| Question | Answer |
|---|---|
| Astronomy | The study of the universe. |
| Atmosphere | A life-giving gaseous envelope. |
| Biosphere | All life on Earth. |
| Closed System | Self-contained with regard to matter. |
| Core | A dense inner sphere. |
| Crust | The light and very thin outer skin of Earth. |
| Earth Science | The name for all the sciences that collectively seek to understand Earth and its neighbors in space. It includes geology, oceanography, meteorology, and astronomy. |
| Earth System Science | Aims to study Earth as a system composed of numerous interacting parts, or subsystems. |
| Environment | Refers to everything that surrounds and influences an organism. |
| Geology | Means study of Earth. Divided into two areas- physical and historical. |
| Hydrosphere | 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 to the ocean again. |
| Hypothesis | A tentative explanation. |
| Lithosphere | The rigid outer layer that includes the crust and uppermost mantle. |
| Mantle | The area less dense than the core. |
| Meteorology | The study of the atmosphere and the processes that produce weather and climate. |
| Model | Although often used synonymously with hypothesis, is a less precise term because it is sometimes used to describe a scientific theory as well. |
| Nebular Hypothesis | Suggests that the bodies of oursolar system evolved from an enormous rotating cloud called the solar nebula, composed mostly of hydrogen and helium, with a small percentage of the heavier elements. |
| Negative Feedback Mechanism | Work to maintain the system as it is, or in other words to maintain the status quo. |
| Nonrenewable Resource | The processes that create them are so slow that significant deposits take millions of years to accumulate. |
| Oceanography | Involves the application of all sciences in a comprehensive and interrelated 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 | The factors in the environment. |
| Positive Feedback Mechanism | Mechanisms that enhance or drive change. |
| Renewable Resource | Resources that can be replenished over relatively short time spans. |
| System | Can be any size group of interacting parts that form a complex whole. |
| Theory | A well-tested and widely accepted view that the scientific community agrees best exlains certain observable facts. |
