Apes unit 4 progress check Question and answers correctly solved 2023/2024Students want to determine how vegetation affects soil erosion. They collect four soil samples of equal starting mass with different types of vegetative cover, as seen in the table below. Each sample is placed in a three-sided plastic dish that can drain into a beaker and is exposed to the same amount of consistent, steady rainfall for ten minutes. The water and soil runoff are collected in the beaker and separated. The average values for each sample are provided below. Which of the following is the control group for this experiment? - correct answer Soil with no grass Which of the following is a dependent variable in the experiment? - correct answer Percent change in mass of the soil sample A group of students wanted to determine if soil texture can vary by location. Several students brought in a sample of soil from their backyards. Each student added their soil sample of equal mass to a jar with exactly the same amount of water, shook the contents so that all soil particles were suspended in the water, and left the jars covered overnight. The next morning, the soil particles had settled out into layers and students could determine the percentage of each type of particle. The results of their soil test are shown below.
