microorganismsacids given off by decomposition which speed up the weathering processfunginutrients released from animal cells4 points question 6how does topography impact how much water soil receives?
the steeper the slope, the more water is held by the soil.the flatter the slop, the less water is held by the soil.the steeper the slope, the less water is held by the soil.topography does not impact the amount of water that can be held by soil.3 points question 7what impact will a cold, dry climate have on soil?
it will likely form soil very rapidly.it will likely form soil slower due to slower weathering rates.it will likely form soil faster than warm, wet environments.it will likely form soil at the same rate as a cold, wet climate.3 points question 8which of the following would most likely have the best developed soil?
