Bathymetric maps represent underwater topography by using contour lines to illustrate water depth, similar to how topographic maps represent elevations of land. Contour lines on a bathymetric map represent specific depth intervals, with closer lines indicating a steeper underwater slope. The zero contour line on both topographic and bathymetric maps begins at sea level. While topographic maps measure elevations above sea level, bathymetric maps measure water depths below sea level to map underwater features like submarine canyons.

2. Topographic map.

3. What is the name of each continuous line that was drawn?

4. The name of each continuous line that was drawn is called a contour line.

5. How does the distance between two contour lines relate to the rise in elevation of the object? What is the term used for a change in elevation between two points?

6. As the elevation rises the lines go inword, as it rises. The relief is the term used for a change in elevation between two points.

7. What is the name given to the elevation raise between two contour lines?

8. The change in the reliefe between two adjacent contour lines is known as the contour interval.

9. If the distance between two contour lines is very close, what does that mean about the slope of the hill or mountain?

10. It means that the hill’s or mountain’s slope is not that steep.

11. If the distance between two contour lines is far away, what does that mean about the slope of a hill or mountain?

12. It means that the hill’s or mountain’s slope is steep.

13. Look at the topographic map you have made and determine the height, in centimeters, of the object. Remember, the first contour line you drew was at zero centimeters. How high was your object according to the map? What is the change in relief?

14. Well my biggest object is according to the map about 10 centimeters and he relief keeps going up.

15. Measure the height of the object with a ruler how high is the object with the ruler? Are these heights the same?

16. The object actually was 14 centimeters. The heights are not the same.

17. Do you think that a topographic map will always show the correct height of a mountain or hill? Explain why or why not?

18. I think a topographic map could show a good guess as to the correct height of a mountain of hill. I think this because my map was pretty close to the right height, but it wasn’t the correct height. I know scienitis who draw topographic maps are way better at drawing them at me, so their’s are probably closer to the correct height of a mountain or hill.

19. Inmagine that the object you just mapped was underwater, like it was when you finished mapping it. Do you think topographic map techniques could be made of an underwater mountain of canyon? Why or why not?

20. No, because I had to add a centimemter of water slowly to create my map, if the mountain is underwater you can’t draw the mountain as the water rises in elevation.

21. A topographic map of the bottom of a body of water is called a bathymetric map. If the object you just mapped was underwater, and the top of the object was at zero feet below water, what could each contour intercal reprsent in water depth?

22. It could reprsent how deep the water.

23. How deep in centimeters would the bottom of the object you mapped be if the top of the object was right at water leve?

24. 10 centimeters deep.

25. What point in the world do you think the zero contour line begins for topographic and bathymetic maps?

26. Probably at sea level.

27. Compare and contrast topographic elevation with bathymetric depth.

28. Both of these maps have to do with how elevation and depth of a landmass. Topographic maps have to do with hills, mountains and more landmasses. Where bathymetric maps seem to be used for measurements of the depths of oceans or lakes.
