Grade 7 CRE – USE AND MISUSE OF NATURAL RESOURCES Quiz

1. Which of the following is an example of sustainable use of natural resources?

Dumping toxic waste into rivers
Building factories in national parks
Cutting down all the trees in a forest for timber
Planting trees to replace those that have been cut down
Explanation:

Planting trees to replace those that have been cut down ensures that the forest ecosystem can regenerate and continue to provide resources in the future.

2. What is one consequence of over-exploitation of natural resources?

Increased biodiversity
Improved air quality
Healthy ecosystem
Soil erosion
Explanation:

Over-exploitation of natural resources can lead to soil erosion, which can have detrimental effects on agriculture and the environment.

3. Which of the following is a renewable resource?

Coal
Natural gas
Solar energy
Petroleum
Explanation:

Solar energy is a renewable resource because it is constantly replenished by the sun. Coal, natural gas, and petroleum are non-renewable resources.

4. What is the term used to describe the process of using natural resources in a way that ensures they will be available for future generations?

Extraction
Over-exploitation
Conservation
Pollution
Explanation:

Conservation is the practice of using natural resources in a sustainable way to ensure they are available for future generations. Over-exploitation, pollution, and extraction do not focus on long-term sustainability.

5. Which is an example of the misuse of natural resources?

Recycling paper and plastic waste
Dumping industrial waste into rivers
Planting trees in deforested areas
Using solar panels for energy
Explanation:

Dumping industrial waste into rivers can pollute water sources and harm aquatic ecosystems, leading to long-term negative impacts on the environment.

6. What can individuals do to help conserve natural resources?

Pollute the air and water
Ignore environmental issues
Use resources wastefully
Reduce, reuse, and recycle
Explanation:

By following the principles of reduce, reuse, and recycle, individuals can help minimize the demand for new resources and reduce waste generation.

7. Which of the following activities contributes to deforestation?

Clearing land for agriculture
Promoting wildlife conservation
Growing trees in urban areas
Implementing sustainable logging practices
Explanation:

Clearing land for agriculture involves cutting down trees to create space for farming, which can lead to deforestation and loss of biodiversity.

8. What is one negative impact of air pollution on natural resources?

Promoting plant growth
Enhanced soil fertility
Increased water quality
Acid rain damaging forests
Explanation:

Air pollution can lead to the formation of acid rain, which can damage forests, reduce soil fertility, and harm aquatic ecosystems.

9. Which of the following is a non-renewable resource?

Wind energy
Timber
Fish stocks
Fossil fuels
Explanation:

Fossil fuels, such as coal, oil, and natural gas, are non-renewable resources because they take millions of years to form and cannot be easily replenished.

10. Why is it important to protect natural resources?

To prevent future generations from using them
To encourage over-exploitation
To maintain ecosystem balance
To ensure their depletion
Explanation:

Protecting natural resources helps maintain ecosystem balance, supports biodiversity, and ensures the sustainability of essential resources for current and future generations.
