Question

Natural disasters are powerful events caused by nature that can change the environment suddenly and sometimes dangerously. Some common natural disasters include earthquakes, hurricanes, floods, wildfires, and tornadoes. These events can destroy homes, forests, and habitats for animals. For example, a hurricane’s strong winds and rain can flood cities and damage trees, while a wildfire can burn large areas of forest and force animals to move away.

Natural disasters affect the environment in many ways. They can pollute water, destroy plants, and change the land. After a disaster, it can take a long time for nature and people to recover. It is important to learn about natural disasters so we can be better prepared and help the environment recover afterward.

14. B. Cause and effect

Short answer questions

15. Example — Wildfire: Wildfires burn vegetation and trees, destroying animal habitats and food sources. They leave soil exposed, which increases erosion and runoff into rivers. Smoke and ash pollute the air and water. Over time the landscape may change as fire-adapted species move in or as replanting and recovery alter the ecosystem.

16. It’s important to learn about natural disasters so people can prepare (reduce loss of life and property), respond safely during events, and help ecosystems recover afterward. Knowledge helps communities plan, build resilient infrastructure, protect water and soil, and care for displaced wildlife.

17. Ways communities can prepare to protect the environment:
- Create and practice emergency plans and early-warning systems.
- Use land planning and building codes (e.g., elevate buildings in flood zones, fire-resistant materials).
- Reduce fuel for fires with controlled burns, cleared vegetation, and firebreaks.
- Restore and protect natural buffers like wetlands, dunes, and forests that reduce flood and storm impacts.
- Prepare debris- and hazardous-materials-response plans to prevent pollution after a disaster.
- Organize community education, drills, and volunteer recovery teams for rapid, coordinated response.
