Propose an hypothesis to explain the data.Scientists suggest a scientific hypothesis,or possible explanation of what they observe in nature.The data collected by Bormann and Likens showed a decrease in the ability of a cleared forest to store water and retain soil nutrients such as nitrogen.They came up with the following hypothesis,or tentative explanation for their data:When a forest is cleared,it retains less water and loses large quantities of its soil nutrients when water from rain and melting snow flows across its exposed soil.

提出了一種假說來解釋數據。科學家猜測一個科學假說，可以解釋他們觀察的自然。鮑爾曼和萊肯斯所收集的數據顯示，清除森林會使蓄水和保持土壤養分(像氮等)的能力減少。他們提出了以下假設，或暫時解釋他們的數據：當森林被清除，它保留了較少的水，當失去了大量的土壤養分的水時，暴雨和融化的冰雪流動在其暴露的土壤。
