Question

A valley in California has an elevation of feet below sea level. A valley in Arizona has an elevation lower than the one in California. Which of these could be the elevation of the valley in Arizona? 3 feet 0 feet -5 feet -9 feet

Answer 1

The valley in California has an elevation of feet "below sea level".
Below sea level means below 0 feet, so it'd have -5 feet

The one in Arizona would be lower than it, so the elevation will definitely be -9 feet
