Our Home: Earth, a Unique Life Sustaining Planet
This chapter of the Class 8 NCERT Curiosity textbook asks why Earth alone teems with life. Learners examine a fortunate distance from the sun, a protective atmosphere rich in oxygen, and abundant liquid water cycling through rain, rivers and oceans. The magnetic shield, the ozone layer and steady temperatures are shown guarding living things from harsh radiation and extremes. Comparing barren neighbours sharpens gratitude for these conditions and responsibility toward keeping air, water and climate fit for life.
