Key Science Terms and definitions covered in this textbook
  • Air mass

    A large body of air that is characterized by a sameness of temperature and humidity.

  • Alluvium

    Unconsolidated sediment deposited by a stream.

  • Angular unconformity

    An unconformity in which the strata below dip at an angle different from that of the beds above.

  • Aurora

    A bright display of ever-changing light caused by solar radiation interacting with the upper atmosphere in the region of the poles.

  • Barometer

    An instrument that measures atmospheric pressure.

  • Color

    A phenomenon of light by which otherwise identical objects may be differentiated.

  • Coral reef

    Structure formed in a warm, shallow, sunlit ocean environment that consists primarily of the calcite-rich remains of corals as well as the limy secretions of algae and the hard parts of many other small organisms.

  • Covalent bond

    A chemical bond produced by the sharing of electrons.

  • Freezing nuclei

    Solid particles that serve as cores for the formation of ice crystals.

  • Glacier

    A thick mass of ice originating on land from the compaction and recrystallization of snow that shows evidence of past or present flow.

  • Lava tube

    Tunnel in hardened lava that acts as a horizontal conduit for lava flowing from a volcanic vent. Lava tubes allow fluid lavas to advance great distances.

  • Lunar regolith

    A thin, gray layer on the surface of the Moon, consisting of loosely compacted, fragmented material believed to have been formed by repeated meteoritic impacts.

  • Magnitude (earthquake)

    The total amount of energy released during an earthquake.

  • Medial moraine

    A ridge of till formed when lateral moraines from two coalescing alpine glaciers join.

  • Oceanic zone

    The marine-life zone beyond the continental shelf.

  • Paleontology

    The systematic study of fossils and the history of life on Earth.

  • Partial melting

    The process by which most igneous rocks melt. Since individual minerals have different melting points, most igneous rocks melt over a temperature range of a few hundred degrees. If the liquid is squeezed out after some melting has occurred, a melt with a higher silica content results.

  • Psychrometer

    A device consisting of two thermometers (wet bulb and dry bulb) that is rapidly whirled and, with the use of tables, yields the relative humidity and dew point.

  • Relative humidity

    The ratio of the air’s watervapor content to its water-vapor capacity.

  • Secondary (S) wave

    A seismic wave that involves oscillation perpendicular to the direction of propagation.
