Question

which is a renewable resource?
coal
iron
wood
petroleum

Explanation:

To determine a renewable resource, we analyze each option:

• Petroleum: A fossil fuel, non - renewable as it forms over millions of years and is finite.
• Wood: Comes from trees. Trees can be replanted and regrown within a human - relevant time frame, so it is renewable.
• Iron: A metal ore, non - renewable as it is mined from finite reserves in the Earth's crust.
• Coal: A fossil fuel, non - renewable as it takes millions of years to form and is a limited resource.

Answer:

The option with wood (the circle next to "wood") is the renewable resource. So the answer is the option labeled "wood".
