Physical Geography

2. Australia

3. Size Doesn't Matter
Australia is the smallest continent in terms of total land area.
Most of the landmass is actually under water

4. Oceania A region centered on the islands of the tropical Pacific Ocean
Oceania is dominated by the nation of Australia then New Zealand, and the western half of New Guinea

5. Continental Islands
Australia, New Zealand, and New Guinea are continental islands.
Continental islands were once attached to continents before sea level changes and tectonic activity isolated them.

6. High Islands Created as volcanic eruptions build up land over time.
eruptions begin under water, when hot magma is cooled and hardened by the ocean.
Over time, this activity creates islands with a steep central peak

7. Low Islands
They are made of the skeletons and living bodies of small marine animals called corals.
Sometimes, they barely reach above sea level
often take the shape of an irregular ring of very small islands surrounding a lagoon.
