Chapter 11 (Part 2, Chapter 2): Life on Earth
Chapter 11 (Part 2, Chapter 2 in the printed book). On this site the chapters of both parts are numbered continuously.
"Life on Earth" is a Geography chapter of about twenty-four pages that follows the one on oceans. Students are likely to study the biosphere, how living things are distributed across the world, biomes and ecosystems and the interdependence of life and its environment. It links with the Science chapters on diversity and on how nature works in harmony, and with the Grade 8 chapter on natural resources. Maps of biomes and a study of a local ecosystem make it practical.
This is chapter 11 (Part 2, Chapter 2) of 15 in Exploring Society: India and Beyond, the Class 9 Social Science textbook, in the Geography section, and begins on page 21 of Part 2 of the printed 2026-27 book. It follows "Oceans and Life" and is followed by "Resistance and Resilience (1000–1700 CE)".
The aim of "Life on Earth" is understanding, not recall. Students should be able to explain ideas in their own words, give local examples and ask their own questions. Teachers can encourage them to collect stories, objects and information from home and the neighbourhood, which makes the chapter personal and meaningful and builds respect for different views.
At home, talk with your child about "Life on Earth": ask what they found interesting and what they would like to find out. Look at a map or atlas together, share family stories and relate the chapter to your neighbourhood or community.
