Artesian Wells
answer
Wells from which pressurized water flows to the surface. It is too salty for humans or crops; however, ranchers use it to water livestock.
question
Coral

Limestone skeletons of a tiny sea animal.
question
Note: 10% of Australia's land can be farmed.
answer
Note: Australian farmers make effective use of their land and water to grow wheat. barley, fruit, and sugarcane.
question
Note: Australia includes 1/4 (one-fourth) of the world's bauxite. Also, it has most of the world's high-quality opals.
answer
Note: Oceania was created by colliding tectonic plates millions of years ago, the islands are part of the Ring of Fire, volcanic and earthquake activity.
question
Oceania's islands are classified into 3 clusters, based on location, how the islands formed, and the inhabitants' cultures. What are those 3 clusters and describe them.
answer
Melanesia ("black islands") lies north and east of Australia. Micronesia ("little islands") extend north of Melanesia. Polynesia ("many islands") spans an area larger than both of those clusters (Micronesia and Melanesia).
question
Name the 3 island types of Oceania.
answer
High islands-Tahiti and many islands of Fiji, feature mountain ranges split by valleys that fan out into coastal plains. Volcanic oil on high islands supports some agriculture. Low Islands-Volcanoes shaped many low islands. Low Islands-many of Marshall Islands in Micronesia, ring shaped islands, known as atolls-formed by the buildup of coral reefs on the rim of submerged volcanoes. Atolls encircle lagoons-shallow pools of clear water-and rise a few feet above sea level. Low islands-little soil and few natural resources. Continental Islands-formed by the rising and folding of ancient rock from the ocean floor. Most of Oceania's large islands such as New Guinea and New Caledonia. Volcanoes didn't create these islands. Coastal areas-plains, swamps, and rivers. *Have most of Oceania's mineral deposits.
question
New Zealand's two largest islands are?
answer
North and South Island.
question
Note: Mount Ruapehu, which is North Island's highest points.
answer
Note: Shiny freshwater lakes-Lake Taupo, New Zealand's largest lake.
question
Who were New Zealand's earliest inhabitants?
answer
Maori, who named the highest peak on South Island *Aorangi means "cloud piercer."
question
Note: Aorangi is known as Mt. Cook.
answer
Note: Lowlands called the Canterbury Plains lie on the eastern coast. This land is New Zealand's flattest and most fertile area.
question
What is New Zealand's most important resource?
answer
Its fertile soil greatly benefits the country's economy.
question
Note: 55% if the land supports crops and livestock.
answer
Note: New Zealand's sheep and wool products dominate exports, and its forests yield valuable timber. The country's rivers and dams produce abundant hydroelectric power.
question
How is Geothermal energy formed?
answer
Geothermal energy is provided by water heated underground by volcanoes.
question
Note: Fish in the warmer tropical currents-Tuna, marlin, and sharks. On the other hand, fish in the cold Antarctica currents have cod and hake.
answer
Note: Antarctica lies beneath a massive ice cap. *Covers 98%.
question
What is krill?
answer
Shrimp-like animal eaten by some whales.
question
What group of people would be most affected if Australia's artesian wells dried up? Why?
answer
Ranchers-it is because it is too salty for humans or crops; however, ranchers use it to water livestock.
question
Identify similarities and differences between New Zealand's two main islands and a high island such as Tahiti.
answer
They are both islands with high islands, such as mountains, coastal plains, and active volcanoes. They are different because New Zealand's islands are larger and support more people.
question
To which island does Papua New Guinea belong to?
answer
Melanesia.
question
Note: Subtropical high-pressure air masses block moisture-laden Pacific Ocean winds from reaching the Western Plateau, Australia's large interior desert area.
answer
Note: An area of milder steppe climate encircles Australia's desert region. Here, regular rainfall brings vegetation such as eucalyptus and acacia trees and small shrubs to life. Saplings of acacia tree were used to make wattle-a strong, interwoven wooden framework used for building homes.
question
Note: Rain only falls during the wet season. *Annual rainfall ranges from 10 to 20 inches, so short grasses, ideal fro grazing, also grow here.
answer
Note: Australia's coastal areas have a variety of moister climates. *supports most of Australia's agriculture.
question
Note: Because much of Oceania lies between the Equator and the Tropic of Capricorn, most islands have a tropical rain forest climate.
answer
Note: Pacific ocean winds cool atolls and the windward sides of higher islands.
question
Note: Oceania's dry season features cloudless blue skies often seen in travel advertisements, but the wet season brings constant rain and high humidity.
answer
Note: Low islands get little rainfall, but larger landmasses of high islands give off warm, moisture-laden air. When the air rises and mixes with cool ocean breezes, heavy rains fall.
question
Note: Shrubs and grasses grow on dry, low islands, but coconut palms and other trees appear on islands with more rainfall.
answer
Note: North Islands central plateau is warm and sunny during the summer, but mountain tops may have now year-round.
question
Doldrums
answer
A generally windless area, which occupies a narrow band near the Equator where opposing ocean currents meet.
question
Typhoons
answer
Violent storms that form over Pacific waters.
question
What climate is found in most of New Zealand?
answer
A marine west coast climate.
question
Note: Ocean winds warm the land in winter and cool it in summer, preventing temperature extremes.
answer
Note: New Zealand's geographic isolation gives rise to unique plant life. Almost 90% of the country's indigenous plants are native only to New Zealand.
question
Manuka
answer
A small shrub that grows in New Zealand, which carpets land where prehistoric volcano eruptions destroyed ancient forests.
question
Note: Antarctica is the earth's highest, driest, windiest, and coldest continent. Air loses moisture as it rises over Antarctica's plateau, making the plateau drier than Australia's deserts, but much colder.
answer
Note: In rocky areas along the coasts, tiny sturdy plants called lichens thrive.
question
Note: The Antarctic Peninsula lies in a tundra climate zone. Antarctica's ice is not motionless, even though it is frozen. The cap's tremendous weight causes the frozen mass to spread toward the coasts. As it moves, the ice breaks into pieces, causing huge crevasses, or cracks.
answer
n
question
What type of climate does most of New Zealand have?
answer
Marine west coast climate. It may appeal to settlers due to the ocean winds warming the land in winter and cooling it during the summer, preventing temperature extremes.
question
What problems might researchers encounter in Antarctica, and how could these conditions be overcome?
answer
It is earth's highest, driest, windiest, and coldest continent. All I have to say is to bring some REALLY warm clothes with you.
question
How do Pacific ocean currents and winds affect the climate of Oceania? How do they affect vegetation?
answer
Pacific ocean waters cool atolls (coral island) and windward side of higher island. The warm and cold fronts meet to form heavy rain, and where there is heavy rain; there are rain forests.
question
What type of vegetation is suitable for raising livestock, and where in Australia is it found?
answer
Grasslands--it is found circling the interior deserts.
question
What formation lies just off Australia's northeastern coast?
answer
The Great Barrier Reef.
question
Name the 3 types of islands that are found in Oceania.
answer
High islands, low islands, and continental islands.
question
What is New Zealand's main natural resource?
answer
Its fertile soil.
question
List the local resources that help to meet New Zealand's energy needs.
answer
Hydroelectric power and geothermal energy.
question
What climate supports most of Australia's agricultural lands?
answer
Humid subtropical.
question
Describe the factor that prevents temperature extremes in New Zealand.
answer
Ocean winds warm land in the winter and cool it in the the summer.
question
What causes the motion of the Antarctic ice cap?
answer
The weight of the ice cap.
