Answer 1

C. a difference in water temperature

Step-by-step explanation:

Thermoclines are caused by an effect called stratification in lakes. The warm layer of water which is heated by the sun sits on top of the cooler, denser water at the bottom of the lake and they are separated by a thermocline. Thermocline depth in lakes varies depending on the heat of the sun and the depth of the lake.
