Page 35
Soweta (SA) 35 B2 26 S 28 E
(which country is this place found)
SA
Soweta (SA) 35 B2 26 S 28 E
(which latitude position is this place)
26 S
Soweta (SA) 35 B2 26 S 28 E
(what is the grid-block reference for this place)
B2
Soweta (SA) 35 B2 26 S 28 E
(which longitude position is this place)
28 E
Lines of latitude:
Lines … a globe
around
Lines of latitude:
Also called
Parallels
Lines of latitude:
Called parallels - why
They run parallel to one another and are an equal distance from another
Lines of latitude:
Degrees of latitude are numbered from
0 to 90 N / 90 s
Lines of latitude:
0 degree line
Equator
Lines of latitude:
90 degrees north
north pole
Lines of latitude:
90 degrees south
south pole
Lines of latitude:
List the lines of latitude from the N. pole to the equator
(2)
- Arctic circle - 66,5 N
- Tropic of Cancer - 23,5 N
Lines of latitude:
List the lines of latitude from the equator down
(2)
- Tropic of Capricorn - 23,5 S
- Antarctic circle - 66,5 S
Lines of longitude:
Lines … a globe
over
Lines of longitude:
Also called
Meridians
Lines of longitude:
These lines run
up and down a globe
(from north to south poles)
Lines of longitude:
Degrees of logitude are spread out around the globe from
0 degrees to 180 E / W
Lines of longitude:
180 line of logitude
(both names)
Greenwich merdian / prime meridian
Lines of longitude and latitude:
How do they get their name
From the size of the angle that is formed between 0 + the centre of globe
What is a Hemisphere:
What is the shape of a globe called
sphere
What is a Hemisphere:
Half of a sphere
hemisphere
What is a Hemisphere:
How can a sphere be divided
Into 2 halves / hemispheres. It can be cut vertically and horizontally
Northern and Southern hemispheres:
Are divided by what
(look at heading)
Equator
Northern and Southern hemispheres:
How are they divided
Horizontally
Eastern and Western hemispheres:
Divided by what
Greenwich merdian / prime meridian
Eastern and Western hemispheres:
How are they divided
Vertically
Eastern and Western hemispheres:
Why is the eastern and western hemispheres divided by the 180 degree line of longitude?
They chose 1 vertical line
- it has one line that faces us
- one that doesn’t
- they = scientists
Eastern and Western hemispheres:
The line that faces us
Greenwich Meridian (Prime) - 0 degree line
Eastern and Western hemispheres:
Line that faces away from us
180 degree line of logitude
Eastern and Western hemispheres:
Where does the ‘special’ line run from
(special - greenwich/prime meridian)
Pole to pole
Location of SA:
Located where
Hemispheres
Southern and Eastern
Latitude and logitude on a map:
What follows after every degree of latitude
North / south
Latitude and logitude on a map:
What follows after every degree of logitude
East / west
Naming points on a map:
Latitude / Longitude first when plotting
Latitude then logitude
Naming points on a map:
Why must we write N, S, W or E after the number
So we know the if it’s e/w of the greenwich and N/S of the equator
Naming points on a map:
What do we do if the place is not exactly on a line
estimate the closest answer
Consept of scale
An object that is an exact but smaller copy of the original -called a model
Model
(keeps what)
Keeps the shape of the original object
How are the cars scaled?
(there is a big car and a small car)
They are scaled down
(copies of the real objects)
What is the same about the original and the model?
They look exactly the same
Why are the model and original object the same?
Because the model is equally smaller
What do we say when a model has been reduced in size?
It has been scaled down
What do we call the number of times a model has been reduced?
The size
What can also happen to a model other than being scaled down?
It can be made larger
What do we call it when a model is made bigger?
Enlarged / scaled up
