contour lines

Question 11

Answer 11

4
North - N
East - E
South - S
West - W

Question 12

What are the main directions also called

Answer 12

Cardinal points

Question 13

When maps are drawn with what is North indicated

Answer 13

With an arrow or marker

Question 14

What do you find between these cardinal points

Answer 14

4 intermediate points

Question 15

Name the four intermediate points

Answer 15

Northeast - NE
Southeast - SE
Southwest - SW
Northwest - NW

Question 16

What is a map scale

Answer 16

The scale is the amount by which things are made smaller. It tells us how much smaller the map is than the real area
The scale also compare the distance between 2 place on the map with the real distance between the same 2 places on the ground.

Question 17

How many types of scales are there

Answer 17

3

Question 18

Name the 3 types of scales

Answer 18

Word Scale ( statement)
Ratio Scale
Linear Scale

Question 19

Describe a word scale

Answer 19

A word Scale gives the scale in words for example one centimetre on the map represents one kilometer on the ground

Question 20

Describe a ratio Scale

Answer 20

A ratio scale uses numbers to give the relationship between the map distance and the real ground distance: example 1:100 000

Question 21

Which rules must you follow to converts a word scale to a ratio scale

Answer 21

1) A ratio scale must always start with 1
2) The measurements before and after the colon : must be in the same unit
example:
scale 4 cm equals 2 km
1st convert 2 km to cm (2 x 100 000 = 200 000)
then divide 4 by 4 (=1) (remember to divide the 200 000 by 4 (=50 000)
answer then is 1:50 000

Question 22

Describe a linear scale

Answer 22

A linear scale consists of a line divided into primary units, with secondary units to the left of the 0
primary units to the left of the 0 must be same legnth as the primary unit to the right of the 0

Question 23

how do you convert 1 000 000 mm in 1 km

Answer 23

mm to km you divide by 1 000 000

Question 24

how do you convert 100 000 cm to 1 km

Answer 24

cm to km you divide by 100 000

Question 25

how do you convert 1 000 m to 1 km

Answer 25

m to km you divide by 1 000

Question 26

how do you convert 100 cm to 1 m

Answer 26

com to m you divide by 100

Question 27

how do you measure distance on a map

Answer 27

measured by 2 ways

1) along straight line
2) along curved line

Question 28

how do you measure along a straight line on a map

Answer 28

Use your rules

Question 29

how do you indicate height on a map

Answer 29

on topographic maps we use symbols to show altitude. Symbols are:
Spot Height - Shows the actual height of a particular point
Bench Mark - Is a spot height shown along a road or a railway line
Trigonometric beacon - Is built to mark the height of the land at a certain point

Question 30

When contour lines are close together it shows?

Answer 30

a steep slope

Question 31

When contour lines are far apart is shows?

Answer 31

a gradual slope

Question 32

How is valleys indicated on a map

Answer 32

With a V pattern along valleys

V’s always point upstream; indicating the direction of the stream flow

Question 33

Does streams flow uphill or downhill

Answer 33

Downhill

Question 34

Can contours cross streams

Answer 34

Yes

Question 35

Contour lines make shapes and patterns on a map what does it identify

Answer 35

Identify different features

Question 36

What does it mean when the contour lines is closer together

Answer 36

The slope is steeper

Question 37

What does it mean when contour lines is far apart

Answer 37

The slope is gentler

Question 38

What does concurrency mean

Answer 38

Contour lines never cross or divide

Question 39

What does cliffs mean

Answer 39

May appear to merge on vertical cliffs but are stacked

Question 40

How do you draw contour lines

Answer 40

1) Draw line between 2 points on desired area
2) Place folded sheet of paper along line
3) Mark each contour line intersecting the paper
4) indicate the vertical height with a dot on a scale form each mark
5) connect the height dots with a smooth line
