3. Latitude
Latitude lines are the angular
distances measured north
and south of the Equator .
Latitude lines are also know
as Parallels.
The lines become
progressively shorter as
ones moves toward the
North or South Pole.
The 60 degree latitude lines
is very useful for quickly
assessing are distortions on
maps. It is also on-half the
length of the equator.
There are 60 minutes of
latitude between every
degree and 60 seconds of
latitude between every
minute.

4. Equator
The Equator is the longest
Latitude line, it divides the
Earth into a north half and a
south half.
Therefore it is located
halfway between the North
Rotational Pole and The
South Rotational Pole.
The Latitude of the Equator
is 0 degrees because you
measure distances North and
South of it.
The Equator is 25, miles
long.

9. Longitude
Longitude lines are the
angular distances
measured east and west of
the Prime Meridian.
These lines only go half
way around the Earth,
forming half-circles.
Longitude lines are also
known as meridians.
They being and end at a
rational pole and are
roughly the same length.

10. Prime Meridian and
International Date Line
The Prime Meridian is the
zero (0) degree longitude
line because angular
distances are measured east
and west of it.
It begins at the North Pole
and runs through the Royal
Observatory in Greenwich,
England and continues all
the way to the South Pole.
The Prime Meridian goes
half way around the earth.
The International Date Line is also
the 180 degree longitude line.
Which is the highest numbered
longitude line.
It is located opposite the Prime
Meridian.
It is called the International Date
Line because when you travel west
of it you add a day and when you
travel east of it you subtract a day.
But the International Date Line is
not directly on the 180 degree
longitude line; it zigzags through
the Pacific Ocean to avoid
splitting countries and island
group.

18. Conclusion
In conclusion the Earth’s Grid is the network of parallels
and meridians super imposed on Earth’s surface used to
locate features.
I have never done a presentation like this and it was very
eye opening. The presentation can go where ever you
want it to. I don’t have to click and click to get back to a
particular slide. I like that I can click backwards as well. I
also liked all the animation features, it really spices up the
presentation.
