1. As the water depth increase the temperature of the water decreases.
2. (2)8 Celsius
3. The above answer was determined by throughout the chart the water depth increases by 25 but then a 100 it increases by 50. Each time that the water depth increased by 25 the water temperature decreased by 3. So if we follow that trend at the water depth of 125 the water temperature would be 9 Celsius. So the answer would be (2) 8 Celsius because that’s the closest number to 9 Celsius.
