GEOG 121 (Planet Earth: Surface Processes and Interactions), Lab 2-2 Western Illinois University Part 1: Short Answers Q.1. What is the relationship between seafloor spreading and reversals in Earth's magnetic field? The beginning of seafloor spreading from plate tectonics was generated by Alfred Wegener in 1912. The process of magnetic reversal was proposed by Harry Hess in 1962. In this the relationship between the seafloor spreading and the reversal in Earth’s magnetic field new ocean crust forms. As tectonic plates move apart magma can rise to create a band over the ridge. This forms because of the rich minerals align themselves with Earth’s magnetic field. More magnetic fields form altering the ocean floor even more. During this process, the ocean floor ends up having a varying band of rock. This can be reversed because of the magnetic polarity. Scientists throughout the years can study the different magnetic stripes and determine what rate the seafloor is spreading and the abnormalities, and can reconstruct the entire timeline of the ocean floor. Studying these helps determine the age and factors in plate tectonics through the years. Q.2. Describe the endogenic and exogenic processes involved in the geologic cycle. In the geologic cycle, there is an endogenic and exogenic process. In the exogenic process or internal processes, there is weathering, erosion, deposition, chemical weathering and sedimentation. These processes occur near the Earth’s surface. They can result in the deposition of the many materials that shape the land. This can mean that they are the cause of many valleys, beaches, sand dunes, and rivers. Many people will experience first hand the damages from endogenic forces. Exogenic forces are different. They take thousands or millions of years to occur. This could be an Earthquake taking forever to occur or a Volcano erupting after thousands of years. Q.3. List some examples of anthropogenic endogenic and exogenic processes in the geologic cycle. In the anthropogenic activites are mining, smelting, hydraulic fracturing incineration of fossil fuel, etc. In the mining process, the land is destroyed due to the creation of tunnels, large open holes, and other altered structures and lands. They have faulting, magma intrusions, plate tectonics, and folding in the endogenic process. In the folding process, rocks are compressed, leading to other rocks' folding and compression. In the faulting process, there are movements in the Earth that can cause different issues such as earthquakes. In magma intrusions, tthe earth's crusthas melted molten rock that protrudes into the surface. With plate tectonics, the plates can move and shift together resulting in volcanoes erupting, earthquakes, and mountain ranges being formed. In the exogenic process there is erosion, sedimentation, glacier activity, sedimentation, and coastal processes. Erosion is the shaping of Earth’s surface. It is the wearing of rock, soil, and sediment through a natural process. It is the reason why soil and rock move. This can be caused by glaciers, ice or water, and wind. 3/5

GEOG 121 (Planet Earth: Surface Processes and Interactions), Lab 2-2 Western Illinois University Q.4. Choose three plate tectonic-related landforms that can be identified on satellite images and describe them in detail. A: Colorado Plateau- The Colorado Plateau is a plateau that is surrounded by different features such as high mountains, rivers, shallow basins, deserts, and mesas as many plateaus that are of flat lying. The plateaus and rocks are multi colored sedimentary rocks built into the mesas. The rocks are red, gray, white, yellow, and green. These features ale came about from the tettectonic uplift and the erosin from the Colorado River. In pictures, you can see sparse vegetation. B: Himalayas- The Himalayan Mountains are a mountain range in Asia. It is lifted by the subduction of the Indian tectonic plate under the Eurasian Plate. The highest point is Mt. Everest. The Himalayas are known for being the highest mountains in the world and having steep heights, steep jagged peaks, alpine glaciers, many deep rivers, and elevation belts. It has 19 different rivers running through it. C: Appalachians- The Appalachian Mountains are a mountain range based in eastern United States that formed 400 milion years ago. These mountains have been worn down from wind and water from erosion. They consist of rolling hills, the Smokey Mountains, the Cumberland Mountains, the Blue Ridge Mountains, and the Allegheny mountains. They also have the Appalachian Plateau and the Cumberland Plateau. There are many steep slopes from mountains, gorges, valleys, ridges and a variety of different plants and trees. The mountain appears to be striped on a map because the variety of crops and the different plants that cover parts of the mountains. Q.5. Using the figure below, identify the following terms. 4/5

GEOG 121 (Planet Earth: Surface Processes and Interactions), Lab 2-2 Western Illinois University Explain this particular plate-tectonic-related landform in as much detail as possible. Colorado Plateau was formed 70 to 40 million years ago by tectonic plates diving under the inland of North America. The Laramide Orogeny was generated. This event caused uplifted mountains such as the Rocky Mountains and volcanos. It left it mostly undeformed making it a flat lying plateau made out of sedimentary rock. Now it is a colorful flat lying plateau with layers among layers of sedimentary rock. These rock layers are made out of sandstone, shale, limestone and siltstone The formation of the plateau lead to the creation of the Colorado River as well. There 9/5

The Himalayas are the largest mountain in the world. This mountain consists of Mount Everest, the highest point on Earth. It has several glaciers, valleys, gorges, and canyon like formations. It was formed by the collison of the Indian and Eurasian plate. This is called the Subduction zone. These plates were having activity for millions and millions of years. The Indian Plate sunk beneath the Eurasian Plate. When it sunk it moved forward and the plate began to buckle. They are still buckling every year because the plates are still moving and uplifting. The ecosystem is very valuable there from all of the 11/5

GEOG 121 (Planet Earth: Surface Processes and Interactions), Lab 2-2 Western Illinois University Explain this particular plate-tectonic-related landform in as much detail as possible. The Appalachians were formed by the Earth’s lithospheric plate and has played a role into the theory of plate tectonics. Erosion from water and ice has also helped shaped the mountains and have created steep ridges and valleys. Today these mountains still have mini earthquakes. They experienced millions of years of erosion but the plates have continued to have a slow uplift. They consist of sedimentary rocks and metamorphic rocks. This created a more rugged topography. The Appalachians exhibit many high peaks, hills, plateaus, and valleys. The Great Smoky Mountains with an elevation of 6,643 feet are one of the major points of the 13/5
