Environmental Science
Across
- 2. a common method for testing a hypothesis.
- 4. Anything that takes up space and has mass.
- 6. Occurs when we use our senses (smell, sight, hearing, taste, touch) or an extension of our senses (microscope, tape, recorder, X-ray machine, and thermometer) to record an event.
- 9. Example of atmospheric science.
- 10. combinations of atoms, ions, or molecules.
- 12. is a widely accepted, plausible generalization about fundamental concepts in science that explains why things happen.
- 13. formed when two or more atoms or ions are bonded chemically.
- 14. A statement that provides a possible answer to a question or an explanation for an observation that can be tested.
- 17. Refers to multiple atoms.
- 19. The opposite of an acid in that it accepts hydrogen ions in solution.
- 21. is the study of energy.
- 23. the energy that cannot be used to do useful work.
- 24. It comprises all types of water resources oceans, seas, lakes, rivers, streams, reservoir, polar icecaps, glaciers, and ground water.
- 28. The phenomena where the environment’s temperature continues to warm.
- 30. Everything that affects an organism during its lifetime.
Down
- 1. It is the outer mantle of the solid earth.
- 3. The protective blanket of gases (N, O2, Ar, CO2, trace gases), surrounding the Earth.
- 5. tiny units that make up all matter in the universe, and energy is what holds the nucleus together.
- 7. A reaction when the newly formed chemical bonds contain more energy that was present in the compounds from which they were formed.
- 8. A process used to solve problems or develop an understanding of nature that involves testing possible answers.
- 11. Any compound that releases hydrogen ions (protons) in a solution.
- 15. Example of biological elements.
- 16. A substance that alters the rate of a reaction but does not consumed or altered in the process.
- 18. is a central characteristic of the scientific method.
- 20. The ability to do work.
- 22. It is done when an object is moved over a distance.
- 25. study of the interactions between life and its physical environment.
- 26. A pure substance
- 27. Evolution of Earth’s crust.
- 29. The vast majority of our people directly dependent on the nature resources of their country for their basic needs.
