Across
- 2. The ability to do work; renewable and nonrenewable energy sources affect environmental sustainability
- 4. Organic matter from living organisms, used as a renewable energy source
- 5. The layer of gases surrounding Earth that protects life and controls weather and climate
- 6. All living organisms in a specific area or ecosystem
- 7. The solid part of Earth (rocks, soil, landforms) that supports ecosystems and human activity
- 9. The release of substances (such as greenhouse gases) into the atmosphere
- 14. Large, slow-moving ice masses that store freshwater and indicate climate change when they melt
- 15. A vital gas for respiration and combustion, produced mainly by plants through photosynthesis
- 16. The long-term pattern of weather conditions in a region
- 18. The introduction of harmful substances into the environment that damage ecosystems and human health
- 20. Meeting present needs without harming future generations or the environment
- 25. An online data source that tracks real-time global statistics such as population, emissions, and resource use
- 26. The number of individuals living in an area; population growth increases demand for resources
- 27. Materials that can break down naturally by microorganisms, reducing pollution
- 29. All water on Earth (oceans, rivers, lakes, groundwater) that supports life and regulates climate
Down
- 1. Frozen parts of Earth (ice caps, glaciers, snow) that influence sea levels and global temperature
- 3. All living and nonliving surroundings that affect life on Earth, including air, water, land, and organisms
- 4. The variety of life on Earth; high biodiversity increases ecosystem stability
- 8. The protection and sustainable management of natural resources and ecosystems
- 10. Natural materials (water, minerals, forests) used by humans for survival and development
- 11. The study of population size, structure, and trends affecting environmental impact
- 12. Actions taken to reduce environmental damage, especially climate change effects
- 13. Land degradation in dry areas caused by climate change and human activities
- 17. All regions of Earth where life exists, including land, water, and air
- 19. The growth of cities, often increasing pollution and resource consumption
- 21. The study of interactions between organisms and their environment
- 22. Energy emitted as waves or particles, including solar radiation that affects climate
- 23. A chemical element essential for life; its movement through the carbon cycle affects climate change
- 24. A decrease in population that can reduce environmental pressure but affect economies
- 28. Tiny particles or droplets in the air that influence climate and air quality
