Worksheet on renewable and nonrenewable resources for educational use.

Here’s the completed quiz with explanations for each answer.

I – Directions: Mark each item as RNR (Renewable Natural Resource) or NNR (Nonrenewable Natural Resource)

✔ Wind — RNR
*Explanation:* Wind is naturally replenished by atmospheric processes and is inexhaustible on a human timescale.

✔ Gold Jewelry — NNR
*Explanation:* Gold is a metal mined from the Earth. It takes millions of years to form and cannot be replaced once used up.

✔ Plastics — NNR
*Explanation:* Most plastics are made from petroleum (oil), which is a nonrenewable fossil fuel.

✔ Oil — NNR
*Explanation:* Oil is a fossil fuel formed over millions of years from ancient organic matter. Once extracted and burned, it cannot be replenished quickly.

✔ Copper — NNR
*Explanation:* Copper is a mineral mined from the Earth. While recyclable, its natural reserves are finite.

✔ Iron — NNR
*Explanation:* Iron ore is mined and processed into steel. Like copper, it’s a finite mineral resource.

✔ Lumber — RNR
*Explanation:* Lumber comes from trees, which can be replanted and regrown within decades if managed sustainably.

✔ Bauxite (Aluminum) — NNR
*Explanation:* Bauxite is the primary ore used to produce aluminum. It’s a finite mineral resource mined from the Earth.

✔ Ice Cubes — RNR
*Explanation:* Ice cubes are made from water, which is renewable through the water cycle (evaporation → condensation → precipitation).

✔ Water — RNR
*Explanation:* Water is constantly recycled through the hydrologic cycle, making it renewable — though local shortages can occur.

✔ Paper — RNR
*Explanation:* Paper is made from wood pulp (from trees). If forests are sustainably managed, paper is derived from a renewable source.

✔ Natural Gas — NNR
*Explanation:* Like oil and coal, natural gas is a fossil fuel formed over millions of years and cannot be replenished quickly.

✔ Trees — RNR
*Explanation:* Trees grow back if harvested responsibly. They’re a classic example of a renewable biological resource.

✔ Sunlight — RNR
*Explanation:* Solar energy is continuously available and will last billions of years — essentially inexhaustible for human purposes.

✔ Coal — NNR
*Explanation:* Coal is a fossil fuel formed from ancient plant material. It takes millions of years to form and is being consumed much faster than it forms.

✔ Soda Cans — NNR
*Explanation:* Most soda cans are made from aluminum (from bauxite) or steel (from iron ore) — both nonrenewable minerals. Even though they can be recycled, the original material is nonrenewable.

II – FILL IN THE BLANKS

✔ 1. The Earth's natural resources are divided in two _renewable_ and _nonrenewable_.

✔ 2. Some renewable resources are _wind_, _water_, _sunlight_, _trees_, _biomass_.
*(Other acceptable answers: geothermal, tidal, hydropower, etc.)*

✔ 3. Some Non-renewable resources are _oil_, _coal_, _natural gas_, _copper_, _iron_.
*(Other acceptable answers: gold, uranium, bauxite, phosphorus, etc.)*

✔ 4. Three products from renewable resources are _paper_, _lumber_, _biofuels_ (or _wind energy_, _solar panels_, _cotton fabric_).
*(Any 3 items that come directly or indirectly from renewable sources — e.g., wooden furniture, bamboo toothbrushes, ethanol fuel from corn, etc.)*

ANSWER KEY

Part I:
- Wind — RNR
- Gold Jewelry — NNR
- Plastics — NNR
- Oil — NNR
- Copper — NNR
- Iron — NNR
- Lumber — RNR
- Bauxite (Aluminum) — NNR
- Ice Cubes — RNR
- Water — RNR
- Paper — RNR
- Natural Gas — NNR
- Trees — RNR
- Sunlight — RNR
- Coal — NNR
- Soda Cans — NNR

Part II:
1. renewable, nonrenewable
2. wind, water, sunlight, trees, biomass *(any 5 renewable examples)*
3. oil, coal, natural gas, copper, iron *(any 5 nonrenewable examples)*
4. paper, lumber, biofuels *(or other valid products from renewables)*

📌 Note for Teachers/Students:
While some materials like aluminum or plastic *can* be recycled, they are still classified as NNR because their *original source* (bauxite, petroleum) is nonrenewable. Renewable resources are those that regenerate naturally within a human lifetime or shorter timeframe.
