Chapter 10, Earth — Our Shared Home, looks at the natural resources that support all life on Earth, and why protecting the environment is everyone’s responsibility. These questions revisit those ideas.
Practice Questions
Q1. Name two natural resources the Earth provides that living things depend on.
Air and water are two natural resources that all living things depend on; soil and sunlight are others.
Q2. What is an ecosystem?
A community of living things — plants and animals — interacting with each other and their non-living surroundings, like air, water and soil, in a shared environment.
Q3. Give one example of how humans can harm the environment.
Cutting down forests (deforestation), or polluting rivers with waste, both harm the environment.
Q4. Why is the Earth described as a “shared home” for all living things?
Humans, animals and plants all depend on the same limited air, water and land to survive, so the wellbeing of one affects all the others.
Q5. Name one action a student can take to help protect the environment.
Planting a tree, or reducing plastic use and reusing items instead of throwing them away.
Why These Help
Understanding the Earth as a shared, connected system helps students see how everyday choices — about waste, water and trees — ripple outward to affect the whole environment, not just their own surroundings.
Frequently Asked Questions
Q. Why should protecting the environment matter to every person, not just scientists?
Everyone shares and depends on the same Earth’s air, water and resources, so the choices each person makes — from saving water to reducing waste — directly affect the health of this shared home for years to come.
