What is a natural resource?- A man-made tool used to measure weather
- Anything made in a factory from plastic
- A type of computer software
- A material or substance from the Earth that people use
Show the answerAnswer: D. A material or substance from the Earth that people use
Natural resources are materials that come from the Earth itself, such as water, soil, trees, minerals, and air, which humans use to meet their needs. 2. Which of these is an example of a renewable resource?- Sunlight
- Petroleum
- Coal
- Natural gas
Show the answerAnswer: A. Sunlight
Sunlight is renewable because it is naturally replenished on a human timescale and will not run out from use. 3. Why are fossil fuels classified as nonrenewable resources?- They form over millions of years, far slower than we use them
- They can be created instantly in a laboratory
- They never run out no matter how much is used
- They are not found underground
Show the answerAnswer: A. They form over millions of years, far slower than we use them
Fossil fuels such as coal, oil, and natural gas form from ancient organic material over millions of years, so once used they cannot be replaced within a human lifetime. 4. What does the term 'conservation' mean in Earth science?- The careful use and protection of natural resources
- Building new factories near forests
- Using up resources as fast as possible
- Removing all wildlife from a habitat
Show the answerAnswer: A. The careful use and protection of natural resources
Conservation means using resources wisely and protecting them so they remain available for the future and for ecosystems to stay healthy. 5. Which action is an example of water conservation?- Leaving the faucet running while brushing your teeth
- Taking very long showers daily
- Fixing a leaky pipe promptly
- Watering the lawn every day at noon
Show the answerAnswer: C. Fixing a leaky pipe promptly
Fixing leaks stops water from being wasted, which is a simple and effective way to conserve this important renewable resource. 6. What is recycling?- Mining new raw materials from the ground
- Throwing all waste into a landfill
- Burning materials to create pollution
- Processing used materials into new products
Show the answerAnswer: D. Processing used materials into new products
Recycling takes used materials like paper, glass, metal, or plastic and processes them so they can be made into new products, reducing the need for new raw materials. 7. Which of the following best describes soil as a resource?- It is classified the same as fossil fuels
- It is created instantly after a flood
- It cannot support plant life
- It is renewable but can take hundreds of years to form
Show the answerAnswer: D. It is renewable but can take hundreds of years to form
Soil is renewable, but forming just a few centimeters of fertile topsoil can take hundreds to thousands of years, so it must be protected from erosion and overuse. 8. What is deforestation?- The process of planting new trees
- The large-scale removal of trees from an area
- The natural regrowth of a forest after a fire
- A method used to conserve water
Show the answerAnswer: B. The large-scale removal of trees from an area
Deforestation is the large-scale clearing or removal of forests, often for farming, logging, or development, which can harm ecosystems and reduce biodiversity. 9. Which resource is considered inexhaustible because it cannot realistically be used up?- Copper ore
- Coal
- Natural gas
- Solar energy
Show the answerAnswer: D. Solar energy
Solar energy is considered inexhaustible because the Sun will keep producing energy for billions of years, far beyond any amount humans could use. 10. What is the main purpose of a wildlife conservation area or national park?- To build shopping centers
- To protect habitats and species from harm
- To allow unlimited hunting and logging
- To increase pollution in the region
Show the answerAnswer: B. To protect habitats and species from harm
Protected areas like national parks are set aside to preserve natural habitats, protect wildlife, and maintain healthy ecosystems for the future. 11. Which of the following is an example of reducing resource use?- Buying new clothes every week to keep up with styles
- Leaving lights on in empty rooms so they last longer
- Throwing away paper after using just one side of it
- Buying a reusable water bottle instead of many plastic ones
Show the answerAnswer: D. Buying a reusable water bottle instead of many plastic ones
Using a reusable water bottle reduces the number of single-use plastic bottles produced and thrown away, cutting down on resource use and waste. 12. Why is it important to conserve natural resources?- Because conservation makes resources disappear faster
- So that resources remain available for future generations and ecosystems stay healthy
- Because resources are unlimited and conservation is unnecessary
- So factories can produce more pollution
Show the answerAnswer: B. So that resources remain available for future generations and ecosystems stay healthy
Conserving resources helps ensure there is enough for people and ecosystems in the future, especially since many resources are limited or slow to renew. More free middle school sample lessonsSee all free sample lessons »
