Alfred Lothar Wegener was born on November 1, 1880 and earned a Ph.D in astronomy in 1904. However Wegener had always been fascinated in climatology and meteorology. (According to ucmp.berkeley.edu) In the autumn of 1911, Wegener was browsing in Marburg university’s library and found a scientific paper that listed fossils of identical animals and plants found on opposite sides of the Atlantic ocean. With further searching he was able to prove that his theory of “Continental Drift” could have been true. The continental drift explained how parts of Earths crust could slowly drift atop a liquid core causing all continents were once formed as a single landmass to split apart . Although Wegener was the not the first scientist that all continents were connected at some point of time but, he was the first to prove it was plausible with evidence. This is why I agree that the continental drift is true, because of the fact that there were fossils of the same organisms on opposites sides of the Atlantic, same rock strata of South Africa and Brazil, and that fossils found in certain areas could ...
Charles Lyell was a British lawyer and one the smartest geologist known in his time. He was known as the author of the Principles of Geology, which helped popularize the theories and concepts of uniformitarianism. The Principles of Geology was the first book written by Lyell and explained the changes of the earth’s surface. He used the research and information in the book as his proof to determine that the earth was over 6,000 years old. The central argument in his book was “the present is the key to the past”, this meant that to find out what happened in the past you had to look at what was happening now. It explained that changes which happened in the past, were happening in the present, and will happen in the future. Lyell’s book was later published into three volumes from 1830-1833. After the publication, it gave him credentials as an important geological theorist. His book later influenced a young Charles Darwin. Lyell’s influential book led Darwin to follow his principles and they later became friends. Darwin began to explore the changes that happen on the earth and develop his theories of evolution, though Charles did not completely endorse Darwin’s theory of evolution. Lyell was a devout Christian and Darwin’s theory of evolution did not line up with his Lyell’s beliefs with natural selection. Darwin continued his research and beliefs of his own and became a scientist working with his theories of evolution.
For example when he writes about how the axes of each continent affects how well ideas and domesticated crops and animals flow or spread through the continent. This discussion had made lots of sense for me and is yet another idea that supports his theory. "At the one extreme was its rapid spread along east-west axes: from Southwest Asia both west to Europe and Egypt and east to the Indus Valley (at an average rate of about 0.7 miles per year); At the opposite extreme was its slow spread along north-south axes: at less than 0.5 miles per year, from Mexico northward to the U.S. Southwest; at less than 0.3 miles per year, " This example shows how east to west axes allow for a faster diffusion of crops and animals. But the north to south is very slow compared to the other. This helps explain why Eurasia had developed the quickest and the America and Africa lagged behind." For example, Portugal, northern Iran, and Japan, all located at about the same latitude but lying successively 4,000 miles east or west of each other, are more similar to each other in climate than each is to a location lying even a mere 1,000 miles due south." This line tells us why Eurasia was able to develop so fast. That is because it has an east to west axes which means animals and crops can more wildly thought the same land due to there being large amounts of land with the same latitude. While the Americas
He began writing about his hypothesis/ idea in 1864-65, and published the results in 1866. It was not until 1900 that his published findings were
The approach to climate change has been a topic of debate for as long as the concept of climate change has been around. Some believe that the Hamiltonian response, a focused national response from the government, is necessary in order to get the country to correctly react to the problems the world is currently and will be facing. Others believe that the Jeffersonian response is more appropriate since it means that citizens would be in control of the changes and therefore more willing to make the changes and more likely to accept, follow, and tell others about these changes. However, to truly implement the kind of change necessary to combat climate change, a mixed approach is necessary to not only ensure that a larger portion of people want to follow the changes, but also ensures that the changes are practical and efficient. Any extremes in the matter will result in a large portion of people not taking the matter seriously or only affect a specific group of people. So why is neither response alone the right response and where should the government's control end and the people's begin in order to create the most effective response to climate change?
The team of Tycho Brahe and John Keppler were the next to study Copernicus’ theory. Brahe tried to disprove Copernicus’ theory and tried to prove the idea of the earth-centered universe. Although Keppler was Brahe’s assistant, he argued for Copernicus and analyzed Brahe’s data to conclude that the sun was the center of the universe. Keppler also used Brahe’s data to discover the movement of the planet Mars. This was the key to explaining all planetary motion. ii He also discovered the planets move in elliptical orbits, which also went against the beliefs of the church. Kepp...
Charles Lyell was born on November 14, 1797 at Forfarshire, Scotland. He was a Scottish lawyer, a geologist as well as a supporter of Uniformitarianism. He was the author of Principles of Geology. His theory was that earth must be very old and that throughout time the planet has undergone processes that change the shape the land. That includes erosion, earthquakes, glacial movements, volcanoes, and the decomposition of dead plants and animals.
Charles Darwin was a scientist from the United Kingdom who was a naturalist and geologist in the early 1800s. Although, he is best known for his role in the evolution theory. Darwin decided to take part in a five-year voyage in 1831, called the Beagle, to make naval charts of South America. At the beginning of the expedition Darwin was just a young graduate, at the age of twenty-two, with only eagerness to be able to be a part of the opportunity. He had no high expectations to find the rare discoveries that he had found during his time on land on the far off continent. By the end of the excursion, Darwin had made a name for himself as a geologist and fossil collector after his journal was published, later titled The Voyage of the Beagle. His writing got him a lot of attention from multiple scientists around the world.
He just had a theory, but know facts. When coming up with this idea of plate tectonics, he used many different tools. He used fossils, different rock types, and a bunch of climatic evidence. Henry hess came up with the idea of seafloor spreading( the oceanic plates spreading and moving
The impact these men had on religious thought was tremendous. Some of them are the starting points for many of the controversies existing today. Of all the scientists, historians, and philosophers in the nineteenth century, the most influential and controversial was Charles Darwin. Born in 1809, Charles Darwin always had an interest in the nature, so he chose to study botany in college. His strengths in botany led him to become the naturalist on the H.M.S. Beagle. On a trip to South America, he and the rest of the crew visited the near by Galapagos Islands in the Pacific Ocean. It was there he noticed many different variations of the same general plants and birdshe saw previously in South America. He also observed ancient fossils of extinct organisms that closely resembled modern organisms. By 1859, all of these observations inspired him to write down his theories. He wanted to explain how evolution had occurred through a process called natural selection. In his published work, On the Origin of the Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life, or On the Origin of Species for short, Darwin stated that, "new species have come on the stage slowly and at successive intervals."(1) He also said, "old forms are supplanted by new and improved forms," and all organisms play a part in the "struggle for life.
A change in global or regional climate patterns, a change which was noticed during the mid 20th century due to excessive use of fossil fuels.
Our world is always changing, so is our climate. Some changes are apparent, others not so much. Climate change is an important issue of concern in the twenty-first century. Environment, if it changes at all, evolves so slowly that the difference cannot be seen in a human lifetime (Wearth, 2014). Mostly all scientists predicted that it would take thousands of years for the planet to warm up due to emissions of carbon dioxide from fossil fuels called greenhouse gases. But in the past 200 years, things began to change. The rate and the amount of warming that is happening on this planet are unprecedented. Wearth says, “People did not grasp the prodigious fact that both population and industrialization were exploding in a pattern of exponential
Climate change has become of the world’s major issue today. The earth’s climate is always changing in a very fast and also in different ways. Climate changes affect our lives psychologically, emotional and also physically. Climate change is defined as a long term change in the earth’s climate, especially a change due to the increase in the average atmospheric temperatures. Due to this change in temperature, a lot of changes has occurred in our environment, these changes include rising sea levels, flooding, melting of polar ice caps, hotter days, colder nights and heat waves. These climate changes plays an important role in shaping our natural ecosystem, our human economics and also the most important, it affects the human race. For
Of all the scientists to emerge from the nineteenth and twentieth centuries there is one whose name is known by almost all living people. While most of these do not understand this mans work, everyone knows that his impact on the world is astonishing.
Charles Darwin’s theory of evolution took years and years of research. Throughout these years he found different people who were also interested in this phenomena and had them join him in the study. Before Charles conducted his research he looked back in time to other scientists who wrote about this theory. Aristotle, a Greek philosopher, believed there were natural laws in how the world came to be. “He believed that there were “higher” species and also “lower” species, and the lower ones gave rise to the higher” (Rosenberger 3). He believed against the usual myths about how the universe came to be and had similar ideas to Darwin. In 1831, Charles was asked by Capt. Robert Fitz-Roy to set sail on the H. M. S. Beagle, which sailed around the world. “Charles was to record information about the geology,...
Science is about understanding and building knowledge about how the natural world works. It explains the inter-relationship with one's life and nature and promotes environmental education and more so environmental habits. Science teaches us as learners’ important skills such as reasoning, problem solving, analyzing, predicting, etc. It builds a foundation by providing a base in case a child does not go to higher level of education. Since science is all around us it is important to teach it so that the children could learn about themselves and their environment. Science also provides the knowledge needed to create new pieces of technology, which scientists used to develop civilization. For example, rather than writing
