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.
In this assignment, you’ll learn to find soil data for the continental United St
In this assignment, you’ll learn to find soil data for the continental United States using the USDA’s Soil Survey. The soil survey is used for many different practical applications, including wetland assessment and delineation. So, let’s explore the soil survey.
Step One: Launch the Soil Survey
Navigate to the Soil Survey https://websoilsurvey.sc.egov.usda.gov/App/WebSoilSurvey.aspLinks to an external site.
You should see a map of the continental U.S.
On the left, you should see a Menu with ‘Quick Navigation’ that will allow you to search by address, county, and so forth.
Above the map you should see a title ‘Area of Interest Interactive Map’; Below that title you should see a set of tools for interacting with the map (zoom, pan, AOI, etc).
If you’ve found those items on the page, then continue to the next step. (picture uploaded 1)
Step Two: Delineate an Area of Interest
Select a wetland of interest contained in the map. The wetland should be located in Okeechobee County, Florida.
Zoom into that location. You can use either the interactive tools (e.g. zoom, pan) or the quick navigation tools (e.g. address or county) to navigate to your location.
Delineate an area of interest around the wetland using the AOI tool (there are rectangular and polygon tools in the tool bar (they say AOI above a red shape) by using the cursor to draw around your area.
Once you’ve successfully created your AOI, it will appear outlined in aqua like below.
If you need to redraw your AOI, just click ‘Clear AOI’ on the AOI Properties menu that you’ll see on the left, and try again.
One you’re satisfied with the AOI, move to the next step.
Step Three: Explore the Soils DataNear the top of the page, click on the red tab labelled ‘Soil Map’. If you get an error saying data in unavailable, you’ll need to redraw your AOI until you find one with availability.
Your mapped view should now show polygons delineating different soil map units. These map units cover areas of similar soils.
On the left, you’ll see a list of the soil map units in your AOI. The list will be in table form and include: Map Unit Symbol, Map Unit Name, Acres in AOI, and Percent of AOI.
Click on one of the names. You should then see a window pop up with information about that map unit. You’ll see what soil types are present (sometimes there are more than one) and which is the most dominant.
You can also click the ‘i’ icon from the map tools to load the information tool, and then click on an area of your AOI. This will give you a quick description of the soil, but not the full details in the pop-up window.
Take a few minutes to look at the kind of data recorded in the soil survey for your AOI.
Once you’re satisfied in how to navigate the data, move on to the next step. (picture uploaded 2)
Step Four: Describe the Soils for your AOI(1) What were the two most common map units in your AOI? Provide their names and acreage.(2) Choose any one of the map units that you found interesting. Provide a description of one of its components (e.g. 5—Felda fine sand, 0 to 2 percent slopes), including:Soil type name
Landform
Drainage class
Frequency of flooding
Other vegetative classification
Hydric Soils rating
Description of the Soil Profile (depth and texture of each horizons). Note: in this class, we simplify soil profiles. For example, you may see an E horizon, which is a mineral horizon in the upper part of the soil that is typically only present in forested areas. Or, you may see subscripts to the letters (like Btg) which you can ignore
Step Five: Did you know that you can also download soils data from the Soil Survey? This would be useful if you want to map the soils in a geographic information system. We won’t do that in this course, but to do so, you would click on the red tab labelled ‘Download Soils Data’, click ‘Create Download Link’ at the bottom, and then save the .zip folder to your computer.

this is a question on Geochemistry. I’ve answered the question but my answer was wrong and I got this feedback from my teacher so I would be grateful if you could help me solve it correctly with an explanation. this is my answer and the feedback. please do not use AI or Chegg to answer the question because they provide wrong answers.
The question :
the calculation of the Sm/Nd elemental ratio of the depleted upper mantle
and continental crust, assuming the depleted mantle 143Nd/144Nd = 0.5131 and
Continental Crust (CC) 143Nd/144Nd = 0.5118, and age of extraction from CHUR
=2.5 billion years.
The feedback:
:You use the chondritic earth values to calculate what the initial 143/144Nd is at 2.5 Ga. Then, since both mantle and crust started from that point, that point becomes your 143/144Nd(o).
So now, you know your initial [143/144Nd(o)], and you know present day MORB (0.5131) and Crust (0.5118). The only unknown you have left in the equation is the 147Sm/144Nd of DMM and Crust reservoirs. Solve for that, and then you calculate from the parent daughter ratio the elemental Sm/Nd ratio. You cannot have the same Sm/Nd answer for both DMM and Crust; they are different reservoirs.
The progression from minerals to igneous rocks is natural owing to the environme
The progression from minerals to igneous rocks is natural owing to the environments of formation associated with cooling magma and associated hydrothermal (hot water) activities. In this lab, you will definitely need to read the lab activity as you answer the questions. A certain amount of knowledge concerning mineral types/groups is necessary as well, not only in this lab, but the next two as well.
You may submit the answer sheets at the end of the exercise in lieu of the entire copy or (preferably) use a single numbered sheet of paper to cut back on paper usage. Submit using Microsoft Lens by the deadline. By doing it this way, we can restrict the usage to only one sheet of paper. However, if anyone needs them, I will leave paper copies of the lab in Rm 268 of the Science and Engineering Technology Bldg.
1. Watch the
Video:
1. Watch the video above titled Earth Systems Interact to learn about how each of Earth’s spheres work together to create the Earth System.
2. Locate a NEWS ARTICLE published within the past 6 months available on the web that discusses a topic or event in which you can identify Earth’s spheres interacting. For example, an article on a recent hurricane would include interactions between the hydrosphere (hurricanes develop in the ocean), atmosphere (hurricanes are atmospheric storms), geosphere (erosion of the beaches), and biosphere (impacts to humans, animals and vegetation).
3. Do NOT summarize a reference or educational article explaining Earth’s spheres; this must be something happening in the NEWS.
4. There are many science news websites. Here are several to get you started however you may search on your own as well:
* Science News for Students
* Live Science – Best Science Websites
5. Write a minimum of 3 paragraphs: (paragraphs have 4-5 sentences)
* 1-2 paragraphs summarizing the article.
* 1-2 paragraphs that discussing the various spheres involved in the article. Include how the spheres are interacting, citing specific examples from the article.
* Include an appropriate citation (not just the link) for the news article.
* Include one image (photo, map, diagram) with a caption written by you that explains how the image relates to the discussion.
