To model a situation with a positive change in elevation, we need to find a change where the final elevation is higher than the initial elevation. Let's analyze each option:
1. **A change in elevation from 632 feet to 312 feet**: This is a decrease, as 312 is less than 632. (Negative change)
2. **A change in elevation from sea level to -87 feet**: Here, sea level is 0 feet, and moving to -87 feet is also a decrease. (Negative change)
3. **A change in elevation from –12 feet to 123 feet**: This involves moving from below sea level (−12 feet) to above sea level (123 feet). The change is positive because 123 is greater than -12.
4. **A change in elevation from 492 feet to -783 feet**: This is a significant decrease, as -783 is much lower than 492. (Negative change)
The only situation with a positive change is:
**A change in elevation from –12 feet to 123 feet.**
1. **A change in elevation from 632 feet to 312 feet**: This is a decrease, as 312 is less than 632. (Negative change)
2. **A change in elevation from sea level to -87 feet**: Here, sea level is 0 feet, and moving to -87 feet is also a decrease. (Negative change)
3. **A change in elevation from –12 feet to 123 feet**: This involves moving from below sea level (−12 feet) to above sea level (123 feet). The change is positive because 123 is greater than -12.
4. **A change in elevation from 492 feet to -783 feet**: This is a significant decrease, as -783 is much lower than 492. (Negative change)
The only situation with a positive change is:
**A change in elevation from –12 feet to 123 feet.**
