Theory of Continental Drift The seven continents used to be one giant continent named Pangea. They spread apart and became what the continents are today. The shapes of the continents line up‚ the fossils line up with how the continents‚ the rock formations on both sides of the Atlantic line up with the fossils and coastlines‚ and climatic evidence proves the Theory of Continental Drift. The first piece of evidence for Continental Drift is the shapes of the continents. All of the continents fit

Family Doctor Ever since I started to watch ER at the age of fourteen‚ I have formed a fascination for the medical field. The best component of the job is saving one’s life.

both formed and broken apart millennia ago‚ Pangaea connected the world together in a way that was and will mostly likely never been seen again. With one giant super continent connecting people of completely different backgrounds and ethnicities‚ Pangea allowed for the flow of ideas and resources across on open sourced area. However‚ after the breaking of Pangaea‚ the continents would not come in contact again for hundreds of years and even longer when separated into different hemispheres. However

James Hutton discovered that the earth was much older from the tilted rocks because he knew these rocks was once laid down horizontally on the sea floor and were buried under great depth to be crystalized. Then they were tilted on end by great

the origins of the horseshoe-shaped lowland that is underlain by massive quantities of sand‚ silt and mud deposits. They begin at what geologist call Pangea‚ which is when North America‚ South America‚ Africa and Eurasia came together to form one supercontinent. This collision raised several mountain ranges‚ including the Ouachita-Appalachian. Pangea is said to be ripped apart where it had previously been sutured together: just outside the arc of the Ouachita-Appalachian Mountains. This opening

INTRODUCTION Plate tectonics The large scale motions of the earth’s lithosphere are describe by a scientific theory called plate tectonics which explains that Earth’s outer layer is made up of plates‚ which have moved throughout Earth’s history. The theory was developed during first decade of 20th century (by a famous advocate Alfred Wegener) on the older concept of continental drift and was accepted by many geoscientific communities. There are currently seven major and many minor plates are

The continental drift theory was first proposed by a German called Alfred Wenger in 1915. He suggested that the earth’s continents were once joined together‚ but gradually moved apart over millions of years. This once ‘supercontinent’ was known as Pangea – which translates to ‘’All Earth’’. Pangaea started to break up into two smaller supercontinents‚ called Laurasia and Gondwanaland‚ during the Jurassic period. By the end of the Cretaceous period‚ the continents were separating into land masses that

The Appalachian Mountains The Appalachian mountain system dominates the Eastern United States and seperates the Eastern seaboard from the interior with a belt of uplands that extends nearly 1‚500 miles from northeastern Alabama to the Canadian border.; They are old‚ complex mountains‚ eroded from much older and greater ranges. The present topography is a result of erosion that has carved the weak rocks away‚ leaving a skeleton of resistant rocks behind as highlands. Because of this weathering‚ geologic
