They all existed as a single continent called Pangea. Pangea first began to be torn apart when a three-pronged fissure grew between Africa, South America, and North America.
Early Gondwana (pre-Pangea, 550-336 mya)
Gondwana was something of a miniature supercontinent. It didn't contain all land on Earth, or even close to it, really. Nearly of Earth's modern southern hemisphere landmasses were part of Gondwana.
This giant landmass known as a supercontinent was called Pangea. The word Pangaea means "All Lands", this describes the way all the continents were joined up together. Pangea existed 240 million years ago and about 200 millions years ago it began to break apart.
Pangea, also spelled Pangaea, in early geologic time, a supercontinent that incorporated almost all the landmasses on Earth. Pangea was surrounded by a global ocean called Panthalassa, and it was fully assembled by the Early Permian Epoch (some 299 million to about 273 million years ago).
About 200 million years ago, all the continents on Earth were actually one huge "supercontinent" surrounded by one enormous ocean. This gigantic continent, called Pangaea , slowly broke apart and spread out to form the continents we know today.
The early Earth is loosely defined as Earth in its first one billion years, or gigayear (Ga, 109y). The “early Earth” encompasses approximately the first gigayear in the evolution of our planet, from its initial formation in the young Solar System at about 4.55 Ga to sometime in the Archean eon at about 3.5 Ga.
At its beginning, Earth was unrecognizable from its modern form. At first, it was extremely hot, to the point that the planet likely consisted almost entirely of molten magma. Over the course of a few hundred million years, the planet began to cool and oceans of liquid water formed.
Australia is "older" because much of it is little changed from the early days of the Earth. In places, later sediments were deposited only to be eroded away again, once again exposing the ancient land surfaces, which are again subjected to erosion.
Proterozoic Australia was part of the supercontinent of Gondwanaland, comprising India and the other southern continents, from about 750 million years ago.
From about 300-200 million years ago (late Paleozoic Era until the very late Triassic), the continent we now know as North America was contiguous with Africa, South America, and Europe. They all existed as a single continent called Pangea.
Adam is the name given in Genesis 1-5 to the first human. Beyond its use as the name of the first man, adam is also used in the Bible as a pronoun, individually as "a human" and in a collective sense as "mankind".
Roughly 10,000 years ago, Earth was experiencing a time of critical change. The planet was leaving the Ice Age, near the end of a much larger pattern of warming and cooling climate events. This led to major changes in the environments people were living in.
Approximately 300,000 years ago, the first Homo sapiens — anatomically modern humans — arose alongside our other hominid relatives.
Some 180 million years ago, in the Jurassic Period, the western half of Gondwana (Africa and South America) separated from the eastern half (Madagascar, India, Australia, and Antarctica).
About 130 million years ago Gondwana began to break up and the continents as we know them today began to drift apart. Australia began to drift northwards at the rate of about 10 cm a year (Australia still moves about 6 to 7 cm per year).
Australia was once part of a much larger land mass called Gondwana, which included the modern continents of Africa, South America, Antarctica and India.
There is no one Aboriginal word that all Aborigines use for Australia; however, today they call Australia, ""Australia"" because that is what it is called today. There are more than 250 aboriginal tribes in Australia. Most of them didn't have a word for ""Australia""; they just named places around them.
"Combine Australia!" Australia became a nation on 1 January 1901 when 6 British colonies—New South Wales, Victoria, Queensland, South Australia, Western Australia and Tasmania—united to form the Commonwealth of Australia. This process is known as Federation.
The name Australia (pronounced /əˈstreɪliə/ in Australian English) is derived from the Latin Terra Australis (“southern land”), a name used for a hypothetical continent in the Southern Hemisphere since ancient times.
Earth's oldest known piece of continental crust dates to the era of the moon's formation. Australia holds the oldest continental crust on Earth, researchers have confirmed, hills some 4.4 billion years old.
Australia completely separated from Antarctica about 30 million years ago.
North of Western Australia is the Pilbara, a sizable, arid area with a sparse population. The Pilbara area of Western Australia is home to the fossilized remains of the planet's earliest life forms. Because of the discoveries made in the area, it has been declared the oldest place on Earth.
Nobody knows when people started using words like "Earth" or "Erde" to refer to the planet as a whole and not just the ground they walked on. Back in 1783, German astronomer Johann Elert Bode named the seventh planet from our sun "Uranus" (after a Greek god).
Washington, DC—Our planet's water could have originated from interactions between the hydrogen-rich atmospheres and magma oceans of the planetary embryos that comprised Earth's formative years, according to new work from Carnegie Science's Anat Shahar and UCLA's Edward Young and Hilke Schlichting.
Miller and a few other scientists began to suspect that life began not in warmth but in ice—at temperatures that few living things can now survive. The very laws of chemistry may have favored ice, says Bada, now at the Scripps Institution of Oceanography in La Jolla, California.
