Plate tectonics stands as a foundational theory in geology, encapsulating the dynamic processes responsible for shaping Earth’s surface features over geological time scales. Originating from the groundbreaking work of scientists like Alfred Wegener and Harry Hess, the theory posits that the Earth’s lithosphere comprises rigid plates that interact along boundaries, giving rise to diverse geological phenomena. These boundaries, classified into divergent, convergent, and transform types, serve as zones of intense geological activity where tectonic forces manifest in various forms. At divergent boundaries, such as mid-ocean ridges, magma upwelling leads to seafloor spreading, creating new crust and geological features like rift valleys. In contrast, convergent boundaries witness the collision and subduction of plates, resulting in volcanic arcs, mountain ranges, and seismic events characteristic of subduction zones. Transform boundaries, like the San Andreas Fault, accommodate horizontal motion between plates, generating earthquakes and faulting. The resultant tectonic landforms, ranging from the Mid-Atlantic Ridge to the Ring of Fire and the Himalayas, offer tangible evidence of plate tectonics’ profound influence on the Earth’s surface. Continental drift, a central tenet of plate tectonics, has driven the assembly and dispersal of supercontinents, influencing global climate patterns, ocean circulation, and biological evolution. Moreover, plate tectonics holds significant practical implications, informing natural resource exploration, hazard assessment, and environmental management efforts. Geological studies of plate boundaries provide crucial insights into mineral resources, hydrocarbon reserves, and seismic hazards, guiding land-use planning and disaster preparedness measures. Overall, plate tectonics stands as a cornerstone of geology, illuminating the dynamic processes that have sculpted Earth’s landscapes and continue to shape its geological evolution.

This exercise is meant to help you visualize the vastness of geologic time since Earth’s
formation, ~4.6 billion years ago. It is difficult for us to imagine the amount of time required for
many geological processes to occur (e.g., formation of oceans or mountain ranges). The geologic
time scale organizes the Earth’s history into a series of chronologic subdivisions that are defined
by important geologic events in the Earth’s history. The largest of these time subdivisions are
eons. Eons are then subdivided into eras. Eras are subdivided into periods, and periods are
subdivided into epochs. We currently live in the Holocene epoch of the Quaternary period in
the Cenozoic Era of geologic time. Once you have finished this exercise, you will realize what a
tiny slice of time that represents relative to the vastness of geologic history. this assignment requires a PowerPoint and answer the questions.
please be creative when creating the PowerPoint.

GRAND TETON NATIONAL PARK IS MY PARK WHICH LEADS US TO A MAP OF JENNY LAKE I WILL ATTACH BELOW
Objective of the assignment: To further understanding of concepts in the topographic maps unit, as well as allow students to begin work on their final project by having them select a topic and begin basic research of their chosen location. Contribution to the final project: The work conducted in this assignment will be used as part of a larger, comprehensive presentation of the geology of a national park. Specifically, this assignment will have students choose their location and conduct research on the geologic setting of that location through the use of topographic maps.
Background: *You should have completed reviewing all lecture materials before attempting to complete this assignment*
In order to understand and interpret the geology of an area, you must first gain a better understanding of the landscape itself. What does the landscape look like? Is it characterized by one large feature such as a volcano or a canyon? Is it characterized by the presence of sinkholes and caves? By mountains and valleys shaped by stream systems? The character of a location can be described when the topography of that location is described. In order to describe topography, you must know something about reading a topographic map. BEFORE YOU DO ANYTHING ELSE, YOU MUST POST YOUR CHOSEN LOCATION ON THE DESIGNATED DISCUSSION BOARD. Every student must conduct research on a unique location, meaning that there should not be a repeat of topics for anyone in the class. To make sure everyone has selected a unique location, students must post the location of their choice on the class discussion board. You will choose the national park you would like to do your project on from the list included on the final project instructions. Make sure to read through the discussion board to see if someone has already chosen the location you have picked. If the location is already chosen, you need to choose another (it is best to have 2 or 3 locations picked out in your mind before going to the discussion board). Location selection is first come, first serve. Once you have selected your location, and “claimed” it by posting on the class discussion board, write in the national park you chose in the space below. GRAND TETON NATIONAL PARK
Part 2: Obtaining a Topographic Map
The United States Geological Survey (USGS) has a database called topoView that keeps all topographic maps created since the USGS began mapping the nation’s topography in 1879. As the landscape has changed, maps have been updated, and many have been created at different scales to show different features of the landscape for different purposes. The topographic map you will need for your project should be the most recent version of the map in your location and should be at a scale of 1:24000 to show you the features you will need to report on. Follow the instructions to obtain your map for your project (and feel free to repeat this process for acquiring any map you may want in the future!).
Go to the USGS topoView website by following this link: https://ngmdb.usgs.gov/topoview/
Along the right side of the page there is a red button with mountains and contour lines that says “View and Download maps now”. Click the button. This will take you to a new page with a map of the US on the left and a search box on the right. You may read over the Getting Started instructions if you need them.
In the search box at the top right of the page, enter the name of your national park. A dropdown box will appear with a location. Click the location. Depending on your park, there may be more than one location listed, as your park may span across several topographic quadrangles. That is ok; you may browse through these selections and pick the area you would like to use. If you only have one location choice, pick that one. Once your location has been selected, you will see a number of map choices listed. These are all of the maps, young and old, at different scales, that have been created for your location. Scroll down to the bottom to find the most recent map at a 1:24000 scale. Click that selection.
Once selected, several buttons will appear: file types, zoom options, an info button, etc. There will be 4 file types offered: JPEG, GeoTiff, KMZ, and a GeoPDF. A JPEG will be a low resolution picture of the map, the GeoTiff file will generally be a storage tool for satellite and aerial imagery data, the KMZ file will open with Google Earth and have map information overlayed onto an interactive Google Earth landscape, and the GeoPDF will be a high resolution image of the map that will allow you to zoom in and see features on the map without you having to print a large quadrangle. For this exercise, you will need to download the JPEG file and the GeoPDF of your location.
Part 3: Making Geologic Observations using your Topographic Map
1)Open your downloaded JPEG image. This is the smallest file type of your topographic map, and should therefore be easy to include in this document and keep this document a reasonable file size. Copy and paste this image into the space below so your instructor can see the map you are working with. Resize it to fit on the page and choose to wrap the text Top and Bottom to prevent any overlap of your image with your text. Use the GeoPDF to answer the remaining questions.
2) What is the name of your chosen quadrangle? Jenny Lake
3)What are the latitude coordinates along the northern border of this map?
4)What are the longitude coordinates along the northern border of this map?
5)What is the contour interval of this map? How do you know?
6)List 3 major topographic features you see on your map. For each, describe how you know what the feature is on the map. Remember that a topographic feature can include, but is not limited to, mountains, valleys, depressions, ridges, streams, volcanoes, canyons, lakes, etc.
7)Look carefully over your map and pick out a major stream on the map. Write the stream name, describe its direction of streamflow, and how you know what direction it is flowing.
8)Look over your map carefully and find an area where the topography changes. Using a 5-inch-wide sheet of scrap paper, make tick marks along the contour lines and write in the elevations in this area. This will give you the information you need to create a topographic profile. You may need to complete the lab in this unit before you attempt to create a profile here so you can gain a better understanding for drawing a topographic profile. Once you have the information you need, draw a topographic profile of your area on the grid below
9)Reviewing your answers from questions 6 and 7, and looking at your profile from 8, summarize the topography of your topographic map. To do this, you will need to describe the character of the landscape, as observed by behavior of the contour lines on the map, as well as note how other features may occur on your map.9)Look over your map carefully and find an area where the topography changes.

Once you have the information you need, draw a topographic profile of your area on the grid below.
10)Finally, using what you have learned through this activity, briefly describe the geologic setting this topographic area is in and how that has contributed to the features you observe on the topographic map. To do this, you may want to discuss rock type and/or tectonic setting and how each may contribute to what you are observing. To get to know more about the geologic setting of your area, you may also want to conduct some additional research using your national park’s website, the general national park website, the USGS website, or another credible source of geologic information. Cite any additional sources used to help you with your answer.

1. List all the coordinates that defined the stops for your group’s ocean voyage project and map them on this World Map. Options: You may print a hard copy and legibly plot them with pen or pencil OR you may go to the File Menu in GoogleSlides to Make a Copy for yourself to edit and add points by inserting shapes and labeling them with text boxes. Knowing what you now know about global wind and current patterns, discuss whether your route as originally planned would maximize efficiencies by utilizing assistive power from winds/currents. If you find that your originally proposed route has your ship fighting against the wind and currents a lot, use your knowledge to propose a different route. You can specify any starting position and any end position, but you must still pass by all of the stops in between. Draw arrows on your map to show the most efficient route that you determined. Name the specific winds and currents that you will make use of along this route. I will post the world map as a file. 2.Compare and contrast the continents and the seafloor with respect to: topography, crustal rock type, age, density and thickness. Use a drawing to explain the significance of these observations to plate tectonic theory. For this one there is no specific image, you need to do everything, by yourself.

Attached is your first major lab exercise on plate tectonics. I have provided it in both Word and pdf formats. A convenient resource will be a virtual textbook for which I have forwarded a link in an announcement. You will need to print the labs out and complete them and then submit using your Microsoft Lens app. They do not have to be in color. I will have black and white copies in room 268 of the SET building if you are local to the UNA campus. If you are unable to print the assignments out, let me know and I will arrange for you to get it. A small portion of the lab requires the use of tracing film. You can just as easily use a piece of copy paper.(I will put some tracing film in the shelves next to the left side door along with the lab copies…Only one per person!). I am on campus Monday and Tuesday evenings and I am frequently there on Saturday or Sunday afternoons and as such, I can give you some assistance and/or provide materials. Just let me know. Since I am an adjunct professor, and I do not spend a lot of time on campus, if you have issues, send me an email at dbmarkham60@gmail.com or feel free to text me at 256-627-4909.
