Answer: The change in elevation is 5,100 m.
Explanation:
Since we have given that
Initial height = 8,500 m
New height = 3,400 m
We need to find the change in elevation:
As we know the change in elevation is the difference between the heights:
So, it becomes,
![8500-3400\\\\=5,100\ m](https://img.qammunity.org/2019/formulas/mathematics/college/4uudvf3hm6yd04hlhx9wf861yw58zgdjkh.png)
Hence, the change in elevation is 5,100 m.
