To measure the effects of climate on soil formation, the following variables must be taken:
Independent variable: Soil sample
Dependent variable: Soil characteristics according to exposure to a climatic element such as rainfall.
To find out the effects of climate on soil formation, a soil sample is taken, which will be the independent variant. Subsequently, different samples of that sample are subjected to different climatic conditions. For example various levels of rainfall.
Subsequently, the results obtained in each soil sample are observed. According to this, the state of the soil is the dependent variable because, depending on the level of rainfall, the characteristics of the soil change, making it more or less fertile.
