Natural Resources and Conservation Quiz

Grade 4 · Science · Quiz

Test what you know about Earth's resources and how we can protect them.

Questions

1. Which resource is renewable?

   1. Iron ore
   2. Natural gas
   3. Wind energy
   4. Petroleum (oil)
   Show answer

   Answer: Wind energy

   Wind is a renewable resource because it is constantly produced by nature and will never run out. Iron ore, natural gas, and oil are all nonrenewable.

2. Why are fossil fuels considered nonrenewable?

   1. They are too expensive to use
   2. They cause pollution when burned
   3. They take millions of years to form and cannot be replaced quickly
   4. They are found only underground
   Show answer

   Answer: They take millions of years to form and cannot be replaced quickly

   Fossil fuels like coal and oil formed over millions of years from ancient organisms. We use them far faster than they form, so they cannot be replaced.

3. Which of the following is the BEST example of conservation?

   1. Leaving the lights on all night
   2. Throwing glass bottles in the trash
   3. Taking a shorter shower to save water
   4. Driving everywhere instead of walking
   Show answer

   Answer: Taking a shorter shower to save water

   Taking shorter showers reduces water use, which is a direct example of conservation. The other options waste resources unnecessarily.

4. Cutting down large areas of forest is called:

   1. Conservation
   2. Deforestation
   3. Erosion
   4. Pollution
   Show answer

   Answer: Deforestation

   Deforestation is the large-scale removal of forests. It destroys animal habitats, reduces biodiversity, and can increase carbon dioxide levels in the atmosphere.

5. Which energy source is BOTH renewable and produces no pollution when used?

   1. Coal
   2. Natural gas
   3. Solar energy
   4. Oil
   Show answer

   Answer: Solar energy

   Solar panels convert sunlight directly into electricity without burning anything, producing no air pollution. Sunlight is also unlimited and free.

6. Soil is considered a natural resource because:

   1. It is made in factories
   2. Plants need it to grow and it supports life
   3. It can be burned for energy
   4. It is found only near rivers
   Show answer

   Answer: Plants need it to grow and it supports life

   Soil is a natural resource because it provides the nutrients, water, and anchorage that plants need to grow, supporting nearly all land-based food chains.

7. Recycling aluminum cans helps conserve natural resources by reducing the need to mine new aluminum.

   Show answer

   Answer: True

   Recycling aluminum requires about 95% less energy than making new aluminum from ore, and it reduces the need to mine bauxite, conserving land and resources.

8. Coal, oil, and natural gas are called ______ fuels because they formed from ancient living things.

   Show answer

   Answer: fossil

   These fuels are called fossil fuels because they formed from the fossilized (preserved) remains of plants and animals that lived millions of years ago.
