11. Vertical Chart Relief - N2

Question 1

A contour line connects?

Answer 1

On a map or chart a contour line positions of equal height.

Question 2

Three methods of depicting relief on a map are? (5)

Answer 2

• Colouring,
• shading,
• hatchures
• contour lines
• spot heights

Question 3

What are contours?

Answer 3

Contours are continuous lines drawn on maps of equal elevation.

Question 4

What are Form Lines?

Answer 4

Contour Lines are replaced with Form Lines where an accurate survey of the terrain has not been carried out

-shown as broken (dashed) lines and indicate approximate elevations.

Question 5

What are Hachures?

Answer 5

Short lines that radiate away from high ground

• an older method used to indicate hill features in areas that have not been fully surveyed or when detailed information is not required

Question 6

What is a spot elevation?

Answer 6

A dot position indicator with the elevation printed alongside it.
It marks the location of the highest points

Question 7

The space between the contour lines depends on?

Answer 7

• The scale of the map.
• The range of elevations displayed on the map.
• The units of measurement being used.
• The gradient is assessed by the proximity of the
  contour lines - the closer they are to each other,
  the steeper the slope.

Question 8

What is tinting?

Answer 8

The visual indication of vertical relief produced
by contour lines may be enhanced by tinting the
intervening layers.
