20 lines about australia continent​

Answer 1

Answer:

The continent of Australia is sometimes defined as including mainland Australia and its surrounding islands including Tasmania, making it the world's smallest continent.[1][2] When this definition is used, Australia is the world's only continent that is governed by a single nation state, Australia.[3][4]

When defined as only Australia, the continent is approximately 7,690,000 square kilometres (2,970,000 sq mi) in size.[1] It is the world's lowest lying continent, its highest point is Mount Kosciuszko with an elevation of 2,228 metres (7,310 ft), the lowest point is Lake Eyre which is 15 metres (49 ft) below sea level, and the continent’s average elevation is 330 metres (1,080 ft).[2]

Australia and New Guinea Edit

The continent of Australia is also sometimes defined as encompassing a larger area, being the Australian mainland, Tasmania and the island of New Guinea, all of which share a shallow continental shelf.[5] This definition encompasses all of the modern landmasses that at times of lower sea levels were encompassed in the prehistoric continent referred to as Sahul.[6] With the inclusion of New Guinea, the continent is governed by three nation states: Australia, Papua New Guinea, and Indonesia (which governs Western New Guinea).[7]

Under this definition New Guinea represents a mountainous northern margin of the Australian continent, as New Guinea is one of the most mountainous islands in the world.[7] The highest point in New Guinea is Puncak Jaya with an elevation of 4,884 metres (16,024 ft).[8] The combined area of Australia, New Guinea and Tasmania is approximately 8,500,000 square kilometres (3,300,000 sq mi).[9]

Under both definitions the continent of Australia is the Earth's only continent that lies entirely within the Southern Hemisphere that is not covered by ice.[5]
