Across
- 3. Density, a function of temperature, salinity, and pressure.
- 4. the ability or tendency to float in water or in air or in another type of fluid.
- 8. Pressure, the pressure that any fluid in a confined space excerpts.
- 11. Circulation, the movement of ocean currents due to differences in temperature and salinity in different regions of water.
- 13. the average kinetic energy of the particles in a substance. Measured in degrees (C,K,F) usually with a thermometer.
- 14. an animal that is dependent on or capable of internally generating heat; warm-blooded animals.
- 16. an organism that maintains their body temperature at a constant level, usually above that of the environment, by its metabolic activity.
- 17. zone, the region that is in complete darkness in the ocean.
- 20. the resistance of a fluid to change in shape or movement of neighboring portions relative to another.
- 21. the location of objects by reflected sound, used by animals like dolphins.
- 22. animals that have a body temperature similar to their surrounding environment.
- 23. Principle, a result stating that a body totally or partially immersed in a fluid is subject to an upward force equal in magnitude to the weight of fluid it displaces.
Down
- 1. a steep temperature gradient in a body of water marked by a layer above and below which the water is at different temperatures.
- 2. the quality or state of being saline; salty.
- 5. zone, the uppermost layer of a body of water; where sunlight can reach.
- 6. a layer in the ocean or a body of water where water density increases rapidly with depth.
- 7. the force of an object that resists its motion through a fluid.
- 9. the total kinetic energy, in calories, of all the particles in a substance or object.
- 10. continuous physical force exerted on or against an object by something in contact with it.
- 12. Capacity, the ratio of heat absorbed by a material to the temperature change.
- 13. inertia, property of a material expresses the degree of slowness with which its temperature reaches that of the environment.
- 15. the chemical reactions in the body’s cells that change food into energy.
- 18. zone, the layer below the photic zone where only a small percentage of light reaches.
- 19. a form of coloration in which the upper surfaces of the body are more darkly pigmented than the illuminated lower areas.
- 24. vertical zone in the oceanic water column where salinity changes rapidly with depth.
