"Australia" PPT

Part One: World Living Fossil Museum

Located in the Southern Hemisphere, between the Pacific and Indian Oceans, with the Tropic of Capricorn crossing the center, it is the only country in the world that occupies a single continent.

On the national emblem of Australia, there are two animals unique to Australia. Do you know their names? They are the famous long jumpers of the animal kingdom - kangaroos and huge emus. Australia also has many unique creatures, such as the platypus, which is good at swimming, and the cute and honest koala. (Figure 8.35 Australia’s position in the world)

Australia's endemic organisms are ancient biological species preserved during the evolution of the earth. Although they seem a bit primitive today, they have become living fossils for humans to study the evolution of the earth.

Australian PPT, Part 2: Classroom Activities

1. Why are there so many ancient creatures only in Australia? Let’s explain it using the theory of continental drift.

(1) Approximately when did the Australian continent separate from other continents?

(2) The Australian continent has existed alone on the oceans of the Southern Hemisphere for a long time. What impact will this have on biological evolution?

(3) In fact, the continents that have been isolated for a long time are not only the Australian continent, but also the Antarctic continent. Why are there so many unique creatures on the Australian continent, but so few on the Antarctic continent?

2. Australia is known as the "World Living Fossil Museum". Read the following materials to understand the meaning of "The World Living Fossil Museum".

According to statistics, Australia has 12,000 species of plants, 9,000 of which are not found on other continents, accounting for 75% of the total number of plants; there are 650 species of birds, 450 of which are endemic, accounting for 69% of the total number of birds. There are 150 species of marsupials in the world, but only a few in South America. Most are in Australia.

Australia PPT, Part 3: A country “riding on the back of a sheep”

If you often visit the supermarket, you may find that some wool sweaters have the words "100% Australian wool" on their labels. Do you know what this means? This means that these sweaters are all made of wool imported from Australia. Australia is the country with the largest number of sheep and exports of wool in the world. Because there are so many sheep, Australia is known as a country that "rides on a sheep's back".

Australia takes advantage of the natural conditions of different regions and develops agriculture according to local conditions, forming four different agricultural and pastoral areas (Figure 8.37).

Australia is a sparsely populated country with a vast territory. The average population density is only 2.5 people/km², which is about 1/45 of China. Farms are very large, generally reaching several thousand hectares. With so few people managing such a large farm, agricultural production needs to be mechanized. Australian agricultural production is highly mechanized and adopts advanced production technology, which consumes very little labor. Most of the main agricultural products are exported. In addition to wool, Australia is also an important exporter of beef and wheat in the world. Agriculture and animal husbandry have always played an important role in Australia's economy.

Australia PPT, Part 4: A country “sitting on a mine cart”

Australia is a country rich in minerals. On the basis of abundant mineral resources, Australia's mining, metallurgical and machinery manufacturing industries developed rapidly after World War II and have now become pillar industries of the national economy. More than half of the ore mined in Australia is exported, making it one of the world's leading exporters of mineral products. Since mineral product exports account for a large proportion of total exports, some people say that Australia is a country "sitting on a mine cart".

Since the 1970s, Australia's service industry has developed rapidly. At present, the service industry has greatly surpassed agriculture, animal husbandry, industry and mining, and has become Australia's leading industry.

Australia's population and cities are mainly distributed in the southeastern coastal areas. The capital, Canberra, is a planned city with a beautiful environment. Sydney is the country's largest industrial center and port city. Melbourne is the second largest city in the country.
