Natural Resources

Overview

Natural resources form a foundational topic in EVS for Varg-3 (Primary level) of MP TET. This topic connects children's everyday experiences—breathing air, drinking water, playing in soil—with larger concepts of resource conservation and sustainability. Questions typically test factual knowledge about types of resources, their sources, uses, and conservation methods.

For the exam, you must understand the classification of resources (renewable vs non-renewable), properties of air/water/soil, types of minerals and energy sources found in India and Madhya Pradesh, and basic conservation practices. MP-specific content like the state's mineral wealth (diamonds from Panna, coal from Singrauli) frequently appears in questions.

This topic integrates science and social studies, making it a high-scoring area if you master the key facts and their environmental implications.

Key Concepts

• **Natural resources** are materials or substances found in nature that humans use for survival and development—they are not made by humans.

• **Renewable resources** can be replenished naturally within a human lifetime (sunlight, wind, water, forests), while **non-renewable resources** take millions of years to form and are exhaustible (coal, petroleum, minerals).

• **Air** is a mixture of gases; nitrogen (78%) and oxygen (21%) are the main components. Oxygen supports life and burning; carbon dioxide is used by plants in photosynthesis.
