These currents could move continents laterally along the earth’s surface. Paleomagnetism further backs this up, it shows that the positions of magnetic north for 200million year old rock in different continents
The evidence of sea floor spreading was further supported by Vine and Drummond, who studied the magnetic pattern of the sea floor. They found that the Earth’s magnetic field changes over time, because as magma from the mantle rises to the crust it cools but the basalt will align to the field it cools to. It is also found that on either side of mid oceanic ridges there were symmetrical magnetic patterns, so suggesting that the ocean was created at the mid oceanic ridges and as new ocean floor cooled, it pushed the crust away. Both Hess and Vine and Drummond found evidence that is crucial to the explanation of how continental drift happened, and it is very important in the development of geologists understanding, however other people found evidence to support continental drift also. Dan McKenzie went on to further explain sea floor spreading, being able to explain why new crust was made at mid oceanic ridges.
After reading these two articles I found out that there are a lot of similarities and differences bin these two articles. The greenhouse affect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric gases, the gases we produce and put in the air everyday. Also they both had a plan for trying to get to know the future outcome of the weather due to past weather conditions. They find out from ash particles found in ice or measuring the sea level,seeing if it has risen from polar ice caps melting. One more similarity is the equipment they used to get the results for example they both used temperatureDetermining global warming effects on weather can be done in many different in these two articles I found that you can use ice or water.
An example of catastrophism is an earthquake. This is an example of catastrophism because it shows a sudden change. Uniformitarianism is the principle that states the geological processes that happened earlier in history can be explained by the geological processes that are happening gradually today. This principle is what people began to consider shaped the Earth. An example of uniformitarianism is when rock wears away and erodes.
-”Wegner used the shapes of matching shorelines on different continents as a supporting piece of evidence for continental drift. 3. Describe Earth's magnetic field, including how it has changed through time. -Similar to a simple bar magnet, ends have opposite polarities that cause magnetic objects to align parallel to it’s magnetic field. Poles have wandered from geographical position over the years.
These are important to prove evolution. Convergent evolution includes three very important parts: (a) common ancestry, (b) speciation, and (c) natural selection. Evidence of a continental drift involvesis marsupials spreading across oceans that did not yet exist, making their travel across vast bodies of land possible. A key examplenother supporter of the a species that experienced continental drift is the Glossopteris. This tree was only able to grow in warm climates and had a seed that could not float, yet fossils of this tree are found in different hemispheres of the world today.
Assess the strength of relationship between tectonic processes and major landforms at the Earth’s surface. There is a range of evidence to suggest there is a strong relationship between tectonic processes and major landforms at the Earth’s surface due to, for example, the presence of volcanoes, fold mountains, trenches, and ridges. Tectonic processes include, divergence, which is when plates move away from each other, convergence, when plates move toward each other and collide, Subduction zones, which occur where an oceanic plate meets a continental plate and is pushed underneath, Obduction, which occurs when the continental plate is pushed under the oceanic plate, and collision boundaries, which occur where two continental plates collide and push upwards to form large mountain ranges. However this evidence is weakened by the process of weathering and erosion, due to the presence of the Grand Canyon, one of the Earth’s major landforms. As well as landforms caused by river processes, such as the Bangladesh Delta – which can be seen via satellite - therefore a major landform.
3. Perform independent research to answer the following questions: Cite resources used o A. What was the size or tons of the object that impacted Earth during the late Mesozoic – often given credit for causing the dinosaur extinction? Discuss where the impact occurred, what size crater was produced, how fast it was traveling, and how did this event impact the Earth? o B.
Where is the park located and what are its' dimensions? The base of the Cascade Range was constructed as the Earth's crust folded and uplifted, pushing the seas westward. Molten rock pushed toward the surface, creating both violent eruptions and forcing an incredible amount of lava upward through enormous cracks. Within the past 750,000 years these explosive eruptions built a string of volcanoes on this plateau base. This Cascade Range of volcanoes extends from Canada's Mount Garibaldi to Lassen Peak in northern California.
Geologically, Aruba is more complex. The geological formation of Aruba’s geography is composed of three major rock groups; Igneous, metamorphic and sedimentary. To the reader who just looks at the textbook, this means that Aruba (the Island) was there long before the late 15th century when the Spanish first came here. Actually, Aruba was formed from the process of volcanism some 90-95 million years ago. The Island of Aruba is the result of lava hardening from a volcano that occurred almost 100 million years ago underwater.
