The approximate water temperature at a depth of 125 meters would be closest to: (1) 15°C (2) 8°C (3) 13°C (4) 3°C
photoshop1234 [79]

Answer:

(2) 8 ºC

Explanation:

The range of the temperatures from the uppermost layers of the ocean - around 100 to 150 m -, which in this case is 125 m, is not always constant as they fluctuate due to the atmospheric heating and cooling, and also due to seasonal variations.

However, if we base our answer on the table below, we would determinate that the approximate water temperature at a depth of 125 meters is 8 ºC (2). This is because, if we observe, the temperature at 100 m is 12 ºC, while at 150 m is 5 ºC. Therefore, the temperature at 125 m should be higher than 5 ºC and lower than 12 ºC, that is 8 ºC.
