The War Of 1812 And The United States Essay - 1328 Words
The War of 1812 was the result of an ongoing feud between France, Great Britain, and the United States. The causes of the war included Britain attempt to restrict trade between France and the United States, Britainââ¬â¢s navy intimidating American seamen and the U.S. attempt to expand their territory. Before going into the war, the United States was fully aware that Britain had the greatest naval power in the world so this would be the costliest war financially and physically. The United States knew that this conflict with Great Britain would have a tremendous impact on the countryââ¬â¢s future so they had to address the issue immediately and aggressively. But the United States defeated Britain once before they knew they can defeat them once again. Many people considered the War of 1812 the United States second war of independence because once again they were facing Great Britain. The conflict between France and Great Britain (French Revolutionary and Napoleonic Wars) set the t one of the War of 1812 Both nations were trying to prevent the United States from trading with the other. The Jayââ¬â¢s Treaty of 1794, settled many unresolved issues between the United States and Great Britain. One of these issues was that of trading goods with France. Of course, Britain considered France the enemy, therefore they wanted the United States to have nothing to do with their enemy. The Jayââ¬â¢s Treaty allowed for Britain to seize any U.S. goods headed for France, but only if they paid for them.Show MoreRelatedThe United States And The War Of 18121144 Words à |à 5 Pages The United States of America triumphed in the Revolutionary War, emerging as an independent nation.

Leonidas did not want to disobey the priests, so he decided to take 300 of his best soldiers, as his bodyguards, and take a walk to the Hot Gates of Thermopylae. Along the way, King Leonidas and his 300 soldiers met some allies. The allies were shocked by the small number of Spartan soldiers, but when Leonidas asked their professions, he clearly stated he had brought more soldiers than them. The Spartans continue their journey and are joined by Arcadians and other Greek forces. When they arrive, the build a wall to slow the Persian attack. The soldiers fight off the Persian scouts, and use the dead bodies to increase the massive wall. The scouts are followed up by a Persian emissary, who threaten to ââ¬Å"block out the sunâ⬠with their arrows and King Leonidas replies that the Spartans will fight in the shade. The Spartans battle and defeat the Persian emissary. The Persians demand that the Spartans surrender before anyone else dies, but King Leonidas refuses and the two forces have a huge battle with many causalities.

The Tale of the Peculiar Girl free essay sample
Once upon a time, in a kingdom far, far away, there lived a peculiar girl. She had cropped hair flecked with damp Pacific sand and deep knowing eyes the color of a red cedar in the rain. Every day the girl awoke in her bedroom built of music and books, looked into the ominous dark forest, and decided whether it would be a Birkenstocks with socks day or a Birkenstocks without socks day. She ate her porridge of oats, soy milk, and fruit, drank her bitter coffee in just two gulps, and walked outside into the temperate rainstorm. Such was each morning, and each morning was good. The young girl asked many questions, and in this way she learned about the world. Soon her brain began to see the days as parabolas, the conversations as chords and dissonances, and the friendships as woven baskets. The Earth became magical and hope became truth. We will write a custom essay sample on The Tale of the Peculiar Girl or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page One day, a great storm befell the kingdom. The storm was like nothing the young girl had ever seen, and was not from the skies. Inside her heart and her soul and her mind the storm raged ââ¬â for the peculiar girl had realized that in all her questioning, not once had she asked what was right and what was wrong. Heeding the darkness of the storm, she embarked on a quest for enlightenment. A great many years later, the not-so-young girl arrived at a castle where she was to learn the algorithms and words and ideas of the world. This castle was ruled and its laws set by the King of Catholicism from his distant home in Vatican City. The girl did not understand these strange laws. She did not understand why a King who preached love would spread inequality. She did not understand why two citizens who wholly loved each other must be banished if they happened to be both women or both men. And she did not understand why the King refused to allow his citizens to question these laws. The peculiar girls mind churned for days and weeks and months until she knew she must disobey the laws of the great King. On the sunniest day of the fourth month of the second year, the girl approached the leader of the castle. Seeking permission to form a group for women who love women, men who love men, and the vast number of people falling in between, the girl begged the leader using every magical potion of persuasion she possessed. But the leader would not yield, and the girl was denied. That night, she cried and cried until her tears watered an idea; the peculiar girl would have to form the group in secrecy, for its existence was still vital to the Kingdom. She found several citizens and a location in the basement dungeon of the nearby castle, and in this way, her idea grew. The first of many meetings of this group was filled with tearful stories, hopeful smiles, and devious plans. With each week, the group gained confidence, allowing ideas to escape from the dungeon with petitions, letters, interviews, rumors, and hope. In the years that followed, the not-so-young-but-still-peculiar girl continued to water her idea and her idea continued to grow. Baskets were woven, chords created, and parabolas summited. Soon, the idea grew so large that the greatest of storms could not overpower it ââ¬â and the storm of the girls youth had passed. The girl was good and her future was bright. No longer confined to her fairy tale, the peculiar girl has begun to seek a new castle with a benevolent ruler in which she might pursue the true wisdom of the world and live happily ever after.

Rock Provenance by Petrologic Methods
Rock Provenance by Petrologic Methods Sooner or later, almost every rock on Earth is broken down into sediment, and the sediment is then carried away somewhere else by gravity, water, wind or ice. We see this happening every day in the land around us, and the rock cycle labels that set of events and processes erosion. We should be able to look at a particular sediment and tell something about the rocks it came from. If you think of a rock as a document, sediment is that document shredded. Even if a document is shredded down to individual letters, for instance, we could study the letters and tell pretty easily what language it was written in. If there were some whole words preserved, we could make a good guess about the documents subject, its vocabulary, even its age. And if a sentence or two escaped shredding, we might even match it to the book or paper it came from. Provenance: Reasoning Upstream This kind of research on sediments is called provenance studies. In geology, provenance (rhymes with providence) means where the sediments came from and how they got where they are today. It means working backward, or upstream, from the grains of sediment we have (the shreds) to get an idea of the rock or rocks they used to be (the documents). Its a very geological way of thinking, and provenance studies have exploded in the last few decades. Provenance is a topic confined to sedimentary rocks: sandstone and conglomerate. There are ways of characterizing the protoliths of metamorphic rocks and the sources of igneous rocks like granite or basalt, but theyre vague in comparison. The first thing to know, as you reason your way upstream, is that transporting sediment changes it. The process of transport breaks rocks into ever smaller particles from boulder to clay size, by physical abrasion. And at the same time most of the minerals in the sediment are chemically changed, leaving just a few resistant ones. Also, long transport in streams can sort out the minerals in sediment by their density, so that light minerals like quartz and feldspar can move ahead of heavy ones like magnetite and zircon. Second, once sediment arrives at a resting place- a sedimentary basin- and turns into sedimentary rock again, new minerals may form in it by diagenetic processes. Doing provenance studies, then, requires you to ignore some things and visualize other things that used to be present. Its not straightforward, but were getting better with experience and new tools. This article focuses on petrological techniques, based on simple observations of minerals under the microscope. This is the kind of thing geology students learn in their first lab courses. The other main avenue of provenance studies uses chemical techniques, and many studies combine both. Conglomerate Clast Provenance The big stones (phenoclasts) in conglomerates are like fossils, but instead of being specimens of ancient living things they are specimens of ancient landscapes. Just as the boulders in a riverbed represent the hills upstream and uphill, conglomerate clasts generally testify about the nearby countryside, no more than a few tens of kilometers away. Its no surprise that river gravels contain bits of the hills around them. But it can be interesting to find out that the rocks in a conglomerate are the only things left from hills that vanished millions of years ago. And this kind of fact can be especially meaningful in places where the landscape has been rearranged by faulting. When two widely separated outcrops of conglomerate have the same mix of clasts, thats strong evidence that they once were very close together. Simple Petrographic Provenance A popular approach for analyzing well-preserved sandstones, pioneered around 1980, is to sort the different kinds of grains into three classes and plot them by their percentages on a triangular graph, a ternary diagram. One point of the triangle is for 100% quartz, the second is for 100% feldspar and the third is for 100% lithics: rock fragments that havent fully broken down into isolated minerals. (Anything that isnt one of these three, typically a small fraction, is ignored.) It turns out that rocks from certain tectonic settings make sediments- and sandstones- that plot in fairly consistent places on that QFL ternary diagram. For instance, rocks from the interior of continents are rich in quartz and have almost no lithics. Rocks from volcanic arcs have little quartz. And rocks derived from the recycled rocks of mountain ranges have little feldspar. When necessary, grains of quartz that are actually lithics- bits of quartzite or chert rather than bits of single quartz crystals- can be moved over to the lithics category. That classification uses a QmFLt diagram (monocrystalline quartzââ¬âfeldsparââ¬âtotal lithics). These work pretty well in telling what kind of plate-tectonic country yielded the sand in a given sandstone. Heavy Mineral Provenance Besides their three main ingredients (quartz, feldspar, and lithics) sandstones have a few minor ingredients, or accessory minerals, derived from their source rocks. Except for the mica mineral muscovite, they are relatively dense, so theyre usually called heavy minerals. Their density makes them easy to separate from the rest of a sandstone. These can be informative. For instance, a large area of igneous rocks is apt to yield grains of hard primary minerals like augite, ilmenite or chromite. Metamorphic terranes add things like garnet, rutile and staurolite. Other heavy minerals like magnetite, titanite and tourmaline could come from either. Zircon is exceptional among the heavy minerals. It is so tough and inert that it can endure for billions of years, being recycled over and over like the coins in your pocket. The great persistence of these detrital zircons has led to a very active field of provenance research that starts with separating hundreds of microscopic zircon grains, then determining the age of each one using isotopic methods. The individual ages arent as important as the blend of ages. Every large body of rock has its own blend of zircon ages, and the blend can be recognized in the sediments that erode from it. Detrital-zircon provenance studies are powerful, and so popular nowadays that theyre often abbreviated as DZ. But they rely on expensive labs and equipment and preparation, so theyre mainly used for high-payoff research. The older ways of sifting, sorting and counting mineral grains are still useful.

Marco Polo's Travel Account Essay Example | Topics and Well Written Essays - 1750 words
Marco Polo's Travel Account - Essay Example After having analyzed Marco Polo`s travelogue in detail along with the second hand accounts on his writings written afterwards, a few patterns can be identified conveniently. These accounts suggest that the Mongolian Empire which belonged to the Kublai Khan (1214-1294) was a highly glorified one, in the sense that the architecture of the farfetched land, especially Kublai`s palace was beyond imagination, also the Mongolian culture unlike that perceived by the Westerners is a highly enriched one which escalates the senses of anyone experiencing it. Moreover, though Marco Polo had also mentioned the hardships and distance which he had to face in detail, which implies that the journey was a highly difficult one, even after they possessed the VIP pass, however on experiencing their cultures and having the experience of staying close to Kublai Khan for so long, he finally concludes that the hardships were worth it. However, those who have reflected on the works of Marco Polo have further doubted the credibility of Marco Polo on the account that neither had he learnt the Chinese language during all those years, and adding insult to injury, some of the accounts which he had presented are way too amazing to be true. "When a man is riding through this desert by night and for some reason -falling asleep or anything else -he gets separated from his companions and wants to rejoin them, he hears spirit voices talking to him as if they were his companions, sometimes even calling him by name. Often these voices lure him away from the path and he never finds it again, and many travelers have got lost and died because of this.
