Which side view shows the land along the line from A to B?
A contour map with a line every 10 m of height. North is at the top. A hilltop, 159 m, in the middle. The bottom of a hollow, 80 m, in the middle. The line runs from A, at the top, to B, at the bottom left.
Walk along the line from A to B and read each contour line it crosses: 100 m ↓, 90 m ↓, 90 m ↑, 100 m ↑, 110 m ↑, 120 m ↑, 130 m ↑, 140 m ↑, 150 m ↑, 150 m ↓, 140 m ↓, 130 m ↓, 120 m ↓, 110 m ↓.

How this data is usedHelp
Each contour line joins places at the same height, and neighbouring lines are 10 m apart in height. Lines close together mean steep ground, and lines far apart mean gentle ground. Rings whose heights rise towards the middle are a hill. Rings with short ticks, whose heights fall towards the middle, are a hollow: the ticks point downhill. To find the side view along a line, note the height wherever the line crosses a contour line. Every answer is worked out from the same land that drew the map, so each question has exactly one right answer.
Each round has six questions and no time limit. Choosing an answer locks it. Review the steps, then move to the next question. Finish all six to save the round. Active time includes reviewing the steps, but does not count time when this page is hidden. Speed does not affect your score.
Use Tab and Enter or Space to choose an answer. The number keys also select answers, except when another control is focused. After an answer, Enter goes to the next question.
Original practice puzzles, not a standardized assessment.
About this practice
A practice in reading the shape of the land from a map. Each contour line joins places at the same height, so the pattern of the lines shows hills, hollows and slopes.
