To find the coordinates for each point, we need to look at two things:
1.
Latitude: How far North or South of the Equator (the middle horizontal line) the point is.
* Lines above the Equator are North (
N).
* Lines below the Equator are South (
S).
2.
Longitude: How far East or West of the Prime Meridian (the middle vertical line) the point is.
* Lines to the right of the center are East (
E).
* Lines to the left of the center are West (
W).
The grid lines are spaced every
30 degrees. Let's count them out from the center (0°, 0°).
Step-by-Step Calculation:
*
Point A:
* Latitude: It is on the first line below the Equator. That is
30° S.
* Longitude: It is on the fourth line to the right of the center. $30 \times 4 = 120$. So,
120° E.
* Result:
30° S, 120° E
*
Point B:
* Latitude: It is on the second line below the Equator. $30 \times 2 = 60$. So,
60° S.
* Longitude: It is on the first line to the left of the center. That is
30° W.
* Result:
60° S, 30° W
*
Point C:
* Latitude: It is on the second line above the Equator. $30 \times 2 = 60$. So,
60° N.
* Longitude: It is on the second line to the left of the center. $30 \times 2 = 60$. So,
60° W.
* Result:
60° N, 60° W
*
Point D:
* Latitude: It is on the first line below the Equator. That is
30° S.
* Longitude: It is on the first line to the left of the center. That is
30° W.
* Result:
30° S, 30° W
*
Point E:
* Latitude: It is on the third line above the Equator. $30 \times 3 = 90$. This is the North Pole, so
90° N.
* Longitude: At the exact North Pole, all longitude lines meet, but on this map, it sits directly on the central vertical line. So,
0°.
* Result:
90° N, 0°
*
Point F:
* Latitude: It is on the third line above the Equator. $30 \times 3 = 90$. This is the North Pole, so
90° N.
* Longitude: Like Point E, it is at the pole on the central line. So,
0°.
* Result:
90° N, 0°
*
Point G:
* Latitude: It is on the first line above the Equator. That is
30° N.
* Longitude: It is on the third line to the left of the center. $30 \times 3 = 90$. So,
90° W.
* Result:
30° N, 90° W
*
Point H:
* Latitude: It is on the first line above the Equator. That is
30° N.
* Longitude: It is on the second line to the right of the center. $30 \times 2 = 60$. So,
60° E.
* Result:
30° N, 60° E
*
Point I:
* Latitude: It is on the first line below the Equator. That is
30° S.
* Longitude: It is on the fifth line to the right of the center. $30 \times 5 = 150$. So,
150° E.
* Result:
30° S, 150° E
Final Answer:
A. 30° S, 120° E
B. 60° S, 30° W
C. 60° N, 60° W
D. 30° S, 30° W
E. 90° N, 0°
F. 90° N, 0°
G. 30° N, 90° W
H. 30° N, 60° E
I. 30° S, 150° E
