Q & A
What is the main focus of the video script?
-The main focus of the video script is to introduce and discuss the importance of maps in AP Human Geography, including different types of maps, their strengths and weaknesses, and how to analyze them.
What are the two main types of maps mentioned in the script?
-The two main types of maps mentioned are thematic maps, which focus on one theme and use data to illustrate patterns and spatial connections, and reference maps, which are used for navigation and do not present a specific theme.
Why is it important to identify the strengths and weaknesses of a map?
-It is important to identify the strengths and weaknesses of a map to ensure accurate analysis and to avoid drawing incorrect conclusions from the data presented.
What is a chloroplast map and why is it significant in geography?
-The term 'chloroplast map' seems to be a mistake in the script. It might be a mispronunciation or confusion with 'choropleth map', which is a type of thematic map that uses color to represent data variables for different areas.
How can maps be used to understand complex issues?
-Maps can be used to visualize data and trends, allowing for the identification of patterns and spatial relationships that can help in understanding complex issues such as birth rates, poverty, education, and trade with other countries.
What is the difference between absolute distance and relative distance on a map?
-Absolute distance deals with quantitative terms, such as miles or kilometers, indicating the exact distance between two points. Relative distance, on the other hand, deals with qualitative terms like time taken to travel or direction using a compass rose.
What is distortion and why is it a concern when using maps?
-Distortion refers to the inaccuracies that occur when representing a three-dimensional globe on a two-dimensional surface. It can affect direction, distance, shape, and area, and is a concern because it can misrepresent the true nature of geographic features.
Why might the size of Greenland appear larger than Africa on a Mercator map?
-The Mercator map projection distorts the size of areas towards the poles, making Greenland appear larger than Africa, despite Africa being significantly larger in reality.
What is the importance of scale in thematic maps?
-Scale is crucial in thematic maps as it determines the level of detail and accuracy of the data presented. A small scale map may generalize data, while a large scale map can show more detailed and accurate information.
What are some aspects to consider when analyzing a map?
-When analyzing a map, consider the title, legend, shadings, colors, symbols, compass rose, scale, and the relationship between items on the map and the earth's surface to understand what the map is showing.
What is the purpose of the review questions at the end of the video script?
-The review questions serve as a pop quiz to check the viewer's understanding of the main components discussed in the video and to reinforce the learning experience.

Transcripts
hey there everybody and welcome back to
a new school year on the mr sin channel
today we start our journey of ap human
geography and
it's going to be quite a ride throughout
the school year we're going to be
covering
every single topic that you need to know
in order to do well in your class and
also on the ap test in may
so without further ado let's start
learning about topic 1.1 where we're
going to be talking about what else
maps now there is a bunch of different
maps out there and each map we look at
throughout this course is going to be
presenting us with different types of
information
and each map has different strengths and
weaknesses it's really important that we
can identify
these different strengths and weaknesses
when viewing a map because we're going
to have to be
analyzing maps in order to make
conclusions and to be able to understand
different spatial relationships
throughout this whole year some maps use
data
to help illustrate different patterns
and spatial connections within a
geographic area
maps like a chloroplast map or a flow
line map or a cartogram or graduated
symbol map
each of these maps are trying to present
the reader with a certain topic hence
why it's a thematic map
it's focused around one theme we also
have reference maps that do a great job
at getting us from point a
to point b these maps aren't using data
they're great for us to better
understand what's happening on the
earth's surface there's no
theme that's being presented here we're
just viewing a geographic area
regardless of what map you're using
there's no doubt that maps are powerful
tools and geographers use maps
all the time now maps can be used for
something as simple as going from my
house to chipotle
or they could be used to better
understand different types of elevation
if i'm looking at a topographical map
but we could also use them to understand
birth rates and poverty and education
cancer rates how we trade with other
countries
in order to really show you exactly what
i'm talking about i'm going to count to
five
while i'm doing this i want you to view
the maps on the screen right now and try
to see if you notice anything about
these maps
okay time's up now there's a youtube
video if you need more time just pause
it
but did you start to see some
connections did you notice that a lot of
the countries that have the highest
growth rate
also unfortunately have a lot of kids
dying and they also have high rates of
poverty
that could be something that's worth
exploring maybe there's a connection
between
a high nir a high growth rate and high
amounts of poverty and
unfortunately child mortality these are
concepts we're going to be exploring
and maps can visualize that now that we
can see some of the ways that maps can
present us data and trends and be used
we also have to go over a couple of
their aspects that you should be on the
lookout for when you're analyzing a map
first one to know is the difference
between absolute distance and relative
distance
now absolute distance is dealing in
quantitative terms
while relative distance is actually
dealing in qualitative terms when you're
looking at a map if you're trying to
understand how far away something is in
terms of miles or kilometers
that's absolute distance while relative
distance is going to be looking
at time how long does it take us to get
somewhere or what direction are we going
using that compass rose you'll also
notice that items on maps can be
clustered or dispersed
all that means is if it's clustered
things are really packed together
there's not a lot of space in between
different items
on the other hand if they're dispersed
there's a lot of space between them now
the one thing you really need to look
out for when you're using a map
is distortion every map struggles with
this it might be in the direction
the distance the shape or even just the
area
distortion impacts maps because it's
hard to take a globe and put it onto a
flat surface
so each map has to make certain
compromises now oftentimes when they do
that they'll end up minimizing the
distortion in one area but then they'll
increase the distortion in another
or they'll make the map more difficult
to read or maybe they're going to cut
off just parts of the earth in general
in order to try and remove it
so different cartographers have used
different techniques in order to try and
make the most accurate map for example
when looking at the mercator
map what do you notice about greenland
and what do you notice about africa
if you didn't know this one's greenland
and this one's africa if we're just to
brace our answer off the mercator map
you're gonna probably come to the
conclusion that greenland is
significantly larger than africa
and that could not be further from the
truth africa
is way larger than greenland look at all
the countries you can actually fit
inside of africa
greenland is tiny but distortion here
distorts the truth
and so we have to always be cognizant of
that hey
sorry for interrupting the flow of the
video but i do have to highlight that
there's a bunch of map projections that
you need to know about
i just mentioned the mercator map
projection and earlier in this video i
talked about different thematic maps as
well
all of these are important for you to be
able to read and understand and you also
have to know the different strengths and
weaknesses of
each of these maps and when filming this
it just didn't work for me to put
all of that into this one video now in
future videos when we go into the
different topics of ap human geography
i'm going to always try to make sure it
all fits in one video but for this one
it just didn't work
so i have two other videos that'll
actually talk about the thematic maps
and the other map projections
specifically
i really recommend you check that out
because you're going to need that
information as well
all right sorry for the little high note
here let's get back and look at
distortion with thematic maps so clearly
reference maps have some issues with
distortion and thematic maps also do as
well
when we're creating thematic maps
geographers and cartographers
have to make decisions what ranges
should i use to present my data
is there movement how am i going to
visualize that movement what happens to
a region on the map that doesn't have
any data
all these different things impact how we
view the data and the map
and that can lead us to actually come to
conclusions that might not be true for
example take five seconds and look at
this map that's showing world religions
what do you notice
five four three
two one and that's time maybe you notice
that
for the most of the world there's
actually only one or two religions
christianity looks like to be the only
religion in many parts of the world
and here distortion is actually
connected to the scale we're looking at
a small scale map right now
and this is actually having
generalizations occur we're not being
able to see a clear picture
if we were to change the scale from a
global scale down to
let's say a large scale map which would
be more showing a local community
we can actually see that there are tons
of different religions
and what we looked at originally turned
out to be wrong
at first we thought it was just one main
religion however as we
zoomed in we now start to see that there
is a large variety of people
and here again distortion has made it so
we're not getting a clear picture of the
map whenever you're looking at a map
whether it's a reference map or a
thematic map
always try and think what's the map
trying to tell me what is the map trying
to say
look at the title look at the legend
look at the different shadings and the
colors the symbols that compass
rose the scale the relationship between
items on the map
and the earth's surface all of these
things will help you understand exactly
what the map is showing you and when we
do this
you will be amazed at how you can
visualize the world and how you'll be
able to break down
complex issues right in front of you hey
you did it first official video down
now you might notice right now that
there's some review questions on the
screen
fear not it's not a trick quiz i mean it
kind of is a pop quiz since you didn't
see it coming
but this is a way to check to see did
you understand some of the main
components of this video
i'm going to try to do this in most of
our videos they're just a couple
questions and this way you can see if
you're really getting the information
once you think you got the answers go
down to the comment section and see if
you got them right
also don't forget to subscribe more
videos are coming that are going to help
you succeed in ap human geography
and if you're struggling with ap human
geography check out my ultimate review
packet it's a
great tool to help you study for your
class and also get a five on that
national exam
all right thanks so much geographers for
watching i'm mr sin and until next time
i'll see you
online i almost forgot don't forget to
watch the video on map projections and
the different thematic maps you need
that information again i'm gonna try not
to do that in future videos
okay that's all i got for today have a
great day geographers
you
