How significant was Mazzini in the growth of opposition to autocratic and foreign rule in Italy in the years 1831–49? (30) Mazzini was a republican nationalist who had a significant effect in the growth of anti-autocratic feeling in Italy. He had radical aims for the future of Italy and he envisioned unification. He was the first leader to indoctrinate in the minds of Italians a vision of political unification. Mazzini created the Young Italy society after the 1831 revolutions.
He claimed that each of the present continents was once joined together as part of a super continent called Pangea. He believed this because he saw that in certain areas continents would fit together for example the west coast of Africa fits together with the east coast of South America, therefore they must have moved apart from one central mass. Other evidence was shown to back up this theory such as the fact that glacier derived clays are found in all of the continents in Gondwana forming one half of Pangea, as one striations in rocks of Carboniferous age. Presently they cover half the globe but would form a reasonably sized polar ice cap if Wegener’s theory was true and the globe was reconstructed in his image of how it used to be. Despite Wegener having no concrete proof as to why this was the case his theory was proved to be accurate, physicists had believed that the earths crust was far from strong enough to be able to force itself apart.
The women in Dadi’s family mostly dominate the agricultural process and distributions, and also care for the household. The men, however, represent the family politically and dominate agricultural production. The role for men in Dadi’s family is basically to be the governing leader while the women work hard both in the field and at home. Many husbands expect their wives to perform labor in the field, fetch water and cow dung, and still have food and water waiting at home for them. Many women in India, especially in Dadi’s family, suffered from many
First proposed by Alfred Wegener the meteorologist, the theory of continental drift supports the belief that the Earth's continents once were a single land mass. This land mass, which was named "Pangaea", broke up, and it's various parts drifted away from one another. Centuries ago, trips around the world from travelers showed out lines from every continent around the world. Later on, early mapmakers wondered why these continents fit together so well. Early geologist thought at first that the continents had started off in their places they laid in the present day.
Wegener's theory also provided an alternate explanation for the formation of mountains (orogenesis). The theory being discussed during his time was the "Contraction theory" which suggested that the planet was once a molten ball and in the process of cooling the surface cracked and folded up on itself. The big problem with this idea was that all mountain ranges should be approximately the same age, and this was known not to be true. Wegener's explanation was that as the continents moved, the leading edge of the continent would encounter resistance and thus compress and fold upwards forming mountains near the leading edges of the drifting continents. The Sierra Nevada Mountains on the Pacific coast of North America and the Andes on the coast of South America were cited.
is quite late in the history of the Universe, which -- as we told you in our lastInstruction -- is thought to have begun about 15 million years ago with an almostunimaginable explosion called The Big Bang.At first, the Earth was just a ball of molten rock and gasses. As it began to cool,dense materials like iron sank down into its core. Lighter materials likecompounds of oxygen and water rose toward the surface.That's why the Earth is made up of different layers -- as you can see in this crosssection:There are three layers in the Earth: the Crust, the Mantle and the Core.

What lead to their extinction will be discussed in this case study. As can be seen from the geological time scale above the dinosaurs existed for around 230 million years then 65 MYA they just simply disappeared, Dinosaurs first appeared during the Triassic period, around 230 MYA these very quickly become the dominant terrestrial vertebrates for 135 million years, from the beginning of the Jurassic right through to their extinction in the Cretaceous period. However, there is evidence in the fossil record that shows some birds survived the extinction event that occurred 65 MYA, and they continue the dinosaur’s lineage today. Scientific Background The Triassic Period The Triassic Period is the first period of the Mesozoic Era, the Triassic period is also referred to as a time to grow new species to repopulate the planet. This time was the new era known as the Mesozoic Era, Geologists call it a new era because the life supported on the continents was so different from that of life during the Palaeozoic era.
Keeping watch over the Inca was a powerful leader Pachacuti who controlled his civilization with a use of various techniques. The Inca civilization of pre-Colombian American used concise and astute methods to control its peoples. The Inca civilization, also known as the Twantinsuyu commanded its people through an overpowering government which was centralized, organized and had the ability to seize a large portion of land through the use of a strong military. Inca known as Pachacuti 1438-1471 C.E. initiated military alliances and campaigns, which gave them the ability to seize lands which included the entire area from Cuzco to the shores of Lake Titicaca.
Theory of continental drift The hypothesis that the continents had once formed a single land mass before breaking apart and drifting to there present locations was first presented by Alfred Wenger. He believed that the continents were once joined in a super continent that scientists now call Pangaea. Over a vast period of time the continents drifted apart due to the earth’s rotation. In 1915 he published a book about his theory. His main evidence was the continents appear to have a jigsaw like fit, the west coast of Africa and South America have the same pattern of rock layers and have the same plant and animal fossils; some of these animals are only found in those parts of the world and their fossils show they could not swim.
Wenger’s proposition was that the continents were slowly moving along with tectonic plates and that was why they shifted position on the earths surface, the evidence to support his theory was the same plant fossils and similar rock formations all found on different continents. Wenger believed that the continents had once formed to make one whole continent known as Pangea, which is Greek for ‘all the lands’. According to Wenger’s theory Pangea began to break up about 225-200 million years ago and eventually fragmented into the continents we know
