  Russian Federation – Physical

  $3.95

  Prior to its dissolution in 1991, the USSR was 24.4 million square miles (63 million square Km) and covered a sixth of the world’s land surface. It straddles two continents, Europe and Asia, with the Ural Mountains, running through Chelyabinsk and Perm, acting as a partition. Russia has vast natural... More

  The Geography of the Muslim Lands c. 2000

  $3.95

  The Muslim world (2000) is a vast region that stretches from northern and sub Saharan Africa, through the Middle East, Balkans, Central Asia, southern Philippines and into Malaysia and Indonesia in Southeast Asia. Major populations tend to be concentrated in arid zones, such as northern and sub-Saharan Africa or Kazakhstan,... More

  The Jurassic World 220–145 million years ago

  $3.95

  The Jurassic period saw the continuation of the breakup of the primordial supercontinent, Pangea. A large southern continent, Gondwanaland, was balanced by a northern continental cluster, Laurasia. Here intense submarine volcanic activity caused the spreading of the ocean floor, in turn triggering subductions that would ultimately extrude the Andean, Tibetan... More

  The Lower Carboniferous World 350–315 million years ago

  $3.95

  In the Lower Carboniferous, high sea levels meant that the northern hemisphere was almost devoid of land. The island of Angaraland was the only significant landmass north of the equatorial zone. Laurentia, comprising what would become North America and northern Europe, was still separated by straits from the main landmass... More

  The Lower Devonian World 410–380 million years ago

  $3.95

  In the Lower Devonian, a secondary supercontinent to Gondwanaland was formed by the collision of Laurentia and Baltica; amongst its repercussions were the raising of the Appalachian and Caledonian Mountains. The two early supercontinents were encircled by subduction zones that would lead, eventually, to the creation of the supercontinent of... More

  The Ordovician World 500–440 million years ago

  $3.95

  During the Ordovician, there were no landmasses in the northern hemisphere, which was entirely covered by the global ocean of Panthalassa. The southern continents were fused into the supercontinent Gondwanaland, which started the period abutting the equator, but drifted steadily southward. To the west of Gondwana, between the equator and... More

  The Silurian Word 440–410 million years ago

  $3.95

  During the Silurian period the giant southern supercontinent arced upwards through a broad peninsula, formed by Antarctica and Australia, which straddled the equator. While there was no major volcanic activity at this time, the smaller landmasses of Laurentia, Baltica and Avalonia, composing what would become North America, steadily converged together.... More

  The Triassic World 250–200 million years ago

  $3.95

  Almost all the earth’s landmass was conjoined in a vast C-shaped continent astride the Equator: Pangea. Surrounding it was Panthalassa, a vast ocean twice the breadth of the modern Pacific from which protruded the Tethys Ocean, a huge gulf forming the mouth of Pangea’s ‘C’. Much of present South and...

  The Upper Carboniferous World 315–290 million years ago

  $3.95

  In the Upper Carboniferous, the fusion of Laurentia with Gondwanaland forced up ranges of mountains through the Appalachian–Hercynian orogeny (a mountain-building process). Of the resulting landmass, only the land that is now North America sat astride the equator, with Angaraland, containing present day Siberia/Kazakhstan a large island to the north.... More

  The Upper Devonian World 380–350 million years ago

  $3.95

  The Upper Devonian had significantly higher sea levels than today, with most of the Earth’s surface covered by the vast Panthalassa Ocean. Proto Europe and North America existed as islands skirting the continent of Laurentia, which had collided with Baltica in the Lower Devonian. The main landmass, Gondwanaland, lay to... More

  The Virgin Lands 1960–70

  $3.95

  In 1953, the new Soviet leader, Nikita Khrushchev, began the Virgin Lands campaign to cultivate the steppe lands, mainly in northern Kazakhstan, for grain production. This area was chosen because it had higher rainfall and better soil than neighbouring regions, as well as a low population. The campaign was successful... More

  Transformation of American Flora 1620, 1850, 1990

  $3.95

  When Europeans first arrived, America’s indigenous population were either nomadic or subsistence hunters, managing, rather than supplanting, the native vegetation. During the 18th century, the colonization of the eastern seaboard saw natural forest cover replaced with plantation monocultures to the south, mixed arable farming to the north. During the 19th...
