called “Panthalassa”. The pieces of the supercontinent were giant plates that fit together like a jigsaw puzzle. Through years and years of continental drift‚ the giant jigsaw pieces became the continents of the world we know today. The splitting apart of the continents gave way to new oceans. The continents continue to drift today. Our oceans are constantly moving. The Atlantic and Indian Oceans move apart one to six inches a year. While the Atlantic and Indian Oceans are growing wider‚ the Pacific

ridges is called seafloor spreading. The most common processes occurring along divergent boundaries are volcanism and earthquakes. Many divergent boundaries are formed when a continent rifts apart and a midocean ridge forms between the two halves of the continent. Fault bounded rift valleys form at the edges of the continents that fill rapidly with relatively immature sediment and form rocks like arkosic sandstone and shale. These deposits‚ called red beds‚ are characteristic of the continental margins

Once the Insular Plate stopped subducting under North America‚ the collision stopped. Unfortunately for the Bridge River Ocean‚ it got caught between the Insular Islands and the continent and ended up closing when the violent collision took place. What did the Insular Islands become? What were the Insular Islands is now known as the Insular Belt‚ which is a major geologic feature along the west coast of Canada that stretches into

Why is the role of trade important for one to understand when studying Africa? Be sure to include examples from all over the African continent in addressing your answer. Olivia Griesmer The role of trade is very important to understand when studying Africa because it was the major way people gained wealth. Much of Africa is desert and dry and hard to farm on so trading was how much of Africa made its wealth. In the area known as Nubia a large trade and emerged with Egypt. They traded ivory

theory helps our understanding of the distribution of seismic and volcanic events’ In 1912‚ Alfred Wegener published his theory that a single super continent named Pangaea once existed about 300 million years ago. He proposed that Pangaea then later split into two continents of Laurasia in the north and Gondwanaland in the south and that today’s continents were the result of further splitting of these two land masses. Where the plates split are known as plate boundaries. Wegener’s theory of continental

Introduction: Colonialism has been recognized historically as a tool of domination‚ typically following the military subjugation of one people by another. It is a process whereby the colonizer‚ mother country‚ invades and then exercises sovereignty over the colony and its indigenous population primarily for economic exploitation. It creates a master-slave relationship between the mother country and the new colony‚ whereby the vast resources and indigenous population of the colony exist to serve

The solid Earth system consists of the nonliving solid Earth from its center to its surface‚ including continents and seafloor. The atmosphere comprises the gaseous envelope surrounding Earth.

‘The Atlantic Slave Trade’ was authored by the Historian Herbert Klein in 1999 to account for the history of the Trans-Atlantic trade that saw thousands and thousands of African slaves across the sea to become property. The historian attempts to eliminate the myths that surround these events and the consequent misperceptions derived from them and accepted as facts across cultures. The facts that he presents are backed up by statistics and as such have a lot of weight. While his book is enlightening

Prior to European colonialism‚ South America belonged to the indigenous populations.

When European explorers began to leave the old continent in search of new trade routes to China‚ Africa‚ along with Asia‚ with their ultimate goal of gaining a foothold in the quest for the various valuable commodities and items it possessed (Strayer 581). Europe did not appear to be destined to be in the lead for the inevitability of global dominance. Henceforth‚ there were a few factors‚ which would eventually contribute into them doing so‚ with the key primary aspects being the establishment of
