Topics 1 and 2 Vocab for Earth Science Regents
| Question | Answer |
|---|---|
| universe | all matter, time, energy, and space |
| observation | the perception of some aspect of the environment by one or more of the human senses |
| instrument | a human-made device that extrends the sense beyond their normal limits |
| inference | and interpretation of an observation |
| classification | thr grouping together of similar things to make them more meaningful or easier to understand |
| measurement | a means of expressing an observation with greater accuracy (numerical value) |
| mass | the amount of matter in an object |
| volume | the amount of space an object occupies |
| percent deviation | the amount of error expressed as a percentage; percent deviation = difference from accepted value/accepted value x 100 |
| density | the concentration of matter in an object; density = mass/volume |
| rate of change | how much a measureable aspect of the environment is altered over a given time; rate of change = change in field value/change in time |
| cyclic change | events that constantly repeat and cause orderly change |
| prediction | a type of inference about the conditions and behavior of the environment in the future |
| natural hazard | a non-human related object, process or situation that has the possibility of causing loss of life, personal injury, or loss off property |
| interface | a boundary between regions with different properties over which energy is exchanged |
| dynamic equilibrium | environmental equilibrium resulting form oppositing forces or actions balancing out |
| natural resources | the materials and energy sources found in the environment that humans use in their deaily lives |
| pollution | occurs when the concentration of any substance or form of energy reaches a proportion that adversely affects people or their property or other life forms |
| model | a way of representing the properties of an object or system |
| atmosphere | the layer of gases that surrounds Earth above the surface of liquid water and rocky material |
| pauses | the interfaces or boundaries of the layers of Earth's atmosphere |
| hydrosphere | the layer of liquid water that lies between the atmosphere and much of the upper later of Earth's interior |
| lithosphere | the layers of rock that forms the solid outer shell at the top of Earth's interior |
| Earth's interior | the region extending from the rocky part of Earth's surface to Earth's center |
| coordinate system | the system for determining the coordinates of a point |
| latitude | the angular distance north or south of the equator |
| equator | the invisible line that marks the middle location on Earth's surface, halfway between the geographic North and South poles. |
| longitude | an angular distance east or west of the prime meridian |
| meridian of longitude | any semicircle on the Earth's surface connecting the north and south poles |
| prime meridian | the meridian of zero longitude |
| field | any region of space or the environment that has some measurable value of a given quantity at every point |
| isolines | lines that connect points of equal field values |
| contour lines | isolines that connect points of equal elevation |
| gradient | the rate of change from place to place within the field, or slope; gradient = change in field value/change in distance |
| topographic map | a commonly used model of the elevation field of the surface of Earth, also called a contour map |
| elevation | the vertical distance or height above or below sea level |
| profile | the side view of an area's landscape |
