Population Density
Revision PowerPoint
Let’s get started…
• You need to know the keywords to understand the
assessment.
• To test your knowledge, you could print the next slide.
• Draw a line in PENCIL to link the keyword to it’s meaning!
• Then check your answers using slide 5
• Using the glossary on Doddle may help.
• See presentation “Sparse and dense populations- Part 4”.
Population Revision Key word link up!
Use the notes in your exercise books and the glossary on page 126-127 in the the geog
1 AND geog 2 book to link the keyword to it’s meaning!
Population Density
The number of people in a place
Sparsely populated
Things we need to live and work
e.g. food, fuel
Densely populated
The average number of people per
square km in a place
Population
Very few people live there.
Resources
Lots of people live there.
Site
Settlement
A place where people live- a hamlet,
village, town or city.
Land a settlement is built on.
Now check your answers….
Correct any mistakes. Make sure you learn all the keywords ready
for your assessment!

Look at the next six pictures
• Where do you think each one is?
• What is the population density like?
Sparse or Dense?
• Why do you think this is?
• Click to reveal the answers!
Picture 1
Where? Antartica
Density? Sparse
Why?
Too Cold and no soil to grow crops.
Covered in snow and ice. Too Cold for people.
Snow and ice make communications and settlement difficult.
Picture 2
Where? The Amazon basin
Density? Sparse
Why?
Too Hot and Wet for people, Dense forest makes travelling
(communication) and Building settlements difficult
Picture 3
Density? Sparse
Where? Sahara Desert
Why?
Too Hot and Dry for people. Too dry and too little soil for crops to
grow. Sand makes communications difficult.
Picture 4
Where? Bangladesh
Why?
Density? Dense
Low lying and flat (No steep slopes!). Rich, fertile soils. Hot and
wet. Ideal farming conditions!
Picture 5
Where? Himalayas
Density? Sparse
Why?
Cold temperatures in Winter.
Poor, thin soils and rocks makes farming difficult.
Steep slopes make communications and settlement difficult.
Picture 6
Where? Western Europe
Why?
Density? Dense
Low lying and gentle slopes. Pleasant climate for people. Good
water supply and soil for farming. Many resources for industry!
Now you are going revise
population density and
explain why some parts of
the world are sparsely
populated and some are
densely populated.
We have looked at six regions and
summarised the information on our
revision sheets.
• Be ready to:
• Locate each region.
• Describe it’s population Density as sparse or Dense.
• Give reasons why it is like that.
• Have a go at filling in the gaps on a print out of slide 14.
Then check your knowledge using slide 15

Example Region: Sahara Desert
Factors that effect Population density:
Too hot and dry for people. Too dry and
too little soil for crops. Sand makes

Factors that effect Population
density:
Low-lying and gently sloping.
Too cold for people
Pleasant Climate
Steep slopes are bad for
communications and settlement.
Good water supply and good
soil for farming. Easy
communications and many
