Description:
There are tons of different types of maps. We practically need a map map to remember all of them. But don't worry, we've squeezed a few of the important ones into this video to make it easy on you.

If you've ever wanted to live like a pirate, there are a number of different things you could do... [Kid wearing a pirate hat]

Spend the day wearing an eye patch...
- 00:18
Walk around with a parrot on your shoulder...
- 00:20
Or say “arr” at the beginning of every sentence. [Kid holding up a sword]

day, then good news!
- 00:28
There's an easier way to feel pirate-like…
- 00:30
Yup!
- 00:30
By using a map to find nearby buried treasure! [Cross on the treasure map]
- 00:33
Or a nearby bathroom, pool, or anything else you might be looking for.
- 00:36
…hey, anything can be treasure if you try hard enough. [Guy runs out of a car]
- 00:39
Even a toilet.
- 00:40
But guess what?
- 00:41
There are tons of different maps in the world!
- 00:43
And each type of map has a bunch of different features… [Kid deciding over which map to use]
- 00:45
You'll usually find a title, which gives you a fairly good idea of what the map is trying
- 00:49
to show you, unless of course it's written in a different language…
- 00:52
…or by a bunch of liars.
- 00:54
But hey, for the purposes of this video, let's say you can actually read the map you're looking at. [Two people reading a map]
- 00:58
You'll also probably find some sort of scale bar, which shows how far apart everything [Finger pointing to the scale bar]
- 01:01
on the map is.
- 01:03
Then there's the legend – and no, it's not some fantastical story written out on the [Guy dressed in armour with a sword]
- 01:07
map about people with magic flying shoes or snakes for hair.
- 01:10
A legend is there to explain what all the different symbols and colors on the map mean. [Symbols appear on the map]
- 01:15
And there's almost always a compass rose, which shows the four main directions: north,
- 01:18
south, east, and west.
- 01:20
Pretty straightforward stuff, right? [Each direction is shown on the compass rose]
- 01:21
Okay, on to the map types.
- 01:23
First up: the physical map.
- 01:24
A physical map is called that because it shows, well, physical features of the land.
- 01:28
What a surprise, right?
- 01:30
Some physical features you might find shown on a physical map include mountains, bodies [Examples of the features are shown on the map]
- 01:34
of water like lakes and rivers, and elevation differences indicated by various colors to
- 01:38
show things like valleys and hills.
- 01:40
Typically speaking, green will mean lower elevations while brown means higher. [Different elevation portions of the map are shown]
- 01:45
Okay, so if a physical map shows physical features, then what do you think our next
- 01:49
map type, a topographic map, shows?
- 01:51
Topos?
- 01:52
That almost sounds right... except for the fact that a “topo” isn't exactly a real thing. [Lots of question marks appear on the map]
- 01:56
Topography is the study of the shape and features of the surface of the Earth, so a topographic
- 02:00
map aims to show exactly that.
- 02:02
How you may ask?
- 02:04
By using something called “contour lines,” which you can see pretty much all over this [Finger pointing to contour lines on the map]
- 02:07
topographic map.
- 02:09
So as you can see, a topographic map is pretty similar to a physical map, except that its
- 02:13
focus is on the very specific elevation and shape of the Earth's surface by using contour lines. [Contour lines overlaying a physical map]
- 02:18
When the contour lines are close together, the elevation is steeper – and when they're
- 02:21
further apart, it's not so steep. [Mountains are shown and then plains]
- 02:23
These are helpful when you're planning out a hiking route!
- 02:25
Sign us up for the far apart contour line trail! [Two guys climbing up a steep hill]
- 02:28
Next up is a political map.
- 02:30
And no, before you ask, you can't use it to find the president.
- 02:33
Even if you could, the Secret Service would stop you pretty fast. [Guy walking over to the president whilst looking at map]
- 02:36
The word “politics” here simply refers to the state and national boundaries of a
- 02:39
given place.
- 02:41
A map which shows all the different counties in a state, for instance, would be good example [Country names popping up all over a map]
- 02:45
of a political map.
- 02:46
And unlike the previous map types we've discussed, a political map doesn't focus on physical features.
- 02:51
It's all about boundaries.
- 02:52
Lastly we've got one of the most common maps out there. [Girl holding a map in a living room]
- 02:55
If you've ever been lost on a road trip with your family before, you just might be familiar
- 02:59
with this next map.
- 03:00
It's the granddaddy of phone GPS. [Family in a car in the middle of a woods]
- 03:03
The one your dad is probably flipping around and around in a desperate attempt to figure
- 03:06
out wherever you're supposed to go. [Driver stops to look at the map]
- 03:08
Yup, it's the good ol' fashioned road map, and its purpose is pretty obvious: to show
- 03:12
all the different roads, highways and landmarks in a given area. [Examples of the features are shown]
- 03:16
And while its main purpose is to help people get from point A to point B, it's ultimately [A route is drawn onto the map]
- 03:20
up to the reader to figure that all out.
- 03:22
Good luck, pops…
- 03:23
There are many other map types too – weather maps, climate maps, ocean floor maps, and [Pictures of the other type of maps]
- 03:28
maps for pretty much every possible thing you'd want to map.
- 03:31
If you could create your very own exciting and awesome map, what would it be? [Kid drawing his own map]
- 03:34
Maybe a map of all the nearest ice cream shops?
- 03:36
A map to the nearest movie theater or arcade?
- 03:38
Or maybe just a map to the toilet.
- 03:40
Hey, when you gotta go, you gotta get there fast. [Guy running to the toilet reading a map]
