Fill in the blanks.
1. Non-renewable resources can only be used once.
2. Minerals are examples of localised resources.
3. Balance bricks are used to generate solar energy.
4. Gas is an example of a sustainable resource.
Answer (2)
Non-renewable resources cannot be replaced and include fossil fuels. Minerals are localized resources found in specific areas, while the term 'balance bricks' is not applicable in solar energy. Lastly, natural gas is not sustainable, contrasting with renewable energy sources like solar and wind.

Let's review and address each statement one-by-one to determine the nature of the resources mentioned:
Non-renewable resources can only be used once.
Non-renewable resources are those that do not replenish quickly enough to be considered sustainable over the long term. Once used, they cannot be readily replaced. Examples include fossil fuels such as coal, oil, and natural gas. These resources took millions of years to form and are consumed faster than they can be naturally replenished.
Minerals are examples of localized resources.
Localized resources are those that are found in specific locations and not widely distributed. Minerals can be considered localized because they often occur in concentrated deposits in certain geographical areas. For example, gold might be abundant in one region but scarce in another.
Balance bricks are used to generate solar energy.
This statement seems incorrect as 'balance bricks' is not a term commonly associated with solar energy generation. Typically, solar energy is harnessed using solar panels, which are made of photovoltaic cells that convert sunlight into electricity.
Gas is an example of a sustainable resource.
Natural gas is generally considered a non-renewable resource as it is a fossil fuel that takes millions of years to form. However, biogas can be considered a more sustainable resource because it is produced from organic materials such as plant and animal waste, which can be constantly replenished.
