Question

Which resource can be used up but is considered renewable because it can replace itself?

a) Natural gas
b) Petroleum
c) Coal
d) Timber

Answer 1

Timber is considered a renewable resource because trees can be replanted and regrown, unlike natural gas, petroleum, and coal, which are nonrenewable because they take millions of years to form and exist in fixed amounts. The correct answer is d.

Step-by-step explanation:

The resource that can be used up but is considered renewable because it can replace itself is d) Timber. Timber is sourced from trees, which can be replanted and regrown over time. This makes timber a renewable resource when managed sustainably. In contrast, nonrenewable resources such as a) Natural gas, b) Petroleum, and c) Coal exist in fixed amounts and take millions of years to form. Therefore, once used up, they cannot be replaced within a human timeframe, making them nonrenewable. The correct answer is d.
