Final answer:
When creating a geological feature by clicking on the map, you are likely simulating the creation of a landform on a topographic map, and observing contour lines allows for understanding of terrain slope. Moreover, when adding contour lines, ensure that they are continuous and properly labeled to represent elevation changes accurately and create a three-dimensional perspective through cross-sections.
Step-by-step explanation:
In response to the geology-focused exercises described, when you select Add and click four times in the center of the landscape, you are most likely creating a geological feature on a digital topographic map or geologic simulation. By looking at the contour lines on the horizontal view after zooming in, you will likely notice that the spacing between lines indicates the slope of the terrain; closer lines suggest steeper gradients, while wider spacing implies a more gradual slope. This exercise is part of building an understanding of how to visualize and interpret landforms and their elevations on a map.
For the exercise involving the addition of contour lines to a topographic map with a contour interval of 100 meters, it is important to draw continuous lines that either stretch off the map or circle back on themselves to form an enclosed area. This simulates the process geologists use to translate real-world elevations into a map representation. Additionally, when creating cross-sections, the lines should be perpendicular to geological contact points and labeled consistently, such as with 'A-A'' or 'A-B' labels, to help visualize the three-dimensional arrangement of geological structures.
