Where on Earth are you?
This is Earth. It looks small in
this picture,but it's really,
Imagine that you were lost
somewhere on Earth and you needed
to tell someone how to find you.
How would you do it?
Chek out this video.
After you learn how Latitude and Longitude works, you will be able tell
someone your exact location on planet Earth. Amazing, right?
Watch this video to learn more!
Another easy way to remember
the difference between latitude
and longitude is to use the word

If you think that a tall person is long, you know that they are long up and down, not from side to side. This helps to remember that longitude goes up and down.
Here are some ways to remember
the difference between latitude and longitude.

Latitude is

When you think about latitude lines, think about them lying down flat. They start at the middle of the Earth (called the equator or zero degrees latitude).
Just like latitude, there is also a line
of zero degrees longitude. It's called
the Prime Meridian and it runs through
Greenwich, England. Would you like to
know why?
Follow the link below to learn more
about the Prime Meridian!
So how do they work together to pinpoint a location on the Earth?
They form a grid, like this one:
Notice the way that latitude and longitude lines cross?
These are lines of latitude.
These are lines of longitude.
They are always measured by degrees North or South, depending on how far they are away from and what direction they are from the equator.
This is the key to finding any location on Earth.
Let's find out!
Let's say that you were at an art gallery somewhere in the world. You see a sign that says this:
By entering your latitude and longitude into a mapping website such as google maps, I found you in Austin, Texas. You are on this street that you see here! Amazing, right?
Now that we know where you are, let's see if you can do this exercise.
Using your new skills, find the cities that match the latitude and longitudes below the map.
You are at 30.2669 degrees North, 97.748 degrees West.
The sign that you see in front of you says:
You are at 30.2669 degrees North, 97.748 degrees West.
Using what you have just learned about latitude and longitude, you should now understand that you are at the point where the 30th line of latitude north of the equator and the 98th line of longitude west of the Prime Meridian cross each other.
So where on Earth are you?
You should be proud of
yourself. You now have the
tools to find any point on this
great big planet!
