Cheng made a chart to categorize resources.
Renewable and Nonrenewable Resources
| Resource | Renewable or Nonrenewable |
| :---------- | :------------------------ |
| Gold | Nonrenewable |
| X | Renewable |
| Cotton | Renewable |
| Fossil fuel | Y |
Which correctly completes the chart?
A. X : Geothermal energy
Y: Nonrenewable
B. X : Wind
Y: Renewable
C. X: Natural gas
Y: Nonrenewable
D. X : Plant fiber
Y: Renewable
Answer (2)
The problem requires identifying a renewable resource and correctly classifying fossil fuels. Geothermal energy is renewable, and fossil fuels are nonrenewable. Therefore, the correct answer is X : Geothermal energy and Y: Nonrenewable.
Explanation
Analyze the problem We need to determine which of the given options correctly fills in the chart. This means we need to identify a renewable resource for 'X' and correctly classify 'Fossil fuel' as either renewable or nonrenewable for 'Y'.
Evaluate each option Let's examine each option:
Option 1: X : Geothermal energy, Y: Nonrenewable
Geothermal energy is a renewable resource.
Fossil fuels are nonrenewable resources. This option is correct.
Option 2: X : Wind, Y: Renewable
Wind is a renewable resource.
Fossil fuels are nonrenewable resources. This option is incorrect.
Option 3: X: Natural gas, Y: Nonrenewable
Natural gas is a nonrenewable resource. This option is incorrect.
Option 4: X : Plant fiber, Y: Renewable
Plant fiber is a renewable resource.
Fossil fuels are nonrenewable resources. This option is incorrect.
Select the correct option Based on the analysis, only the first option correctly identifies a renewable resource for X (Geothermal energy) and correctly classifies fossil fuels as nonrenewable for Y.
State the final answer Therefore, the correct answer is: X : Geothermal energy Y: Nonrenewable
Examples
Understanding the difference between renewable and nonrenewable resources is crucial in environmental science and sustainability. For example, when planning a city's energy infrastructure, knowing whether to invest in solar power (renewable) or coal power (nonrenewable) has long-term environmental and economic implications. Renewable resources like solar, wind, and geothermal energy can be replenished naturally, making them sustainable options. Nonrenewable resources, such as fossil fuels (coal, oil, natural gas) and minerals, are finite and cannot be replenished at the rate they are consumed.
The chart needs a renewable resource for 'X' and confirms that fossil fuels are nonrenewable for 'Y'. Options that name renewable resources like geothermal energy or wind are suitable for X, while Y must confirm fossil fuels are nonrenewable. The options, while partially correct, do not both fulfill the requirements accurately.
