Coordinates
What are the lines that measure distance north or south of the Equator called?
What is latitude?
What does a map scale tell you?
A map scale shows the relationship between distance on the map and actual distance on Earth.
What do contour lines connect?
Lines of equal elevation.
What does a compass rose tell you?
Direction
What is the difference between a physical map and a topographic map?
A physical map shows physical features such as mountains, rivers, and lakes; a topographic map shows elevation and changes in elevation using contour lines.
What are the lines that measure distance east or west of the Prime Meridian called?
What is longitude?
On a map, 1 inch represents 5 miles. How far does 3 inches represent?
15 miles
What does it mean when contour lines are very close together?
The land has a steep slope.
If you are traveling right on a map, which direction are you moving?
What is East ?
Why are topographic maps useful to scientists and engineers?
Scientists and engineers can use them to understand elevation, slope, landforms, drainage, and terrain.
Which coordinate should be given first: latitude or longitude?
What is latitude?
A map has a scale of 1 inch = 10 miles. Two towns are 4.5 inches apart. How far apart are they in real life?
45 miles
A contour map has contour lines labeled 500 ft, 600 ft, and 700 ft. What is the contour interval?
100 ft
A location is at 40°N, 90°W. Is it in the Northern or Southern Hemisphere? Eastern or Western Hemisphere?
Northern Hemisphere and Western Hemisphere.
A hiker travels from a location at 400 ft elevation to one at 1,000 ft. What is the change in elevation?
600 ft
A location is at 30°S, 120°E. Which hemispheres is it located in?
Southern and Eastern Hemisphere
On a map, two cities are 7.2 cm apart. The scale is 1 cm = 25 km. What is the actual distance?
180 km
If contour lines form closed circles and the elevation increases toward the center, what landform is represented?
What are hills/mountains?
A student says 20°N, 75°W and 75°W, 20°N represent different locations. Are they correct? Explain.
No. They represent the same location because latitude is normally written first and longitude second.
Two hiking trails are the same horizontal distance apart. Trail A rises 200 ft, while Trail B rises 800 ft. Which trail has the steeper slope? Explain.
Trail B is steeper because it has a much greater change in elevation over the same horizontal distance.
A city is located at 45°N, 90°W. Another city is at 45°S, 90°W. How are their locations different, and what do they have in common?
Both are at 90°W longitude and 45° from the Equator, but one is in the Northern Hemisphere and one is in the Southern Hemisphere.
A road measures 12 cm on a map. The map scale is 1 cm = 8 km. A student says the road is 12 km long. What is the correct distance, and what mistake did the student make?
96 km. The student incorrectly assumed the map measurement and real-world distance were the same.
What are the two rules of contour lines?
1. Lines can never cross
2. Lines must have the same elevation around
You are planning a road between two towns. Route A crosses several areas where contour lines are extremely close together. Route B follows an area where contour lines are widely spaced. Which route would likely be easier to build and why?
Route B would likely be easier because widely spaced contour lines indicate a gentler slope.
SHOW MAP - Which area would be the safest location to build a road, and what evidence from the contour lines would you use to defend your choice?
