Which conditions would be best for growing crops and creating fertile soil? -a. a lot of rainfall and high temperaturesb. moderate rainfall and no extreme temperaturesc. little rainfall and high temperaturesd. a lot of rainfall and low temperatures

b. moderate rainfall and no extreme temperatures

Explanation:

Both rainfall and temperature plays an important role in the fertility of the soil. The excess rainfall can cause leaching, soil erosion which will lower the mineral content of the soil. The low rainfall will limit the moisture content of the soil. The high temperature will cause dehydration or limitation of the soil moisture necessary for plant growth. Also the low temperature will cause the frosting of soil water this will effect the soil fertility.

On the basis of above description moderate rainfall and moderate temperature will be suitable as it will help in retaining the soil moisture and minerals.    

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