Answer:
According to the search results, the answer to the question "Which of the following is not true about the spatial scales at which soil scientists study soils?" is A pedon must be significantly different in properties from... (Option A). This information is from Chapter 16 Flashcards | Quizlet [1]. A pedon is defined as a three-dimensional soil body with distinct physical, chemical, and biological characteristics that distinguish it from surrounding soils. Soil scientists study soils at several spatial scales, including the pedon scale (the smallest), the polypedon or soil profile scale, the catena or hillslope scale, the watershed or landscape scale, and the regional or global scale. Soil scientists study each of these scales to understand how different processes affect soil characteristics at different spatial scales. Option A is incorrect because pedons are not required to be significantly different in properties from surrounding soils; rather, they are defined by their distinct characteristics, regardless of whether they differ from surrounding soil.
