Which resource can be used up, but is considered renewable because it can be replaced itself?
A. Trees
B. Copper
C. Wind
D. Geothermal
C. Wind
The resource that can be used up but is considered renewable because it can replace itself is A. Trees.
The resource that can be used up but is considered renewable because it can be replaced itself is option A: Trees. Here's an explanation of how the answer is determined:
To identify which resource can be used up but is also considered renewable, we need to understand the concept of renewable resources. Renewable resources are those that are naturally replenished or can be replaced within a relatively short period, typically the same rate or faster than they are consumed or used.
Option A: Trees - Trees can be cut down and used for various purposes, such as timber for construction or paper production. However, new trees can be planted to replace those that are harvested, allowing for a continuous supply of wood.
Option B: Copper - Copper is considered a non-renewable resource because it is extracted from the Earth's crust, and once it is used up, it cannot be naturally replaced within a human-relevant timescale.
Option C: Wind - Wind is a natural phenomenon generated by the sun's uneven heating of the Earth's surface, and it is considered a renewable resource. However, it is not "used up" in the same sense as trees or other natural resources. Instead, it is harnessed to generate electricity using wind turbines, but the wind itself is continuously present and does not deplete.
Option D: Geothermal - Geothermal energy comes from the Earth's heat and is considered a renewable resource. However, it is not "used up" like trees; rather, it involves extracting the heat from underground sources and converting it into usable energy. The heat can be replenished over time through natural geological processes, making it renewable.
Therefore, the correct answer is option A: Trees, as they can be used up but are considered renewable since they can be replaced by planting new trees.
