Choo choo choo choo choo longitude and latitude
In order to locate quickly
The two lines are intertwined and classified
Latitude is the number of degrees marked on the parallel
Zero latitude at the equator means the starting point
So the unification north of the equator is north latitude
In the same way everything south is called south latitude
Latitude is divided into three areas
Every 30 degrees
That is low medium and high latitudes
This is an international standard
N is used to indicate north latitude
The same is true in south
It's just that the degree is ahead
The symbol follows
Longitude and latitude
In order to locate quickly
The two lines are intertwined and classified
Can be understood as coordinates
Overlapping of two levels
Formed a relatively simple auxiliary factor
The latitude narrows from the equator to the poles
So the equator is the boundary between the northern and southern hemispheres
And it indicates both east and west directions
The north and south poles are points
Connecting the north and south poles
And perpendicular to each other
Known as the meridian
All are equal
In order to distinguish each meridian
Are marked with different degrees
It's the same principle as the parallel
But this is called longitude
Zero meridian is also called
First or prime meridian
Located at Greenwich Observatory
As a starting point
Meridians of zero and one hundred and eighty degrees
It is common in east longitude and west longitude
Longitude and latitude
In order to locate quickly
The two lines are intertwined and classified
Can be understood as coordinates
Overlapping of two levels
Formed a relatively simple auxiliary factor
The division of the eastern and western hemispheres
Use 20 degrees west longitude and 160 degrees east longitude
Because it basically passes through the ocean
Also avoid separating some countries
Longitude and latitude
In order to locate quickly
The two lines are intertwined and classified
Can be understood as coordinates
Overlapping of two levels
Formed a relatively simple auxiliary factor
