ancient world map

ancient world map Second, the Cambrian - pernol mainland Asia and the collapse of the big bang life In the Cambrian, animals with hard shells in large quantities for the first time, many of the continents were flooded by shallow seas, the supercontinent of Gondwana (Gondwana) are formed near the South Pole. Formed in the late Precambrian (about six hundred million years ago) of the supercontinent pernol (Pannotia), at the beginning of the Paleozoic time division, a new - old Atlantic Ocean (Iapetus Ocean) in lauren (Laurentia, North America), Baltic (Baltica, northern Europe) and Siberia (Siberia) expansion between the several ancient continent. (Gondwana supercontinent of Gondwana) in the pan-african fold belt at the time the largest continent, ranging from the equator to the South Pole. Third, ordovician - from warm to cold In ordovician period, the warm water limestone and gypsum precipitation in the equatorial regions of gondwana continent (Australia, Australia, India, India, China, China and Antarctica Antarctica), and in the rest of gondwana continent of Antarctica, Africa and South Africa America South America) are precipitated the glacier ice sedimentation and floating debris. In ordovician period, the ancient sea lauren Asia (Laurentia), polo, Baltica, Siberia and Gondwana (Gondwana) (Siberia) these ancient continental divide. By the end of ordovician, climate into one of the coldest period on earth, snow covered the whole of the southern half of gondwana continent. In ordovician, many tensile fracture basin makes the ancient continent lauren josiah, polo, Siberia and the separation of gondwana continent, including ancient Atlantic (Iapetus Ocean) separated from the Baltic and the Siberian continent, closed since the Atlantic Ocean, formed the caledonian mountain (Caledonide Mts.) the Appalachian mountains and north (Appalachian Mts.). And the ancient Mediterranean (Paleo - Teyhys Ocean) the gondwana continent from the Baltic and the Siberian continental divide the, the giant ancient oceans (Panthalassic Ocean) are covered when most of the northern hemisphere. In the ordovician "icehouse" end of the world, has entered a great ice age. Can achieve 3 km, the thickness of the ice sheet covering the most (Africa) of northern and central Africa and parts of South America (Amazonia, the amazon basin). Ice cap from the ice-cold meltwater, freeze the world's oceans, lead to life in a large number of creatures near the equator warm water species extinction. Four, silurian, caledonian fold belt, the origin of the fish and the first land plants Lauren (josiah Laurentia) collisions with polo continent (Baltica), makes the Atlantic (Iapetus Ocean) of the north branch is closed, and formed the "Old Red Sandstone (Old Red Sandstone) continent. Coral reefs around expansion, terrestrial plants began to mainland barren" migration ". In the middle of the palaeozoic (some four hundred million years ago), ancient Atlantic closed that lauren with Baltic continental collision. Appeared in many parts of the continental collision, the overlying continental margin arc movement, led to the Scandinavian peninsula (Scandinavia) on the caledonian mountain (Caledonide Mts.) is formed, and the (Great Britain), in northern Greenland (Greenland), and to the North of the east coast of North America (North America) the Appalachian mountains (Appalachian Mts.) are formed at the same time. Also in the middle of the Paleozoic, very similar cases in North China landmass (North China) and South China continental block (South China) since the Gondwana continent (Gondwana) "India - Australia" (India - Australia) edge drifted apart, moving North and across the ancient Mediterranean (Paleo tethys Ocean). From the early Paleozoic to middle, wide range of ancient oceans (Panthalassic Ocean) is covered most of the northern hemisphere, at the same time around the sea around the plate subduction zone, much like today's around the Pacific "ring of fire" (ring - of - the fire).Five, the prelude to devonian, hercynian movement, and the origin of the amphibians, the forest began to emerge Closed early Paleozoic Marine in devonian period, forming "pangu" (Pangea) of mainland China. Freshwater fish started from the southern hemisphere land to migrate to North America (North America) and Europe (Europe). Forest is the first time appear in the equatorial regions of ancient Canada (Canada, near the arctic today). Devonian period belongs to the world of the "fish", chin evolved in the early devonian have fish in the late devonian to become the top predators. Plants at this time also began to appear a lot of on land, at the same time the earliest "coal", formed in the tropical swamp area is covered most of the islands, the north near Canada polar Greenland today (Greenland) and Scandinavian (Scandinavia), etc. The origin of the six - reptiles, early carboniferous epoch and the formation of coal, the ice again In the early carboniferous, continental Europe and the United States (Euramerica) and Gondwana continent (Gondwana) between the Paleozoic Marine began to close, formed the Appalachian mountains (Appalachian Mts.) and vailixi as mountains (Variscan Mts.). (Antarctica) began to form at the South Pole ice cap at the same time, the four-legged reptiles successional, equatorial regions begin to form coal swamp. Seven, - the late carboniferous to the equatorial rain forest and the Antarctic ice sheet, the prototype of pangea During the late carboniferous, of North America and northern Europe continent and the southern Gondwana continental collision (Gondwana), formed the Pangea (Pangea) western half. Snow and ice covered the Thai at this time and a half of the southern hemisphere, while huge marais coalfield formed near the equator. . By the end of the Paleozoic, most of the time in pernol (Pannotia) supercontinent he during open ocean, are due to the collision between the mainland and the mainland later, and form a new supercontinent pangu (Pangea) after running out. Centered around the equator, pangea extend from the South Pole to the North Pole, and the ancient Mediterranean (Paleo Tethys Ocean) and ancient (panthalassic) space in the east and west on both sides of the Pacific Ocean. During the late carboniferous to early Permian, the South of pangea (including South America South of South America, Africa, southern Africa, Antarctica, India India, southern India and Australia, Antarctica) Australia is covered with ice. Evidence also shows that in the late Permian, the arctic ice cap in eastern Siberia (Siberia). At the same time in the late carboniferous period, is located in the middle of pangea broad mountains has formed the equatorial highland, local and become the scene of the equatorial rain forest form the coal. In the middle of the Permian, pangu central mountains north moved to North America and northern Europe the internal dry climate zone, become similar to the weather of the desert. From the mountains rise blocks the equator wind belt waft of water vapor. The word "pangu" means "all the mainland", although we called "pangu" of the supercontinent formed in late Paleozoic, but the supercontinent in the then still seems not contain all of the land, on the right side of the eastern hemisphere - the ancient Mediterranean, there is still a separation in the mainland's land. These is South China, North China landmass (South and North China), and a long "windshield" shaped sheen has mainland (Cimmeria). Simba has included mainland have Turkey (Turkey), yi (irfan), Afghanistan (Afghanistan), Tibet (.tibet), Indochina (Indochina) and Malaya (Malaya). The continent seems to be a late stone carbon to early Permian period, from Gondwana continent (Gondwana) "India - Australia" (India - Australia) on the edge of separation. Combined the Chinese continental blocks, idea of continents move toward north Eurasia, finally in late Triassic, hit the south edge of the Siberia (Siberia). Hence these broken in Asia continental after crash into each other, all the land in the world and all joined the supercontinent,Form the veritable pangea. Eight, the Permian - desert covered mainland and the coming of the extinction the Permian period, huge desert covers Pangea (Pangea) western half, at the same In time, the entire surface of the supercontinent reptiles distribution. But at the end of the Paleozoic era, 99% of the life on the earth are subjected to extinction event of disaster. Nine, Triassic, pangea molding and the origin of the occurrence of dinosaurs, mammals About in the Triassic period of Pangea (Pangea), makes the land animals to migrating from the South Pole to the arctic. In life after Permian - Triassic mass extinction, restart diversity, rich rise. At the same time warm water species distribution across the whole of the ancient Mediterranean. Made up by pieces of pangea, it began in the formation of devonian period, through the continuous collision between mainland and the mainland each other, until the late Triassic, led to the forming of the supercontinent. Ten, early Jurassic - a prelude to the disintegration of the indosinian movement, the origin of birds Pangea did not immediately he, it is similar to the three phase split into smaller landmass. The first stage in the middle of the Jurassic (about one hundred and eighty million years ago), tensile fracture activity to begin. Through a phase, along the North America (North America), Africa (Africa) northwest and east Atlantic (Atlantic Ocean) in the center of the igneous activity, will be to the northwest of North America. Far away from each other at the same time in South America and North America, the Gulf of Mexico (Gulf of Mexico) began to form. At the same time, in the other side of the Africa, due to the extension in East Africa, the South Pole (Antarctica) and Madagascar (Matagascar) boundary of the volcanic eruption, forecast the western Indian Ocean (West Indian Ocean). In the period of the Mesozoic, North America and Eurasia is the same continent, we sometimes call lauren (Laurentia). When the central Atlantic start splitting, lauren Asia continent Yu Shishun clockwise, push North America to the north, Eurasia moved southward. Early Jurassic coal in east Asia a lot no longer see, because of the Asian continent and wet climate zone to the subtropical dry area, so instead of late Jurassic desert and salt deposits. Lauren Asia continent the clockwise movement, led to the original split it from gondwana continent of v-shaped ancient Mediterranean (Paleo Tethys Ocean) began to close. In the early Jurassic, the Southeast Asia (Southeast Asia) polymerization. A broad ancient Mediterranean Sea to the north of mainland and Gondwana continent (Gondwana) separated in two places. While Pangea (Pangea) is still a shutout motionless, but the earliest stories about the split has been can vaguely heard it. 11, middle and late Jurassic, the birth of the Atlantic Pangea (Pangea) division, the start of the middle Jurassic to late Jurassic the Central Atlantic (Central Atlantic Ocean) have tumbled into a narrow sea, separating the eastern North America and North America. East butte wana (Gondwana) at the same time also with western Gondwana began to split. 12, the early cretaceous, the break-up of gondwana and the expansion of the shallow water, the Rocky Mountains to form During the cretaceous period, the South Atlantic (the South Atlantic Ocean) open. India (India) from Madagascar (Matagascar) separation, and accelerate to the north, to the location of the Eurasia, Eurasia collision. It is worth noting that the North America (North America) and Europe at the moment still connected, and Australia (Australia) at this time also belong to a part of Antarctica (Antarctica). Pangea (Pangea) division of the second phase began in the early cretaceous, about one hundred and forty million years ago. Gondwana continent (Gondwana) constantly become broken, including the south Atlantic tumbled, separated from South America and Africa; And India and Madagascar from Antarctica drifted apart together;Also occurred in west Australia east Indian Ocean tensile fracture, and so on. South Atlantic did not immediately open at this time, but like unzipped gradually from south to north is open. This is also why the south Atlantic relatively wide. In addition, there are some important tectonic events took place in the cretaceous period. This includes: North America and Europe began to drift apart, the Iberian peninsula (Iberia) counterclockwise to leave France (France), separating India from Madagascar, Cuba and heath of the Cuba Mr Mourinho pull (struck, the west Indies) from the Pacific Ocean (Pacific Ocean) derived, Rocky mountains (Rocky mountains) rise, exotic piece of blue, lu (Wrangellia, near Alaska), Steve golden Virginia near (Stikinia, Canada) to arrive at the north west margin. Cretaceous period of the global climate is similar to Jurassic and Triassic period, much warmer than it is today. Dinosaurs and palm trees can appear in the Arctic Circle (Artic) today, the South Pole (Antarctica) and Australia (Australia) in the south. Although there may be some early cretaceous period of the polar ice caps, but the Mesozoic has any massive ice cap. Cretaceous period so mild weather conditions, partly because of shallow water covers most of the land. Warm water can be transported by north from the equator region, bring warmth to the polar region. The shallow water at the same time, it makes some parts of the climate mild, just like today's Mediterranean can improve the climate of Europe as useful. Because the sea surface height 100 ~ 200 meters higher than today, make the shallow sea to cover many land. High on the surface of the water start splitting, in part because of the new basin ridge replaced water in the oceans, makes the water spilled upon the land. Cretaceous is also fast spurted period of basin, due to their broad shape and the ridge in the rapidly expanding and replace more water, so in the period of rapid expansion in seabed, will tend to rise of sea level. 13, the late cretaceous - India continental blocks northward and shallow sea continues to expand, the dinosaurs Pointed out just the eyes marks the location of the khosla "Chicxulub impact site, the diameter of 10 mile (16 km) as a result, the size of comets lead to global climate change, killed the dinosaurs and many other forms of life. Sea in late cretaceous become more broad, and India (India) is becoming more and more close to the southern Asia (Asia). 14, -- the formation of the qinghai-tibet plateau in paleogene and the disappearance of the ancient Mediterranean About fifty million to fifty-five million years ago, India (India) began to hit the n continent (Asia), (sect) formed on the Tibetan plateau and the Himalayas Asia (Himalayas). Originally linked to the Antarctic continent (Antarctica) Australia (Australia), the land at this time also started to drift quickly to the north. Pangea (Pangea) the division of the third stage, and final stage, began in the early Cenozoic. North America (North America) and Greenland (Greenland) (Europe) drifted apart from Europe, the continent release Australian landmass, release of the India plate as fifty million years ago, then quickly moving North and into southeast Asia's position. Today most of the splitting activities, both occurred twenty million years ago, include: Red Sea (Red Sea) of tensile fracture make the Arabian peninsula (matter) (Africa) drifted apart from Africa, east Africa, tensile fracture system, and the Sea (Japan Sea) of tensile fracture, Japan's move to the east into the Pacific (Pacific Ocean), and the Gulf of California (Gulf of California) in the open, in northern Mexico (Mexico) and California (California) northward movement together. Although many new basin during Cenozoic open, but the past sixty-six million years of earth history is the mainland in the era of the fierce collision.Only a few times in the history of the earth's ever so cold as in the past five hundred years.
