Earth and Space Science

8. Water that flows over the Earth's surface into rivers, lakes, and oceans instead of soaking into the ground.
9. (8, 10, 6) An increase in average surface temperature resulting from increased atmospheric greenhouse gas concentrations due to human activities.
12. The short-term conditions of the atmosphere at a particular place and time, including temperature, rainfall, wind, and humidity.
13. Carbon dioxide + water = glucose + oxygen.
17. The process by which water enters the soil from the Earth's surface.
18. The process by which plants, algae, and some bacteria convert light energy into energy.
19. All of Earth's water, including oceans, rivers, lakes, groundwater, ice, and water vapour.
20. The release of water vapour from plants through tiny openings in their leaves.
22. (7, 6) Long-term changes in Earth's climate patterns, including temperature, rainfall, and weather events, caused by both natural processes and human activities.
25. The process by which organisms exchange gases with their environment to produce energy.

1. Any form of water that falls from the atmosphere to Earth, such as rain, snow, sleet, or hail.
2. (8, 2, 7, 6) Glacial retreat, ice core analysis, pollen and fossil records and sea level change.
3. The layer of gases surrounding Earth that supports life and influences weather and climate.
4. (6, 7) The long-term increase in Earth's average surface temperature, mainly due to the enhanced greenhouse effect.
5. The process of burning carbon-based materials like fossil fuels and wood in the presence of oxygen.
6. (5, 10, 5) Carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O) and water vapour (H₂O).
7. (10, 6) A natural process where greenhouse gases in the atmosphere absorb and re-radiate heat, helping keep Earth warm enough to support life.
10. Fuel + oxygen = carbon dioxide + water + energy.
11. The process where liquid water changes into water vapour due to heating.
14. The movement of water through soil and rock layers below the surface.
15. All living organisms on Earth and the environments in which they live.
16. The process where water vapour cools and changes into liquid water.
21. The average weather conditions of a region over a long period of time (usually 30 years or more).
23. The solid parts of Earth, including rocks, soil, landforms, and the Earth's interior.
24. Glucose + oxygen = carbon dioxide + water + energy.
