β Minerals: Naturally occurring inorganic substances found in the Earthβs crust.
β Energy resources: Sources of energy obtained from natural resources, including minerals and fuels.
β Both are non-renewable resources and essential for economic development.
Detailed Explanation
This chunk introduces two important types of natural resources: minerals and energy resources. Minerals are defined as naturally occurring inorganic substances that are found in the Earth's crust. This means that they are solid, inorganic (not made of plant or animal matter), and have a specific chemical composition. Energy resources, on the other hand, refer to the various sources from which we derive energy, such as fuels and other natural materials. Both minerals and energy resources are categorized as non-renewable resources, implying that they cannot be replenished quickly once they are consumed. Their availability is finite, and they play a critical role in the economic development of countries, as they are crucial for industries, energy production, and overall infrastructure.
Examples & Analogies
Think of minerals and energy resources like the savings in a bank account. Just as you can only spend the money you have and it takes time to earn more, minerals and energy resources are limited. We use them up through various processes, and once gone, they cannot be easily replaced. This adds importance to how we manage and conserve these resources.
