Key Science Terms and definitions covered in this textbook
  • Bergeron process

    A theory that relates the formation of precipitation to supercooled clouds, freezing nuclei, and the different saturation levels of ice and liquid water.

  • Calving

    Wastage of a glacier that occurs when large pieces of ice break off into water.

  • Collision–coalescence process

    A theory of raindrop formation in warm clouds (above 0° C) in which large cloud droplets (giants) collide and join together with smaller droplets to form a raindrop. Opposite electrical charges may bind the cloud droplets together.

  • Coriolis force (effect)

    The deflective force of Earth’s rotation on all free-moving objects, including the atmosphere and oceans. Deflection is to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

  • Detrital sedimentary rock

    Rock formed from the accumulation of material that originated and was transported in the form of solid particles derived from both mechanical and chemical weathering.

  • Dry climate

    A climate in which yearly precipitation is not as great as the potential loss of water by evaporation.

  • Elliptical galaxy

    A galaxy that is round or elliptical in outline. It contains little gas and dust, no disk or spiral arms, and few hot, bright stars.

  • Esker

    Sinuous ridge composed largely of sand and gravel deposited by a stream flowing in a tunnel beneath a glacier near its terminus.

  • Geothermal gradient

    The gradual increase in temperature with depth in the crust. The average is 30° C per kilometer in the upper crust.

  • Glacial striations

    Scratches and grooves on bedrock caused by glacial abrasion.

  • Lunar highlands

    See Terrae.

  • Mixed tidal pattern

    A tidal pattern exhibiting two high tides and two low tides per tidal day with a large inequality in high water heights, low water heights, or both. Coastal locations that experience such a tidal pattern may also show alternating periods of diurnal and semidiurnal tidal patterns. Also called mixed semidiurnal.

  • Nekton

    Pelagic organisms that can move independently of ocean currents by swimming or other means of propulsion.

  • Nuclear fusion

    The source of the Sun’s energy.

  • Protoplanets

    A developing planetary body that grows by the accumulation of planetesimals.

  • Rain

    Drops of water that fall from clouds that have a diameter of at least 0.5 millimeter (0.02 inch).

  • Red giant

    A large, cool star of high luminosity; a star occupying the upper-right portion of the Hertzsprung-Russell diagram.

  • Settling velocity

    The speed at which a particle falls through a still fluid. The size, shape, and specific gravity of particles influence settling velocity.

  • Subarctic climate

    A climate found north of the humid continental climate and south of the polar climate and characterized by bitterly cold winters and short, cool summers. Places within this climatic realm experience the highest annual temperature ranges on Earth.

  • Syncline

    A linear downfold in sedimentary strata; the opposite of anticline.
