Topographic Maps and Profiles Quiz

What is the significance of the contour interval on a topographic map?

• It represents the scale of the map.

• It marks the direction of north.

• It shows the change in elevation between contour lines.

• It indicates the distance between two points.

When constructing a topographic profile, what is the first step?

• Drawing a straight line across the map.

• Identifying the highest elevation point.

• Connecting all the plotted points.

• Labeling all ISO lines above the profile line.

How do you determine where to plot an 'X' on a topographic profile?

• By placing an 'X' at the highest point on the map.

• By measuring the distance between contour lines.

• By marking an 'X' at the lowest elevation.

• By plotting an 'X' at every intersection of the profile line and contour lines.

What should you do when two points on a topographic profile are at the same elevation?

• Connect them with a straight line.

• Leave them unconnected.

• Ignore them and move to the next point.

• Create a peak or valley between them.

How can you determine a possible elevation for the top of a hill?

• By measuring the distance from the base to the top.

• By estimating between the highest contour line and the next possible line.

• By checking the map's legend.

• By finding the highest contour line and adding 10 feet.

What direction does a river flow if the contour lines bend upstream?

• Northwest

• Southeast

• Northeast

• Southwest

What indicates a steep slope on a topographic map?

• Contour lines that are close together.

• A small number of contour lines.

• Contour lines that are far apart.

• A large number of contour lines.

What is the gradient of a gentle slope?

• High gradient

• No gradient

• Low gradient

• Variable gradient

How can you identify a flat area on a topographic map?

• By checking the map's scale.

• By finding areas with no contour lines.

• By looking for contour lines that are close together.

• By identifying areas where contour lines are far apart.

What is the relationship between contour line spacing and slope steepness?

• Closer lines indicate a steeper slope.

• Farther lines indicate a steeper slope.

• Closer lines indicate a gentler slope.

• Line spacing does not affect slope steepness.
