(05.01 MC) According to the map, which of the following regions produced the most oil?

(06.04 MC) Acid deposition in a forest downwind from a coal-burning power plant has caused the soil’s pH to drop below 5.0. How is the forest affected by the pH decrease?

(05.03 LC) The table shows the amount of radioactive element remaining in a sample over a period of time: Radioactive Decay Rate Amount of Radioactive Sample (g) Time (min) 56.0 0 47.1 400 39.6 800 33.3 1,200 28 1,600 What is the half-life of the element in minutes?

(05.01, 05.06 HC) Energy intensity is considered a measure of the energy efficiency of a nation’s economy. It measures the quantity of energy needed to produce one unit (usually one dollar) of gross domestic product (GDP). Energy intensity can be used to compare countries or monitor a country’s energy efficiency over time. Most countries want to achieve economic growth with as low an energy intensity value as possible. © Our World in Data 2020   Use the map above to answer the questions: Identify one country that shows energy intensity lower than 2 kWh/$. Describe one variable that could be contributing to the low energy intensity of the country identified in (i). Compare the energy intensity of the country identified in (i) with a country with an energy intensity higher than 2 kWh/$. Describe one possible reason for the observed difference in energy intensity. There are methods for conserving energy on a large scale that can affect energy intensity of a country. The table below shows conversion factors for different types of renewable and non-renewable energy. Use the table to answer the questions:   Conversion Factors 1 kWh (kilowatt-hour) 3,412 Btu 1 gallon of gasoline 114,000 Btu 1 gallon of biofuel (B20) 127,500 Btu Improving the fuel economy of vehicles is one way of addressing energy intensity. Calculate the kilowatt-hour of energy available in 16 gallons of gasoline. Calculate the amount of biofuel that could be used to provide the same amount of energy. Provide reasoning for using biofuel as an energy source instead of regular gasoline. Describe two methods for conserving energy on a large-scale that could reduce the energy intensity of a household.

(08.05 MC) For the past 20 years, the population of the invasive Asian Carp in the Mississippi River has skyrocketed, while populations of native species have declined. Which of the following conclusions provides the best explanation for this phenomenon?

(05.01 MC) The graph below illustrates the historical and projected world marketed energy consumption from 1980–2030: How does the world marketed energy consumption change over the 25-year projection?

(05.04 MC) Which of the following would be the most likely impact on the environment of converting from biomass-produced methane to solar power as the primary energy source for a home?

(06.01 MC) A city council approves a new program to help reduce air pollution. The program involves filtering carbon monoxide from power plant exhaust. This policy will help directly reduce only which of the following categories of air pollutants?
