Australia

Essential Questions

How have Australia’s location, climate, and natural resources affected where people live?

How have Australia’s location, climate, and natural resources impacted trade?

Key Terms

Marsupial- an animal that carries its young in a body pouch

Coral- a rocklike material made up of the skeletons of tiny sea creatures

Geyser – A hot spring that ejects a column of water into the air.

Tectonic plate- a large piece of the Earth’s crust

Location! Location! Location!

What does the location mean?

Located in Southern hemisphere (south of the Equator): seasons opposite of those in the U.S.

Located in the Eastern hemisphere

Far from large landmasses So what does this mean?

Unique Environment

Plants & Animals unique to the region.

Biologically unique- Marsupials (Almost all mammals are marsupials in Australia)

Kiwi & Yellow-eyed Penguin

Kiwi?? No, not quite

That’s more like it!

Marsupials

Why So Unique??

Tectonic Plates: Australia & Oceania are part of the

Indo-Australia plate. Once part of large landmass that

included Antarctica. Moved NW in Pacific Ocean

Wild life slowly changed, b/c islands are isolated these living things did not spread to other regions

Where do people live in Australia?

Most Australians live along Australia’s E & SE coasts This plain has most

fertile farmland & receives ample rain

Moist winds from the PO bring rain & mild pleasant climate

Presence of the Murray & Darling rivers

Great Dividing Range

W of GDR is rain shadow.

People depend on wells for fresh water

Outback: desert & grassland

Environmental Concerns

1. RunoffSeveral major cities along NE coast. Large areas of coastal lands have been used for

agricultural & pastoral purposes. Sediment & chemical runoff from farming Loss of coastal wetlands which are natural filter Results in 400 of 2600 reefs are within risk zone were

water quality has declined Crown-of-Thorns starfish natural predator of

corals, dramatic increase in species caused by decreased water quality

Crown-of-Thorns Starfish

Environmental Concerns cont. . .

Global Warming

Many corals living at upper edge of temp. tolerance.

This can lead to Coral Bleaching Corals release photosynthesizing cells- turn white If water doesn’t cool down w/in a month, coral dies

Also brings about more violent tropical storms
