Texture and consistency of the soil have a direct relationship. Texture is the ratio of sand, silt, and clay in the soil; whereas, consistency is the degree to which soil resists pressure.The texture determines the consistency of the soil. For example, Soil that is high in sand is usually loose when dry or moist, and both nonsticky and nonplastic when wet. More loamy soil will be more likely to be softer, friable, nonsticky, and nonplastic. But, as clay content inreases, soil becomes harder, firmer, stickier, and more plasticHow might the consistence of soil affect the growth of plants? Think about both wet and dry conditions.The consistency of the soil can affect the plants based on the conditions the environment goes through such as wind and water. A windy area with a firm soil consistency would not require plants to have roots that are long and sturdy; however, a windy area with a loose soil consistency would require plants to have long and study roots to survive in the wind. The ability of water to go through the soil definitely aids in the growth of plants. For example, soil that is hard when dry is resistant to root penetration. Also, soil that is sticky and plastic does not drain well and tends to cut off air penetration when wet.Activity 3:Which of the three habitats did the organic nutrients (blue water) pass through most rapidly?The desert habitat leached the nutrients most quicklyWhat is the correlation between the speed in which nutrients pass through the soil layers and the amount of rainfall each habitat receives?Despite the fact that desert soil allows water to drain faster, it receives less rainfall than most other habitats. Temperate rainforests receive more rainfall, but the soil is composed of more organic material, which replenishes lost nutrients. Because of the high rainfall and level of weathering, soil in temperate rainforests tends to be more clayish, which in turn reduces the permeability of the soil. Prairies, rainfall wise, fall in the middle of deserts and rainforests. Rainy summer storms expose prairies to a decent amount of nutrient leaching, but these nutrients are replaced by an abundance of decomposing organic material.Which habitat has the greatest potential for groundwater contamination, and why?The habitats that have the greatest potential for groundwater contamination will have relatively low amounts of clay. With this in mind, the temperate rainforest cannot be the answer. The desert habitat leaches nutrients and chemicals the fastest, but usually there are not many nutrients found in the desert soil. Prairie habitats are made up of mainly farmland in which many pesticides have been added within the soil for fertilizer.Why do deserts have a larger C horizon than other habitats? Why are A and B horizons similar? How does this relate to the yearly rainfall that deserts receive?Deserts tend to have a larger C horizon than other habitats since they receive little rainfall. In addition, the parent bedrock of the desert undergoes little weathering. This is why there is more parent rock in the C horizon. The lack of rainfall implies that few minerals are leached from the upper horizons to the lower. With low nutrient content, desert soils also experience little biological weathering. Combined, these conditions result in a soil profile with similar A and B horizons.
