One natural resource that we talked about in class that is slowly running out is
- A.
Trees
- B.
Water
- C.
Air
- D.
Fossil fuels
Correct Answer
D. Fossil fuelsExplanation
Fossil fuels are considered a slowly depleting natural resource because they are formed over millions of years from the remains of plants and animals. As human consumption of these fuels continues to increase, the rate at which they are being used exceeds the rate at which they are being formed. This leads to a gradual depletion of fossil fuel reserves over time. Additionally, the burning of fossil fuels releases carbon dioxide and other greenhouse gases, contributing to climate change and environmental degradation. Therefore, the correct answer is fossil fuels.Rate this question:
-
- 6.
Fossil fuels are actually
- A.
Dead plants and animals
- B.
Melted rocks
- C.
Liquid sand
- D.
Watered down soil
Correct Answer
A. Dead plants and animalsExplanation
Fossil fuels are formed from the remains of dead plants and animals that have been buried and subjected to heat and pressure over millions of years. This process transforms the organic matter into coal, oil, and natural gas. These fuels are considered non-renewable resources because they take a very long time to form and are being consumed at a much faster rate than they can be replenished.Rate this question:
