Question

Why is it important to always know the vertical exaggeration of a topographic profile?

Answer 1

Knowing the vertical exaggeration of a topographic profile is important because it helps to accurately interpret the elevation changes represented in the profile.

Step-by-step explanation:

Knowing the vertical exaggeration of a topographic profile is important because it helps to accurately interpret the elevation changes represented in the profile. Vertical exaggeration refers to the difference in scale between the vertical and horizontal axes of the profile. In many cases, the horizontal scale on a topographic profile is longer than the vertical scale, resulting in vertical exaggeration.

By understanding the vertical exaggeration, we can determine the apparent angle of dip of geological features. A higher vertical exaggeration can make features appear steeper than they actually are, while a lower exaggeration may make them appear less steep. For example, a thrust fault with a true dip of 25° might appear to dip 60° with a vertical exaggeration of 3x.

Therefore, knowing the vertical exaggeration allows us to accurately interpret the topographic profile and understand the true nature of the elevation changes and geological features depicted.

Answer 2

There are instances of low, rounded and subdued topographic features that sometimes being overlooked in the field and has not been seen or observed that's is why vertical exaggeration is necessary to enhance the measurement of height in models and presentation of terrains.
