What are the major differences between topographic and geologic maps?

• Refer to Figure 9.21 on p. 264 of the text. How would you determine the slope of the land surface in this figure? If you consider building a house in a location in this area, what is the best location for your house? Why?
• Refer to Figure 9.22 on p. 265 and locate at least three main structural features. Discuss why the Canmore community is established on the northeast side of the map.

The major differences between topographic and geologic maps are as follows:

1. Topographic maps: These maps provide information about the surface features of the Earth's land and include details such as elevation, contour lines, rivers, roads, and vegetation. They are primarily used to understand the shape and form of the land.

2. Geologic maps: These maps display the distribution of different rock types, geological formations, and other subsurface features. They provide information about the geology of an area, including the age, composition, and structure of rocks. Geologic maps are useful in understanding the geological history of an area and locating valuable mineral resources.

Now moving on to determining the slope of the land surface in Figure 9.21 on page 264 of the text:

To determine the slope of the land surface in the figure, you can use the contour lines. Contour lines connect points of equal elevation on a map. The closer the contour lines are to each other, the steeper the slope. On the map, you can identify two nearby contour lines and count the number of contour lines crossed between them. Divide the vertical distance between the contour lines by the horizontal distance traveled and multiply the result by 100 to get the slope percentage.

Regarding the best location for building a house in this area, a few factors need to be considered:

1. Slope: Generally, a gentle slope is preferable for building a house as it allows for better drainage and reduces the risk of erosion. However, a slope that is too steep can be unstable and may require additional engineering measures.

2. Accessibility: Choosing a location that is easily accessible to roads, utilities, and basic amenities is important for convenience and practicality.

3. Views and Exposure: Consider the view from the house and the exposure to sunlight. Depending on personal preferences, a location that offers a scenic view or receives ample sunlight may be desirable.

4. Potential hazards: Assess the risks associated with natural hazards like landslides, flooding, or earthquakes in the area. Avoiding high-risk areas is crucial for the safety of the house and its inhabitants.

Now referring to Figure 9.22 on page 265, there are several structural features to locate and discuss in the Canmore community on the northeast side of the map. Unfortunately, as an AI text-based model, I am unable to view or reference specific figures or maps. However, based on general knowledge, you may find features such as fault lines, folds, or intrusions in the geological map. The Canmore community may be established on the northeast side due to factors like accessibility, available resources, geological stability, or historical reasons. Without specific details from the map, it is challenging to provide a more precise explanation.
