Earth and Earth Subsystems

3. The process by which plants convert sunlight, carbon dioxide, and water into energy and oxygen.
5. The process by which organisms convert oxygen and glucose into energy, releasing carbon dioxide and water.
8. The variety of life in the world or in a particular habitat or ecosystem.
9. The process of settling and accumulating particles, often forming sedimentary rock.
14. The rigid outer layer of Earth, including the crust and upper mantle.
17. The long-term pattern of weather conditions in a region, including temperature, humidity, and precipitation.
18. The frozen water part of the Earth system, including ice caps, glaciers, and sea ice.
19. Effect The trapping of heat in the Earth's atmosphere by greenhouse gases, contributing to global warming.

1. A community of living organisms and their interactions with the environment.
2. The layer of gases surrounding Earth, essential for life and weather patterns.
4. The solid part of Earth, consisting of rocks, minerals, and soil.
6. Layer A layer in the Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation.
7. A mixture of minerals, organic matter, water, and air that supports plant life.
8. All the living organisms on Earth, interacting with the lithosphere, hydrosphere, and atmosphere.
10. The breaking down of rocks and minerals by natural forces such as wind, water, and temperature changes.
11. Cycle The process by which carbon is exchanged between the Earth's atmosphere, oceans, biosphere, and geosphere.
12. Cycle The continuous movement of water on, above, and below the surface of the Earth.
13. Tectonics The theory explaining the movement of Earth's lithospheric plates and the associated phenomena like earthquakes and volcanism.
15. All the water on Earth's surface, including oceans, lakes, rivers, and glaciers.
16. The process by which soil and rock are removed from the Earth's surface by wind, water, or ice and transported elsewhere.
