They collect water from a lake that has recently been  \nexposed to acid rain. They divide the water into 10 different tanks and add different amounts of limestone to nine of the tanks. No limestone is added to oneof the tanks. The pH of the water in the tanks is measured before the limestone is added and once every hour for 24 hours.  \n(g) Identify the independent variable in this investigation.  \n(h) Identify the dependent variable in this investigation.  \n(i) Identify the control group in this investigation.  \n(j) Describe how the results of the experiment would likely change if it was conducted at a lower temperature.  \n(k) Describe one additional variable that has not been mentioned that could affect the results of the investigation.  \n(l) Describe a modification that could be made to the investigation that would affect the results.  \nAP Environmental Science 2020 Exam | Sample Questions 3  \nSample Question 2  \n(Adapted from: 2020 Practice Exam \\#2)  \nAllotted time: 15 minutes (plus 5 minutes to submit)  \nAs the human population grows, more individuals are moving into urban areas. Geographic features and climatological factors can make some locations more prone to the effects of air pollution. The diagram below illustrates a city of millions of people and its surrounding geography. Human activities in urban areas can release pollutants into the air that lead to ground-level ozone and smog formation.  \n(a) Describe how a thermal inversion would form in the city shown in the diagram.  \n(b) Describe the relationship between a thermal inversion and pollution.  \n(c) Explain how one factor related to climate could make the city shown in the diagram susceptible to prolonged periods of ground-level ozone and smog.  \n(d) Explain how a geographical feature could make the city shown in the diagram susceptible to prolonged periods of ground-level ozone and smog.  \n(e) Explain how the average annual precipitation compares on the east and west sides ofthe mountains shown in the diagram.  \nAP Environmental Science 2020 Exam | Sample Questions 4  \nAir pollution is not the only problem associated with urbanization. Human-made structures in urban areas can increase the amount of runoff reaching streams and lakes.  \n(f) Describe how a common human-made structure found in urban areas contributes to urban runoff reaching streams and lakes.  \n(g) Propose a solution to reduce the effects of urban runoff from the structure you described in part (g) .  \n(h) Justify the solution proposed in (h) by describing an additional benefit of your solution, other than reducing the effects of urban runoff.  \nAP Environmental Science 2020 Exam | Sample Questions 5","cbCain3aEG7YWR04","https://ap.wps.com/l/cbCain3aEG7YWR04","pdf",694038,"English","# Sample Question 1\n## Carbon cycle processes and acid rain\n# Sample Question 2\n## Limestone remediation experiment variables\n# Sample Question 3\n## Thermal inversion, ozone and smog, precipitation\n# Sample Question 4\n## Urban runoff causes and mitigation","[{\"question\":\"What topics does Sample Question 1 test?\",\"answer\":\"It tests processes in the carbon cycle, fossil-fuel impacts over time, acid rain causes from an energy source, and methods to reduce acid rain.\"},{\"question\":\"How is the limestone investigation structured in Sample Question 2?\",\"answer\":\"Water exposed to acid rain is divided into 10 tanks; different limestone amounts are added to nine tanks, none to one tank, and pH is measured repeatedly over 24 hours.\"},{\"question\":\"What factors make the city vulnerable to ground-level ozone and smog in Sample Question 3?\",\"answer\":\"Thermal inversion formation and relationships to pollution are addressed, along with climate-related factors and geographical features that can prolong ozone and smog.
