longitude The prime meridian is an imaginary line that runs through Greenwich, England and represents 0° longitude. Points east/west of prime meridian are 0° to 180°.

110 W longitude Longitude runs north and south and measures how far east or west you are from the prime meridian. Quesiton 6 How many cities on the map are located west of the 110o W Longitude? A. 2 B. 8 C. 7 D. 3

Latitude runs east to west on the globe and measures the distance north to south of the equator. Question 7 What is the closest line of latitude to Charleston? A. 80o W B. 30o N C. 40o N D. 70o W

Question 8 Which of the following connects points of equal elevation? A. Contour line B. Distortion C. Legend D. Latitude Detailed maps showing changes in the elevation of terrain are called topographic maps. Elevation is the distance above or below sea level. Elevation on a topo map is shown with contour lines. A contour line connects points of equal elevation

Question 9 Which feature would probably NOT be identified on a topographical map? A. A river B. A bridge C. A clothing store D. The tallest mountain A topographic map will show changes in elevation as discussed in question 15. (mnts) It will also show major roads, bridges, and other physical land features. Some buildings are labeled but typically only government buildings and schools. Click again for a sample map.

Question 10 In Figure 1-2, what is the elevation of Sugar Loaf Mountain? A. 11,300 feet B. 1,130 feet C. 15,00 feet D. 10,000 feet Find sugar mountain and the triangle located on the map indicates it’s summit.

Question 11 In Figure 1-2, what is the approximate difference in elevation between point E and point D? A. 7500 feet B. 750 feet C. 1000 feet D. 1500 feet Find the elevation reading on D. Notice the elevation reading on the darker Contour line in between E and D. How much did the line in between them go up. It will go up the same amount again for each dark contour index line.

Question 12 In figure 1-2, what is the contour interval of the map? A. 10 feet B. 100 feet C. 50 feet D. 25 feet The difference in elevation between two side-by-side contour lines is a contour interval. Find two elevation marked contour index lines and subtract the difference between them. Then count the number of lines between them and divide that into your difference for the interval.

Question 13 In figure 1-2, what is the distance from point B to point C A. 4 miles B. 5 kilometers C. 6 miles D. 4 kilometers Use the scale at the bottom of the page to estimate the distance. Use some scrap paper and mark the distance from the map then align it to the scale making note of the units. If your line is larger than the scale mark where it ends on the scrap paper move it forward to your mark and continue

Question 14 In Figure 1-2, what is the elevation of point E? A. 10250 feet B. 10500 feet C. 10750 feet D. 11000 feet This particular problem is easy because E fall right on a contour index line, one of the bold labeled lines. If the question did not fall on an index line but rather one of the unlabeled line you would start from an index line and determine the contour interval first (see question 12). Then for each line from the index line add the interval to you get to your desired location.

Question 15 Not counting Hawaii or Alaska how many time zones span the continental US A. 2 B. 3 C. 4 D. 5 Originally, all time on Earth was some local apparent solar time, the time on a sundial, so every city had its own time. When well-regulated mechanical clocks became widespread in the early 19th century, each city began to use some local mean solar time. The first time zone was created in 1847 by railroads on the island of Great Britain using GMT. Sandford Fleming of Canada proposed worldwide hourly time zones in 1879. A time zone is a region on Earth that has a uniform, legally mandated standard time. The US has 6 major time zones but only 4 are in the lower 48 states.

Question 16 Which is not a time zone in the continental US? (lower 48 states) A. Atlantic B. Eastern C. Central D. Mountain D. Pacific The US does have 6 major time zones with 4 in the lower 48 states.

Question 17 Denver is in Mountain time and Chicago is in Central time. If it's 7:00 P.M. in Denver, what time is it in Chicago? A. 5 Pm B. 6 Pm C. 7 Pm D. 8 Pm To go from Denver to Chicago (or Mountain to Central time) you must move to the right, towards Greenwich outside of London England. Greenwich is the beginning of any day and thus is later in the day as each time zone begins its clock 1 hour after the proceeding one. So when we move to the right through time zones we will add one hour for each time zone.

Question 18 What is the time difference between Pacific time and Eastern time? A. Pacific time is 3 hours earlier B. Pacific time is 3 hours later C. Pacific time is 2 hours earlier D. Pacific time is 2 hours later Count the jumps on the map going from Pacific time to Eastern time. Each jump is one hour. Since you’re jumping from left to right you are adding one hour for the time zones as you get closer to Greenwich England and the rising sun in the East. Thus its always Earlier the farther you get from Greenwich England. You football fans maybe able to think about Monday night football games. It’s on so late in the East so people are actually home from work in the west when it comes on live across the nation.
