Answer
Explanation:
Step1: Compare negative values
We know that for negative numbers, the larger the absolute - value, the smaller the number. The absolute value of - 657 is 657, and the absolute value of - 333 is 333. Since 657>333, - 657 < - 333.
Step2: Compare all values
We have the elevations: - 657, 488, 1142, - 333, 0. Negative numbers are less than 0 and positive numbers. Among the negative numbers, - 657 is the smallest.
