Extreme Climates Revision
What are the
challenges of
extreme
climates?
How can
extreme
environments be
managed and
protected from
the threats they
face?
Key ideas
Detailed content
Extreme climates are
located in polar regions and
hot arid areas; each has key
physical characteristics.
Investigating the climate of one named extreme environment:
The Australian Outback
People adapt to the
challenges of extreme
climates in a variety of
ways.
Investigating the adaptations people make in the Australian
Outback, such as farming methods, building styles, clothing,
transport, energy use
Extreme climates are under
threat from a range of
processes, which include
climate change.
Investigating the threats to people and natural systems in the
Australian Outback, such as cultural dilution through tourism,
pollution through resource exploitation, and land degradation
through poor land management.
Examining how flora and fauna are successfully adapted to the
hot and dry conditions of the Australian Outback, but are also
vulnerable to change.
Considering the uniqueness and value of the culture of the
Australian Aborigines who live in the Outback.
Investigating how climate change could threaten people and
natural systems, such as desertification or species migration,
in the Australian Outback.
Sustainable management is
needed locally and globally,
if extreme environments are
to survive.
Assessing a range of local actions such as planting salttolerant crops and making land-management agreements with
Aboriginal population.
Assessing the role of global actions to protect extreme
environments like the Australian Outback from the threat of
climate change (Kyoto, World Heritage Sites, Ramsar status)
The Outback
• Describe the
climate of the
Outback (2)
• Explain why the
climate is like
this (2)
Why is it hot and dry?
• Rain shadow area – prevailing winds blow from
Pacific, rain falls on mountains of the Great Dividing
range.
• Deserts found 30°N and 30°S – descending air, so no
clouds form
How have these plants and animals
adapted?
• For either A or B, give one reason for the shape of the roof (1)
• For A or B, describe how it is adapted to the climate (2)
• What else could be done to house A?
Life & Culture
Aborigines
Threats
Can you talk about these threats to the
outback?
• Over extraction of water
• Poor land management
– Soil erosion
– Salinity
• Climate change
– Desertification
– Bush fires
• Cultural erosion
Explain how these are helping to ensure
the survival of the Outback
– Kyoto
– World Heritage Sites
– Ramsar Convention
– Reducing Australia’s population
– National Native Title Tibunal
– Looking After Country Together
– Salt-tolerant planting
Exam Questioin
• Using named examples, explain how local and
global actions are helping to ensure the
survival of either extreme cold or hot arid
environments (6)
• You will be marked on QWC for this Q
• You should use local and global examples
