| Question | Answer |
|---|---|
| Astronomy | the study of the universe. |
| Atmosphere | A life-living gaseous envelope that surrounds the earth. |
| Biosphere | includes all life on earth |
| Closed System | system that is self-contained with regard to matter |
| Core | is the denser inner sphere |
| Crust | is the light and very thin outer skin of Earth |
| Earth Science | subject of our text |
| Earth Science system | aims to study Earth as a system composed of numerous interacting parts, or subsystems. |
| Environment | is everything that surrounds and influences an organism |
| Geology | the study of earth |
| Hydrosphere | is a dynamic mass of liquid that is continually on the move, evaporating from the oceans to the atmosphere, precipitating to the land, and running back into the ocean again. |
| Hypothesis | A constructed explanation |
| Lithosphere | is the rigid outer layer of Earth that includes the crust and and uppermost mantle. |
| Mantle | less dense sphere, less dense than core |
| Meteorology | is the study of the atmosphere and the processes that produce weather and climate. |
| Model | looser term for hypothesis |
| Nebular Hypothesis | suggests that the bodies of our solar system evolved from an enormous revolving cloud called the solar nebula, composed of mostly hydrogen and helium with smaller percentages of the heavier elements. |
| Negative Feedback Mechanism | works to maintain the system as it is |
| Nonrenewable Resource | many basic resources classify as this, such as; iron, aluminum,copper, oil, natural gas,and coal |
| Oceanography | study of the oceans in all their aspects and relationships |
| Open System | both energy and matter flow into and out of the system, |
| Paradigm | explain a large number of interrelated aspects of the natural world |
| Physical Environment | encompasses water, air, soil, and rock. Some are biological and social, others are nonliving. |
| Positive Feedback Mechanism | mechanisms that enhance or drive change |
| Renewable Resource | Can be replenished over relatively short time spans. |
| System | can be any size group of interacting parts that form a complex whole. |
| Theory | an elevated hypothesis, when competing models have been eliminated. |
