As a geologist, you work for NASA, studying rock formations on other planets to figure out what the climate was like on that planet earlier in time. You are asked to analyze the rocks in the image below that were photographed on Mars. What can you determine about how these rocks formed? Explain.

a warm, wet climate will produce the highest rate of weathering. the warmer a climate is, the more types of vegetation it will have and the greater the rate of biological weathering (figure below). this happens because plants and bacteria grow and multiply faster in warmer temperatures.

the answer is d (apex) good luck : ))

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."
