The independent variable is the one that causes an effect on the dependent variable. In this case, the independent variable is depth. Different depths lead to a variation in temperature. 2) depths.

<h3>What are de dependent and independent variables?</h3>

Independent variables are those modified or changed by the researcher to study how this change affects another variable and hence the results.

This variable is not affected by any other one but influences or causes a reaction in other variables.

The dependent variable is the one influenced by the independent variable, and is affected by any change on this last one.

Its response might be either directly proportional or inversely proportional to the change in the independent variable.

Now let us answer the question.

The aim of the study was probably to analyze how temperature changed with depth.

So, according to this, depth influenced on the temperatureof water.

The independent influencing variable is depth.
The dependent affected variable is water temperature.

The correct option is 2. depths.
