Across
- 4. Dependent Limiting Factor any force that affects the size of a population of living things in response to the density of the population (the number of individuals per unit area).
- 7. any single identifiable source of pollution from which pollutants are discharged, such as a pipe, ditch, ship or factory smokestack.
- 11. Population Growth takes place when a population's per capita growth rate stays the same, regardless of population size, making the population grow faster and faster as it gets larger.
- 12. Independent Limiting Factor any force that affects the size of a population of living things regardless of the density of the population (the number of individuals per unit area).
- 13. a horizontal movement of ocean water that is caused by wind and that occurs at or near the ocean's surface
- 14. the sequence of conditions through which water passes from vapor in the atmosphere through precipitation upon land or water surfaces and ultimately back into the atmosphere as a result of evaporation and transpiration
- 17. an animal establishes a home in a habitat because it has resources it can utilize or because the habitat is ideal for them.
- 18. the action of reducing the severity, seriousness, or painfulness of something.
- 19. generally results from land runoff, precipitation, atmospheric deposition, drainage, seepage, or hydrologic modification (rainfall and snowmelt) where tracing pollution back to a single source is difficult.
- 20. the cultivation of waste land or land formerly under water.
Down
- 1. any current in either a liquid or a gas that is kept in motion by the force of gravity acting on differences in density.
- 2. the heat required to raise the temperature of the unit mass of a given substance by a given amount (usually one degree).
- 3. the match of a species to a specific environmental condition.
- 5. an excavation or structure created in the ground by digging, driving, or drilling to access liquid resources, usually water.
- 6. a huge circle of moving ocean water found above and below the equator
- 8. a continuous, directed movement of sea water generated by a number of forces acting upon the water, including wind, the Coriolis effect, breaking waves, cabbeling, and temperature and salinity differences
- 9. a rising of seawater, magma, or other liquid.
- 10. to harvest (something) excessively and especially to a harmful degree
- 15. Population Growth expansion decreases as resources become scarce, leveling off when the carrying capacity of the environment is reached, resulting in an S-shaped curve.
- 16. an animal leaves its home because the habitat is no longer ideal for them and they need to find a more suitable environment.
