Los Angeles Southwest College Geography Maps Questions

Part 1

Use the following map to answer the questions below.

• The elevators and distances are all in feet.
• North is at the top of the image
• Streams are shown with dashed lines
• A graphic scale is provided
• Use interpolation to determine elevations which are not exactly on a counter line.

1. What is the contour interval?

Hint: The contour interval is the difference between successive two contour lines. The contour interval can be found by using the index contours (thicker contour lines) which have marked elevations then dividing by 5(the number of contour lines between index contours.

2. What is the elevation difference between index contours?

Index contours are the thicker lines that are also marked with an elevation number.

3. What is the elevation of point A?

4. What is the elevation of point H?

5. What is the elevation of point B?

6. What is the elevation of point R?

7. Which lettered point has the highest elevation and what is that elevation?

8. Which lettered point has the lowest elevation and what is the elevation?

9. What is the local relief of this map (the difference between the highest location and the lowest location? That location does not have to be lettered, though it may be,)

10. Is it possible to see point D from point F?

11. Is it possible to see point D from pint B?

12. What is the horizontal distance from point C to B?

Group of answer choices

5500 feet

13. What is the horizontal distance from point I to R?

14. What is the elevation difference between points N and M?

15. What is the elevation difference between points C and E?

16. In which direction does Rush Creek Flow?

From the _________ to __________

17. Where is the location of the steepest slope on the map?

Part 2

Lab 11: Formulate geographic research questions and hypothesis

Overview

You will collaborate with your peers using this Canvas discussion board to formulate geographic research questions and hypotheses about geography patterns and processes.

• Post a reply to this discussion board a with a written paragraph (1 pts, 5 sentence minimum) reflection on a specific geography research question about the age of a place or item, and why you have the question. You must choose a natural physical geography feature or place, not a human-made or conceived place (e.g., no artificial lakes or the Bermuda Triangle!). Include an image of the feature or place, with a caption describing the image and a citation for the images source.
• Your reply should use the language: “I have always wondered about _____________ because ______? How do scientists know the age of _________________? What evidence do scientists have about the age of ________________?

• Read your peers research questions and then reply to at least two of their questions where you provide a specific evidence based hypothesis to answer the student question. (2 pts each, 10 sentence minimum).
• Your reply should include the following language: “I would like to address the research question ________________.” “The best way to determine the age of ____________ would be to _____________.” “Scientists know the age of _____________ because of the following research _______________.” “I used background information from _________ in my answer.”

Greetings Classmates,

If you haven’t traveled up to California’s Eastern Sierras, I strongly recommend it as there are several amazing sites to see. One of those are the tufa formations in Mono Lake. I have always wondered about tufa formations because of the sheer oddity of these formations rising from the ground. According to scientists, the lake and formations are over a million years old. How do scientists know the age of these formations and the lake itself? What evidence do scientists have about the age of the tufa formations at Mono Lake?

Hello Everyone:

For 15 years I was able to live in the Las Vegas desert. While living in Las Vegas discovering all it’s ancient history, I traveled to the Valley of Fire State Park. I have always wondered about the arch formation because they are all so perfectly formed into different shapes. In my research I learned the valley was formed 150 million years ago, how do scientists know the age of these formations_? What evidence do scientists have about how the shifting of the sand due to wind erosion was able to create such formation from sand. In review of picture two it appears of it there is a hand or arm going into the ground.

Part 3

1. What is the contour interval of this map?

2. What is the distance between index contours on this map?

3. What is the elevation of point A?

4. What is the elevation of point H?

5. What is the elevation of Tulik Vol?

6. How many miles is it from Point G to Point B?

7. How many miles is it from point H to point F?

8. What is the elevation at the top of the caldera of Okmok caldera?

Hint: there are several spot elevations marked around the rim. Identify one and choose that as your answer.

9. Okmok Caldera previously erupted. What evidence can you see from the topographic map and video lecture discussion that tells you there is still volcanic activity occurring?

For the next questions, use the full map provided which includes both Okmok Crater and Mount Vsevidof.

10. Which is taller, Okmok Caldera or Mount Vsevidof?

11. How many miles is it from Point D to point L?
