Question

Under which of the following types of resources can tidal energy be put?
A) Replenishable
B) Abiotic
C) Human-made
D) Non-recyclable
E) None of these

Answer 1

Hint: Everything present in our environment which can be used to fulfil our needs, provided, it is technologically accessible, economically feasible and culturally acceptable is referred to as ‘Resource’. Tidal energy, also called tidal power, is created using the movement of the ocean tides and currents.

Complete answer:
Tidal energy is renewable or replenishable energy powered by the natural rise and fall of ocean tides and currents. The long period waves that occur in the sea are known as tides, caused by the combined gravitational effects of the sun, the moon and earth’s rotation.

Now let us look into the given options:
A) Option A. Replenishable: It is the correct option. Replenishable resources are also known as recyclable resources and are those which can be quickly replenished, e.g. wind energy, hydel energy, tidal energy, etc.
B) Option B. Abiotic: Incorrect option. Abiotic resources are those resources that come from non-living sources, e.g. soil, rocks and minerals.
C) Option C. Human-made: Incorrect option. When a natural resource undergoes extreme change due to human intervention, it becomes a human-made resource. For example; steel is made by processing ire ore and hence steel is a man-made resource.
D) Option D. Non-recyclable: Incorrect option. Non-recyclable resources, also known as non-replenishable resources, are the ones that cannot be replenished in the near future, e.g. coal and petroleum.

Thus, the correct answer is Option A. Replenishable

Note: Renewable resources are being used to replace non-renewable sources on a wide scale these days because of their capacity to recover in a short period. They have the potential to regenerate and can be used over and over again. They are abundant and, as a result, have been used as the most common source of energy resources.
