Settlements And The Environment Flashcards
(39 cards)
What two main factors are you to consider when choosing where to live?
Climate and natural resources
What are 3 things that impacts your way of living in Canada?
Cold winters can make water pipes burst
Ice storms can knock down electrical poles causing you to loose power
You need more energy in summer to cool down you house making the electricity bill higher
How can the drought in the Amazon river affect how people live?
Rainfall has decreased since the mid-1980s
Leads to less natural flooding and more water shortages
What are the 5 Physical processes affecting settlements?
Volcanos, Landslides, earthquakes and tsunamis, dust storms, desertification
VOLCANOES:
What are the dangers of living near a volcano?
When they erupt they release lava, gas and ash that can damage settlements and cause injury or maybe even death
VOLCANOES:
Why do people live near volcanoes?
- volcanic rocks contain things like gold, silver and copper
- good for mining and agriculture
- lots of natural resources
- tourist attraction
VOLCANOES:
What are they doing to provide safety for people living near volcanoes?
Early warning systems and when dormant for a while and rumbling and venting and gas tells you that it will erupt again
EARTHQUAKES AND TSUNAMIS:
Dangers of earthquakes and tsunamis
- many earthquakes happen underwater causing tsunamis
- all coastal cities in earthquake zones are in danger
- settlements with higher population density are affected more
- places with weaker structures are hot harder by earthquakes
EARTHQUAKES AND TSUNAMIS:
Reasons of staying despite the earthquakes and tsunamis
- people might not be able to relocate
- they may not want to leave their lives
EARTHQUAKES AND TSUNAMIS:
Ways to stay safe in earthquakes and tsunamis
- scientists can predict earthquakes
- cities practice earthquake drills
- make evacuation plans
- make sure buildings are earthquake proof
Desertification definition
The gradual process of drylands turning into deserts
DESERTIFICATION:
Reasons for living in those areas
-dry lands have a semi-desert to moist climate and long growing seasons
DESERTIFICATION:
What are the affects of desertification?
- many countries are losing their dry lands to desertification
- drought worsens soil quality
- desertification affects millions of people worldwide
- it can change settlement patterns
DESERTIFICATION:
Ways to fight against desertification
- Places like Africa Dan china have planted vegetation around edges of desert
- preventing soil from eroding away
DUSTSTORMS:
Dangers of dust storms
- The dust goes high in the sky and adds to the atmosphere
- the strong dusty winds can harm buildings and humans
DUST STORMS:
Positive affect of dust storms
Dust storms can minerals and nutrients to where it is needed
LANDSLIDES:
What are the dangers of landslides?
- settlements covered by clay and silt are easily washed away
- can cause lots of destruction and injuries and even death
LANDSLIDES:
What is the reason for staying in the area?
Landslides can create areas better suited for hostile environments
LANDSLIDES:
What are they doing to help after landslides?
They are building new settlements in areas created by landslides
CASE STUDY #1:
How are the people of Saudi Arabia affected by the physical environment?
- 95% of Saudi Arabia is desert with no lakes or rivers
- today the population has grown but there isn’t enough food or water to go around
- water comes from underground and when it’s gone it’s gone
- less water in the soil leads to desertification which isn’t good for crops
CASE STUDY #1:
How are they adapting to the problem?
- settlements in the past were locating in valleys where you can find underground water
- the settlements have been kept small
CASE STUDY #1:
What is their solution?
They are going to create arable land in the desert through irrigation products to grow their crops and reduce food imports
What are the 6 ways climate change is affecting settlements?
Rising temperatures, rising sea levels, change in precipitation patterns, more extreme storms, floods, coastal erosions
RISING TEMPERATURES:
Positive affects
- extended growing season for farmers
- more settlements up north
- easier transportation in frozen places
