Question

which of the following is a limited resource, which can take longer to be replenished than it takes to be used up?
a. drinking water
b. natural gas
c. copper metal
d. sun rays

Explanation:

• Drinking water is a renewable resource as it can be replenished through the water cycle relatively quickly.
• Sun rays are a renewable resource as the sun is expected to provide energy for billions of years.
• Copper metal is a non - renewable resource, but natural gas is also non - renewable. However, the key is that natural gas is a fossil fuel formed over millions of years. While copper is mined from ores, natural gas (a hydrocarbon fuel) has a much longer replenishment time compared to its usage rate in the context of human consumption.

Answer:

B. Natural gas
