Across
- 3. The variable manipulated or changed by the researcher in an experiment to observe its effect on the dependent variable.
- 4. The cooling and conversion of water vapor into liquid form, forming clouds, typically occurring in the atmosphere.
- 5. The introduction of contaminants into the environment, disrupting natural balance.
- 8. The methods used to visually present data, such as graphs, charts, and tables, making it easier to interpret and draw conclusions.
- 10. The changes in biodiversity and habitats influenced by tectonic forces, such as the rise of mountain ranges.
- 11. The largest river system globally, influencing weather patterns and fostering diverse species.
- 14. A tropical wetland ecosystem in Florida, USA, known for its unique biodiversity.
- 17. The deepest and oldest freshwater lake in the world, located in Siberia, Russia.
- 18. Large pieces of Earth’s lithosphere that move and interact. Major plates include the Pacific Plate, North American Plate, Eurasian Plate, and others.
- 19. Inland bodies of water, typically larger and surrounded by land.
- 20. A region with a high level of seismic and volcanic activity surrounding the Pacific Ocean, influenced by tectonic plate interactions.
- 22. The flow of water across the land surface after precipitation, eventually making its way back to rivers, lakes, and oceans.
- 23. A testable and specific statement that predicts the outcome of an experiment, based on observation and previous knowledge.
- 24. The release of accumulated water droplets from clouds back to the Earth’s surface in the form of rain, snow, sleet, or hail.
- 25. Aquatic ecosystems with low salinity, including rivers, lakes, wetlands, and groundwater.
Down
- 1. The plan or layout of an experiment that outlines the procedures, variables, and controls used to obtain valid and reliable results.
- 2. The variable being observed or measured in an experiment, which responds to changes in the independent variable.
- 6. Ecosystems beneath the ocean’s surface, comprising living organisms, physical characteristics, and chemical properties.
- 7. Species with a disproportionate impact on the ecosystem, such as the beaver.
- 9. A divergent boundary in East Africa that has shaped unique landscapes and fostered diverse ecosystems.
- 12. The Earth’s central layer, a solid ball of iron and nickel. Despite extreme temperatures, it remains solid due to immense pressure.
- 13. An underground reservoir beneath the Great Plains of the United States.
- 15. Natural watercourses flowing towards an ocean, sea, lake, or another river.
- 16. Ground-shaking events caused by the sudden release of stress at plate boundaries, involving collisions, movements apart, or sliding past each other.
- 21. A major north-flowing river in northeastern Africa, historically vital for agriculture.
