Chapter 30
Physical Geography of Southeast
Asia, Oceania, & Antarctica
A Region of Extremes
Objective: Identify key
features of physical
geography, climate, &
vegetation, & humanenvironment interaction in
Southeast Asia, Oceania, &
Antarctica
Chapter 30 Section 1
Landforms & Resources
Vocabulary: Archipelago, Oceania,
High Island, Low Island, & Great
Barrier Reef
Objective: Describe key landforms
& resources of Southeast Asia.
Southeast Asia: Mainland & Islands
• Southeast Asia has two subregions: the mainland &
islands
• The Indochinese peninsula
serves as a bridge between the
mainland & islands
• Archipelago: closely
grouped islands
• Fertile soil is a valuable resource
in Southeast Asia
• Southeast Asians also have
access to other mineral resources
Lands of the Pacific & Antarctica
• Geographers estimate 20,000
islands in the Pacific Ocean
• Oceania: group of islands in
the Pacific, including
Melanesia, Micronesia, &
Polynesia
• Philippines & Indonesia are not
considered part of Oceania because
of the cultural ties to Asia
• High Islands: created by
volcanoes
• Low Islands: created by coral reef
• Great Barrier Reef: 1250 mile
chain of reefs & islands
containing 400 species of coral
Chapter 30 Section 2
Climate & Vegetation
Vocabulary: Outback
Objective: Examine the climates of
Southeast Asia, Australia, & New
Zealand
Widespread Tropics
• Tropical weather is found
in coastal plains of
Myanmar, Thailand,
Vietnam, & Oceania
• Their average annual
temperature is around 80
degrees
• Monsoons shape the weather
in the northern or inland
regions
• Southeast Asia has one of
the greatest diversities of
vegetation of any region
Bands of Moderate Climate
• Australia is split between
two climate zones (hot
summers/mild winters &
mild summers/cool
winters)
• Northern Australia receives hot
summers, mild winters, & heavy
rainfall
• New Zealand & Southern
Australia have a marine west
coast climate
• The coast of Australia is the
most heavily populated
region
Hot & Cold Deserts
• 1/3rd of Australia is
desert
• Crops can only be grown
there using irrigation
• Outback: dry,
unpopulated inland
region of Australia
• The few people that live
there get medical care from
the Royal Flying Doctor
Service
Chapter 30 Section 3
Human-Environment Interaction
Vocabulary: Voyaging Canoe,
Outrigger Canoe, Atoll, & Bikini
Atoll
Objective: Explain how ancient
islanders traveled the Pacific
Traveling the Pacific
• Pacific Islands most likely
came from Southeast Asia
• They ventured farther out into
the Pacific using the stars &
charts for navigation
• Voyaging Canoes: large
ship developed by Pacific
Islanders to sail the ocean
• Outrigger Canoe: a small ship
used in the lagoons of islands
where Pacific Islanders settled
Invasion of the Rabbits
• Europeans brought with them
to the Pacific Islands, familiar
animals such as rabbits
• In 1859, they released 24
rabbits to hunt
• By 1900, Australia had more
than a billion rabbits
• Rabbits have destroyed
farming in Australia
• They have a combination of
methods to try to reduce
the number of rabbits
Nuclear Testing
• Atoll: ring-link coral island or
string of small islands around a
lagoon
• Bikini Atoll: site of US atomic
weapons tests
• The government moved the 167
islands to another Atoll
• The testing vaporized several
islands & contaminated the
entire region
• The government allowed them to
move back but found radiation in
the islanders bodies and moved
them off the islands again
