2nd Semester Vocab
Hydrosphere, chemical, physical, ect. vocabulary words.
| Term | Definition |
|---|---|
| Mass | the amount of matter in an object |
| Weight | is a force due to the pull of gravity on an object. |
| Volume | is the amount of space occupied by a substance; size. |
| Density | is how much mass a material has per unit of volume. Denser materials have more matter in a given space than less dense materials. Density is found by dividing the mass of an object by its volume. |
| Appearance | is how something looks. |
| Odor | is the smell that a substance gives off. For example, vinegar has a pungent odor. |
| Texture | is how a substance feels to the touch. For example, sand has a grainy texture, while talc has a soft, fine texture. |
| Boiling Point | is the temperature at which a liquid changes to a gas. For water, it is 100 °C or 212 °F. |
| Melting/Freezing Point | is the temperature at which a liquid changes from a solid to a liquid. For water, it is 0 °C or 32 °F |
| Solubility | refers to the ability of a substance to dissolve in a solvent such as water or the amount of a substance that can dissolve in a certain amount of water. |
| Polarity | The distribution of electrical charge within a molecule of a substance. |
| Viscosity | refers to how easily a liquid is able to flow. |
| Conductivity | refers to the ability of a substance to transmit energy |
| Compressibility | refers to the ability of a given mass of a substance to decrease in volume in response to the application of an outside force. |
| Magnetism | The ability of a substance to respond to a magnetic field. |
| Reactivity | describes whether a substance reacts easily with other substances. For example, most metals will react with acids. |
| Unreactive Substance | substance does not react easily with most other substances. The noble gases are the least reactive elements |
| Flammability | describes the ability of a substance to ignite or burn |
| Combustibility | describes the ability of a substance to react rapidly with oxygen and release energy in the form of heat and/or light. |
| Natural Resources | materials from thr enviorment that are used by living things |
| Respiration | oxegyn is used to release the energy stored in food |
| Photosynthesis | a process by which some organisms use light energy from the sun to make nutrients in the form of carbohydrates |
| Desalination | seperates salt from seawater |
| Oceanography | the study of physical properties of oceans |
| Sonar | Sound Navigation And Ranging |
| benthos | organisms that live on or near the bottom of the ocean |
| plankton | tiny organisms that are moved by ocean currents |
| nekton | free-swimming organisms organsims that move independantly of currents |
| intertidal zone | the shoreline area that falls between the hightide mark & the low tide mark |
| neritic zone | the ocean area that slopes down from the edge of the shoreline toward the ocean floor |
| coral reef | a limestone deposit formed from coral shells |
| upwelling | the movement of nutrient rich waters from the deep ocean into shallow areas |
| oceanic zone | made up of the open waters of the ocean |
| hydothermal vents | cracks in the ocean crust that release mineral rich water that has been heated by Earth's interior |
| estuaries | are a unique ecosystem that forms where salty ocean water mixes with fresh water from rivers |
| photosynthesis | a food making process in which organisms use the energy in sunlight to combine carbon dioxide and water to produce sugars & oxegyn |
| consumer | an organism that obtains its food by eating other organisms |
| producer | an organism that makes its own food |
| decomposer | an organism that gets its food & energy by breaking down the remains of dead organisms |
| trophic level | each feeding level in an ecosystem is called a tropic level |
| food web | a diagram to show the interconnected network of food chains within an ecosystem |
| food chain | show the flow of energy from producer to different levels of consumers to decomposers |
| pH | measures how acidic or basic water is |
| turbidity | a measure of how clear water is |
| algal bloom | rapid growth of algae ecouraged by too many nutrients in the water |
| nitrates | nitrogen compounds used for growth by plants and algae |
| bioindicators | organisms or parts of organisms that are used to acsess ecosystem health |
| pollutant | any substance or form of energy that can cause harm to the environment and make it unfit for use by organisms |
| point-source pollution | pollution that comes from a single identifiable source |
| non-point-source pollution | pollution that comes from many places or a source that isn't easily identified |
| wastewater | water that runs into drains |
| wastewater treatment plant | a facility that processes water to remove wastes & then releases the clean water into a lake or stream |
| drain feild | a series of pipes that are buried under gravel or crushed rocks |
| septic system | a wastewater treatment system for an individual home or farm |
