| Question | Answer |
|---|---|
| alluvium | loose sediment deposited by a stream |
| aquifer | a bed of rock permeable to underground water |
| atmospheric pressure | the pressure exerted by the weight of the air lying directly above the area; at sea level, about 15 lbs. per square inch |
| basalt | an igneous rock formed from lava |
| cloud | a collection of tiny water or ice droplets sufficiently numerous to be seen |
| coal | a rock composed of partly decayed and compressed plant material |
| conglomerate | a sedimentary rock consisting of pebbles cemented together |
| continental drift | the hypothesis of continents moving laterally |
| crust | the thin outer zone of the earth above the mantle |
| cyclone | a low-pressure area around which winds blow counterclockwise in the Northern Hemisphere |
| delta | a triangular deposit of sediment at the mouth of a river |
| erosion | the removal of rock debris by water, ice, and wind |
| evaporation | the process by which a liquid changes to a gas; specifically, when water changes to water vapor |
| extrusive | igneous rock of volcanic origin |
| fault | a planar break in rock along which displacement has occurred |
| fold | bent or warped rock layers |
| front | the boundary between two air masses of different temperature; a common site for cloud formation and precipitation |
| geothermal energy | heat obtained from hot water or steam within the earth |
| igneous | rock formed by the solidification of molten rock material |
| intrusive | igneous rock crystallized beneath the surface of the earth |
| karst | pitted topography due to solution of limestone |
| laterite | iron-rich soil caused by tropical weathering |
| lava | molten rock extruded from a volcano |
| limestone | sedimentary rock composed of calcium carbonate |
| lithification | the consolidation of loose sediment |
| lithology | rock type |
| magma | molten rock within the earth |
| mantle | the zone of the earth between the core and the crust |
| metamorphic | rock formed by the transformation, under high temperature and pressure, of older sedimentary or igneous rock |
| mineral | a naturally occurring inorganic chemical compound |
| paleontology | the science of fossil life |
| permafrost | ground that is frozen throughout the year |
| petroleum | a liquid fuel from the transformation of plant and animal remains |
| plutonic | igneous rock that has crystallized beneath the earth's surface, as opposed to volcanic rock |
| precipitation | any form of water, whether liquid or solid particles, that falls from the atmosphere; rain, sleet, snow, or hail |
| rainbow | a circular arc of colored bands produced by the refraction and reflection of sunlight by a sheet of raindrops. The sun must be behind the observer |
| sedimentary | rock formed by deposition at the earth's surface |
| specific gravity | relative density;the density of a substance divided by the density of water, which therefore has a specific gravity of 1 |
| stalactite | a cone of calcarous rock hanging fromt he roof of a cavern |
| stalagmite | a pillar of calcareous rock rising from the floor of a cavern |
| strata | layers of sedimentary rock;singular form is stratum |
| stratosphere | the atmospheric shell above the troposphere; the stratosphere extends from 6 to 30 miles above the earth's surface |
| syncline | the trough of a rock fold |
| tectonic | refers to movements of the earth's crust |
| troposphere | the lowest six miles of the atmosphere, characterized by temperature decreasing with height |
| water table | the upper limit of groundwater, below which all pores in the rocks are filled with water |
| weathering | the physical and chemical destruction of rock by the atmosphere |
