explorers/settlers clashed with the Native Americans. First and foremost‚ the geographical evolution of North America came to be from the continental shift. Some 225 million years ago all the continents were one whole together‚ known as the Pangaea. The Pangaea existed in the early Paleozoic and the Mesozoic era. It formed approximately 300 million years ago‚ and began to break apart some 100 million years later. This is known as the continental drift. The continental drift formed the great landmasses

South America. The Prologue of Crosby’s book questions the domination of these Neo-Europes. Was the European success due to their organization and technology? Perhaps simple biological factors are responsible. The idea of one land mass‚ or Pangaea‚ is depicted in Crosby’s first chapter. When the mass began to split and divide into individual continents the plants‚ animals‚ and humans were separated by large bodies of water. Development was diluted into separate regions causing a strain on ecological

Lesson 13.6 HOW WAS THE PHILIPPINE ARCHIPELAGO FORMED? In 1912‚ Alfred Wegener proposed the past existence of a supercontinent called Pangaea (or Pangea). According to Wegener‚ Pangaea had split apart into a northern half called “Laurasia” and a southern half called “Gondwanaland”. Surrounded by a global ocean called “Panthalassa” and separated by a big body of water called “Tethys Sea”. The slow drifting of continents has been occurring over the past 250 million years. In the 1960s‚ the theory

other‚ then surely there must have been a different set up to the one we have now. There is a theory that we were once a supercontinent called Pangaea that began to break up around 200 million years ago. Using plate tectonics‚ we can explain‚ predict and see which type of seismic and volcanic events are related to plate tectonics‚ using more theories like Pangaea to explain them. Covering our earth’s surface there are seven major plates. These plates cover the inside structure of our earth‚ which consists
