often differs from the climate of today. Those evidences lead him to publish Wegenerfs theory of gcontinental drafth in 1915. In the book The Origin of Continents and Oceans‚ he wrote about 300 million years ago‚ continents were a single mass‚ Pangaea‚ which had split and lifted‚ and the pieces had been moving since then. However‚ his theory was lack of explanation of how the continents move. He explained it that it was through the earthfs crust and centrifugal and tidal forces that move the

divergent movement‚ the most common of the three types of movement between plates. The other two movements are called convergent and transform-fault. This idea was first suggested by Alfred Wagener in 1915. He called the single large continent Pangaea. Today‚ there are many different kinds of evidence that support continental drift. Some of the evidence includes: • Alfred Wagener examines the location of tiny rocks and the direction of grooves. These were formed by large glaciers scraping

Later that month‚ Columbus sighted Cuba and believed it was mainland China; in December the expedition found Hispaniola‚ which he though might be Japan. There‚ he established Spain’s first colony in the Americas with 39 of his men. In March 1493‚ the explorer returned to Spain in triumph‚ bearing gold‚ spices and "Indian" captives. He crossed the Atlantic several more times before his death in 1506; by his third journey‚ he realized that he hadn’t reached Asia but instead had stumbled upon a continent

‘Evaluate how plate tectonics 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

meteorology‚ astronomy‚ and geology. He was one of the first scientists to theorize about the continental drift or continents in motion‚ which supports the belief that the Earth’s continents once were a single land mass. Wegener called this land mass‚ "Pangaea"‚ because the continents began to break up‚ and various parts drifted away from one another. According to Wegener‚ “the eastern shoreline of Africa and the western shoreline of South America fit together like a piece of jigsaw puzzle‚ and when you

I recently read a few sections in the book: Everything you wanted to know about Indians but were afraid to ask by: Anton Treuer. The sections I read from the book were based on terminology and history of Native Americans. The book states facts about terminology of identifying Native Americas. Over the years many terms were giving to Indians some being appropriate and others not so appropriate. Reading this books gives incite to people whom are unaware of the history and meaning of terms given to

The first super continent as far as I had known was Pangaea but the video takes you back even farther into earth’s history and scientist now believe the first super continent was actually Rhrodinia. Another thing is that I do believe that these super continents did actually exist because of the way the continents
