PW Class 6 Science Chapter 11: Nature’s Treasures Important Questions

Air, water, soil, forests, and fuels support life in different ways, but many of these resources are limited or take a very long time to form. Nature’s Treasures helps students understand where these resources come from, how they are used, and why they need to be conserved.

PW Class 6 Science Chapter 11 Important Questions bring these concepts into question-based practice. The selected questions below cover conservation, rainwater harvesting, forests, air, the water cycle, soil, and fossil fuels through a mix of objective, reasoning, and descriptive questions.
