Which of the following is an example of a renewable resource?
Correct Answer
B. Cotton
Explanation
Cotton is an example of a renewable resource because it is derived from plants that can be grown and harvested repeatedly. Unlike copper, natural gas, and coal, which are non-renewable resources that are finite in supply and take millions of years to form, cotton can be replanted and grown again after it has been harvested. This makes cotton a sustainable option for various industries such as textiles and clothing production.

In a nuclear power plant, what is used to change water into steam?
Correct Answer
D. Heat released from nuclear fission reactions
Explanation
In a nuclear power plant, water is changed into steam through the heat released from nuclear fission reactions. Nuclear fission involves the splitting of atomic nuclei, which releases a large amount of energy in the form of heat. This heat is then used to generate steam, which in turn drives turbines to produce electricity. Unlike the other options mentioned, such as burning natural gas, geothermal energy, or captured solar energy, the heat released from nuclear fission reactions is specifically used in nuclear power plants to convert water into steam.
15.
Most of the pollution in the atmosphere (air) comes from
Correct Answer
D. Burning fossil fuels
Explanation
Burning fossil fuels is the correct answer because it is a major source of pollution in the atmosphere. When fossil fuels such as coal, oil, and natural gas are burned for energy, they release harmful pollutants such as carbon dioxide, sulfur dioxide, and nitrogen oxides. These pollutants contribute to air pollution and can have negative effects on human health and the environment. While pollen, forest fires, and volcanic eruptions can also contribute to air pollution, they are not as significant or widespread as the pollution caused by burning fossil fuels.
16.
Which of the following statements are true? Check all that apply.
Correct Answer(s)
A. Oil lies under a shale seal
C. It is expensive to drill for oil...
Explanation
The statement "oil lies under a shale seal" is true because shale is a type of rock that can act as a seal, preventing the oil from migrating upwards. This is why oil is often found trapped beneath layers of shale.
The statement "it is expensive to drill for oil" is also true. Drilling for oil requires advanced technology, equipment, and expertise, which can be very costly. Additionally, oil exploration and extraction often involve complex processes such as seismic surveys and drilling deep into the earth, further adding to the expenses involved in the oil drilling industry.

Coal, oil, natural gas, and propane are fossil fuels. They are called fossil fuels because:
Correct Answer
C. They were formed from the buried remains of plants and tiny animals that lived hundred of millions of years ago
Explanation
Coal, oil, natural gas, and propane are considered fossil fuels because they were formed from the buried remains of plants and tiny animals that lived hundreds of millions of years ago. Over time, the organic matter was subjected to high pressure and heat, resulting in the formation of these fuels. This process took place over an extended period, making them nonrenewable resources. Burning fossil fuels releases energy, but it also contributes to air pollution. Therefore, the correct answer is that fossil fuels were formed from the buried remains of ancient plants and animals.
25.

Ireland accounts for 0.007% of the global population yet produces ___ of all CO2 emission released into the atmosphere (global emissions).
Correct Answer
E. 0.15%
Explanation
Ireland accounts for a very small portion of the global population, only 0.007%. However, it produces a significant amount of CO2 emissions, specifically 0.15% of all global emissions. This suggests that Ireland's CO2 emissions are disproportionately high compared to its population size.
28.
Which sector produces the most CO2?
Correct Answer
C. Electricity and Heat
Production
Explanation
Electricity and Heat Production is the sector that produces the most CO2. This is because the generation of electricity and heat often relies on the burning of fossil fuels such as coal, oil, and natural gas, which release large amounts of CO2 into the atmosphere. The transportation sector also contributes significantly to CO2 emissions, but it is surpassed by the emissions from electricity and heat production. Manufacturing and construction, as well as residences, also contribute to CO2 emissions, but to a lesser extent compared to the other sectors mentioned.
