Explanation:
Let’s go step by step through the fill-in-the-blanks first, using what we know about contour lines.
1.
“Contour lines join all places that are the same h . . .”
→ Contour lines connect points of equal *height*. So the word is
height → missing word starts with
h →
height.
2.
“Contour lines are usually coloured in b . . .”
On maps, contour lines are often brown (especially on topographic maps), so
brown → starts with
b.
3.
“The numbers written onto some of the contour lines tell us their height above s . . . level.”
Height is measured above *sea level* →
sea.
4.
“When contour lines are far apart the slope is g . . .”
Far apart = gentle slope →
gentle → starts with
g.
5.
“When contour lines are close together the slope is s . . .”
Close together = steep slope →
steep → starts with
s.
6.
“When the numbers on contour lines get h . . . this shows us that the ground is rising.”
Numbers increasing = going higher →
higher → starts with
h.
7.
“‘V’ shaped contour lines show us that there is a v . . .”
V-shaped contours point *uphill* and indicate a *valley* →
valley → starts with
v.
8.
“Contour lines that run into one another show us that there is a vertical rock face or a c . . .”
When contour lines merge, it means a cliff (vertical drop) →
cliff → starts with
c.
Now, the second part: comparing slopes in diagrams A, B, and C — all at 50-metre intervals.
- Steeper slope = contour lines closer together.
- Gentler slope = contour lines farther apart.
Look at the diagrams:
-
A: The lines are fairly spaced — not too close, not too far.
-
B: The lines are very tightly packed — many lines in a small area → steep slope.
-
C: The lines are stretched out horizontally — wide spacing between them → gentle slope.
So:
- Steepest slope →
B
- Gentlest slope →
C
Final Answer:
height, brown, sea, gentle, steep, higher, valley, cliff
Steepest slope: B
Gentlest slope: C
