Chapter 14: Natural Resources – NCERT Exemplar Solutions for Class 9 Science
This chapter highlights the importance of natural resources like air, water, soil, and energy sources, which sustain life on Earth. Students learn how these resources interact within the biosphere and provide the essential conditions for survival. The atmosphere and its role in climate regulation, the hydrosphere and the water cycle, and soil formation through weathering of rocks are explained in detail.
The chapter also explores the concept of biogeochemical cycles such as the carbon cycle, oxygen cycle, nitrogen cycle, and water cycle. These cycles illustrate how matter is continuously recycled in nature. Human activities like deforestation, pollution, and over-exploitation of resources are discussed to show how they disturb the balance of natural systems. Students also study the role of living organisms in maintaining ecological balance and how conservation practices like afforestation, rainwater harvesting, and waste management help protect natural resources. Real-life examples are provided to make the concepts relatable.
