Natural Resources and Their Use - Class 8 SST Free MCQ Test with solutions

Industrialization powered by fossil fuels often leads to the disturbance of natural cycles, including climate change and habitat destruction. These disturbances can have far-reaching effects on ecosystems and biodiversity, resulting in environmental degradation and loss of natural resources.

The International Solar Alliance aims to facilitate cooperation among countries with abundant sunshine to promote the use of solar energy. By encouraging collaboration on solar projects, ISA seeks to reduce dependence on fossil fuels and enhance access to clean, renewable energy for sustainable development.

The Natural Resource Curse, or Paradox of Plenty, refers to the phenomenon where countries rich in natural resources, like oil or minerals, often experience slower economic growth because they rely heavily on exporting raw materials instead of developing industries that add value. This can lead to economic instability and hinder long-term development.

Shifting to renewable energy sources is a crucial strategy to avoid the depletion of non-renewable resources. By transitioning to sustainable alternatives, countries can reduce their reliance on finite resources like coal and oil, ensuring a more sustainable future while minimizing environmental impact.

Natural resources are defined as materials or substances that originate from nature and hold value for human use. They include both living (plants, animals) and non-living (water, minerals) components of our environment. Understanding natural resources is essential for sustainable living and environmental stewardship.

Solar energy is a renewable resource because it can be replenished naturally and does not deplete over time when harnessed. Unlike fossil fuels such as coal and oil, which take millions of years to form and are consumed faster than they can be replaced, solar energy is abundant and continually available as long as the sun shines.

Overexploitation of groundwater leads to decreased water tables, meaning the underground water level drops due to excessive extraction beyond natural replenishment rates. This can cause long-term sustainability issues for agriculture and water availability, highlighting the need for responsible water management practices.

Renewable resources can naturally regenerate and are available indefinitely if used responsibly. They do NOT require long geological timescales to form—that is a characteristic of non-renewable resources. Also, renewable resources can be depleted if overused faster than they regenerate.

Traditional agricultural practices, such as those outlined in Vriksayurveda, focus on maintaining and enhancing soil health and fertility through natural methods. This approach emphasizes sustainable farming techniques that promote biodiversity and ecosystem health, contrasting sharply with chemical-intensive modern practices that can harm the environment.

A resource does not need to be abundant; even scarce resources can be economically feasible if they can be used profitably and affordably.
