In 1912 Alfred Wegener A German Meteorologist And Geophysicist Outl ✓ Solved

In 1912, Alfred Wegener, a German meteorologist and geophysicist, outlined his hypothesis for "continental drift." This hypothesis challenged a long-held assumption that the continents and ocean basins had fixed geographic positions (i.e., they didn't move). Explain the continental drift hypothesis. Describe two lines of evidence Wegener used to support his continental drift hypothesis. What was the main flaw with Wegener's continental drift hypothesis? Your essay must be in your own words.

Instructions ： Use standard essay format (topic sentence, supporting information, conclusion). It should be about words - roughly one page (front only) hand written. will be graded on content, grammar, punctuation, and flow. Read your draft out loud to yourself - does it make sense? It should sound like a written document, not like a conversation. We will spot check for cheating - we are really good at spotting material that has simply been copied from the web.

If we catch you turning in plagiarized material we will report it to the Dean of students office as cheating and you will receive a 0 on the writing. Feel free to draft your answer outside of class and bring it with you to class on writing day. You will not be allowed to turn in your draft, but can "transfer" it to the paper we hand out.

Instructions and guidelines: You can do research outside of class, write/prepare notes and/or a draft to bring to class 16 Feb. ABSOLUTELY NO ELECTRONICS CAN BE USED DURING THIS!

Writing will happen in class 21st September - you cannot turn the writing in before or after 21st September in class. You cannot email it to me. During in class writing you will get a piece of paper on which to complete your writing. Writing must fit on the front of the page - anything on the back will not be read. Write in complete sentences.

Answer all parts of the question (this one has three questions you need to answer - read the prompt carefully. Use enough examples). Use standard essay format (topic sentence, supporting information, conclusion). It should be about words - roughly one page (front only) hand written. You will be graded on content, grammar, punctuation, and flow.

Read your draft out loud to yourself - does it make sense? It should sound like a written document, not like a conversation. Grades are out of 10 pts. You will automatically get half credit (5 pts) if you come to class and participate in the writing, provided you write something that is related to the topic. Grades go up from there based on quality of the writing and accuracy of the content.

6 pts = D, 7 pts = C, 8 pts = B, 9 pts = A, 10 pts = PERFECT! See posted rubric for more specifics about grading. If we cannot read your handwriting you will automatically get a 5 (no higher). We will spot check for cheating - we are really good at spotting material that has simply been copied from the web. If we catch you turning in plagiarized material we will report it to the Dean of students office as cheating and you will receive a 0 on the writing.

Feel free to draft your answer outside of class and bring it with you to class on writing day. You will not be allowed to turn in your draft, but can "transfer" it to the paper we hand out. We encourage you to make an appointment via email to bring your draft to Dr. P or a TA for feedback prior to writing day. You cannot email your draft to us for feedback - you must meet with someone for feedback.

The only way to ensure a good score is to get feedback on your draft PRIOR to turning in your final version. Please don't wait until the Wednesday before the writing is due to make an appointment. Chances are you will not get one.

The Continental Drift Hypothesis: A Historical Perspective
In 1912, Alfred Wegener, a German meteorologist and geophysicist, introduced the revolutionary hypothesis of "continental drift," which postulated that the continents were not static but had instead drifted over geological time to their present positions. This notion challenged the static view of Earth's continents and ocean basins as fixed geographic entities, thereby offering a new perspective on the dynamic nature of Earth's surface. Wegener's hypothesis arose from his keen observations of various geological and biological patterns that presented compelling evidence for the movement of continents.
One of the most significant lines of evidence supporting Wegener's hypothesis was the fit of the continents, particularly the snug alignment of the eastern coastline of South America with the western coastline of Africa. Wegener illustrated the similarity in shapes and suggested that these landmasses were once part of a larger supercontinent he termed "Pangaea," which existed approximately 300 million years ago. This concept better explained the geological similarities between widely separated landmasses, as identical rock formations and fossilized remains of flora and fauna were found across these boundaries (Stern, 2018). For instance, fossils of the freshwater reptile Mesosaurus have been discovered in both South America and Africa, despite the vast Atlantic Ocean separating these continents today (Nance et al., 2014). Such evidence suggested that these regions were once united, further solidifying the argument for continental drift.
Another line of evidence presented by Wegener was the geological and climatic similarities observed in regions now located on different continents. For example, the Appalachian Mountains in North America share striking similarities with the Caledonian Mountains in Scotland and the mountains in Scandinavia (Wegener, 1915). This geological linkage suggested a connected geological history that could only be explained through a previous union of these landmasses. Furthermore, fossil evidence indicated that the climate in regions such as Antarctica was once much warmer, supporting the idea that these continents have moved from their original equatorial positions to their current polar locations (Wegener, 1915). The distribution of coal deposits, which form in warm, humid climates, in regions like northern Europe and North America, serves as additional evidence that these areas were once part of a tropical region before drift occurred (Müller et al., 2016).
However, despite the compelling evidence, Wegener's continental drift hypothesis was met with skepticism primarily due to its main flaw: the lack of a viable mechanism to explain how continents could drift apart. While Wegener proposed that forces such as Earth's rotation and tidal movements might exert enough pressure for continental movement, these explanations were not scientifically robust and could not adequately account for the observed geological phenomena (Cox & Hart, 2019). Thus, without a credible force behind the movement of continents, his theory encountered significant resistance from the scientific community of his time, which largely adhered to the static view of Earth's crust.
In conclusion, Alfred Wegener's continental drift hypothesis represented a groundbreaking shift in earth sciences that challenged traditional geological views. His observations regarding the fit of continents and analogous geological features provided substantial evidence for the theory. However, the inability to propose a credible mechanism for the movement of continents ultimately undermined his hypothesis. It wasn't until the development of the theory of plate tectonics in the 1960s, which explained continental movement via the dynamics of tectonic plates, that Wegener's ideas gained widespread acceptance and recognition. Today, his work is respected as a precursor to modern geology and a critical step toward understanding the complex behavior of Earth's lithosphere.
