Question 2

Precis Maps

Answer 2

Provide a clear summary of the area that a map portrays

Question 3

Latitude

Answer 3

Distance of a point north or south of the equator. Horizontal line. Written first: N(degrees)S(degrees)

Question 4

Longitude

Answer 4

Distance of a point east or west of the prime meridian. Vertical line. Written second - E(degrees)W(degrees)

Question 5

Scale

Answer 5

Relationship between distance on a map + corresponding distance on the ground
↑map scale = ↓reference number = ↑detailed
E.g., 1:10 scale is larger than 1:250000 scale

Question 6

Direction

Answer 6

Uses cardinal (NSEW) and (NE SE SW NW) points + measurements

Question 7

Question 9

Northings

Answer 9

Vertical axis - increase from South to North

Question 10

Question 11

Relief

Answer 11

Shape of the land

Question 12

Local relief

Answer 12

Difference between the highest and lowest points in a given area

Question 13

Gradient

Answer 13

Rise/Run

Question 14

Vertical exaggeration

Answer 14

Vertical scale/horizontal scale

Question 15

Density

Answer 15

The amount of something within a given space. number of feature/area

Question 16

Large scale vs small scale

Answer 16

‘Large’ or ‘small’ refers to the amount of detail. Small-scale = world map. Large scale = map of a suburb. 1:10 is a large scale, 1:100 000 is small scale.

Question 17

Vertical exaggeration formula

Answer 17

HS/VS. MUST BE IN SAME UNITS (E.G. M) –> WRITE AS [number] x (times)

Question 18

Rate of change formula

Answer 18

Change in time variable

Question 19

Proportional or % change

Answer 19

1. calculate difference betwn 2 no’s you’re comparing to get increase
2. Divide increase by og no + multiply answer by 100

                                     Change Proportional/%change     -----------              x 100
