Hypotheses 1) The higher the angle, the less water infiltration. Justification: The steeper the slope, the faster the rate of throughflow and surface runoff of water which may accelerate mass movement and increase the risk of soil erosion. A steep slope will result in runoff, which will impact the amount of time the water will be available for infiltration. In contrast, gentle slopes will have less of an impact on the infiltration process due to decreased runoff. 2) The less infiltration rate there is the more vegetation there will be. Justification: Plants need water to survive and as infiltration rate decreases so does the water in the soil. As water in the soil decreases, the soil will become more dry which means that plant roots...
