Topography and Landforms Quiz

Question 1A path rises 42 m over a horizontal run of 700 m. Calculate its average gradient in %, to one decimal place.

Enter a number in %.

Answers within 0.05 % of the expected value are accepted.

Question 2Starting on a 250 m contour, you move uphill across four contour intervals of 10 m each. Find the final contour elevation in m, to the nearest whole number.

Enter a number in m.

Answers within 0.5 m of the expected value are accepted.

Question 3On a 1:50000 map, a route measures 3 cm. Use 100000 cm = 1 km. Find its ground distance in km, to two decimal places.

Enter a number in km.

Answers within 0.005 km of the expected value are accepted.

Question 4A coastal cliff has tightly spaced contours at a low elevation. What do the close contours show?

A steep slope over a short horizontal distanceHigh ground relative to the map’s inland areasA larger vertical interval between neighboring contoursA gentle slope close to the sea-level reference

Question 5Which property describes the difference between the highest and lowest ground in an area?

Aspect: the orientation of the slope within the areaRelief: the vertical range within a defined boundaryScale: the ratio of map distance to ground distanceElevation: the height of a point relative to a datum

Question 6A hillside faces east. Which topographic property does that statement identify?

Gradient, the steepness of the slopeRelief, the range of heights in the areaDatum, the reference used to measure heightAspect, the compass orientation of the slope

Question 7A river bends north around a ridge. Which evidence should establish its flow direction?

The river’s direction toward the bottom of the printed mapThe direct bearing from the river’s source to the coastThe elevation changes along the connected channelThe change in width of the printed river symbol

Question 8Two working instruments report different heights at the same point. What should be checked first?

The number of decimal places, as an indication of which height is correctThe height reference and units used by each instrumentThe compass direction in which the instruments were facingThe instrument reporting the larger height, as a better estimate of the true value

Question 9Field observations show a valley shape associated with glacial erosion. What would strengthen that interpretation?

Rock surfaces, deposits, and the region’s history of iceThe valley’s outline viewed on a second mapThe modern place name used for the valleyFiner map linework with no additional observations

Question 10How do topography and landforms differ?

Topography describes elevation; landforms describe horizontal positionTopography classifies origins; landforms record heights and slopesTopography describes the surface; landforms identify features within itTopography describes built features; landforms describe natural terrain
