Key Science Terms and definitions covered in this textbook
  • Circle of illumination

    The great circle that separates daylight from darkness.

  • Continental rift

    A linear zone along which continental lithosphere stretches and pulls apart. Its creation may mark the beginning of a new ocean basin.

  • Convection

    The transfer of heat by the movement of a mass or substance. It can take place only in fluids.

  • Ductile deformation

    A type of solid state flow that produces a change in the size and shape of a rock body without fracturing. Occurs at depths where temperatures and confining pressures are high.

  • El Niño

    The name given to the periodic warming of the ocean that occurs in the central and eastern Pacific. A major El Niño episode can cause extreme weather in many parts of the world.

  • Evaporite deposits

    A sedimentary rock formed of material deposited from solution by evaporation of water.

  • Foliation

    A texture of metamorphic rocks that gives the rock a layered appearance.

  • Geothermal gradient

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

  • Glacial drift

    An all-embracing term for sediments of glacial origin, no matter how, where, or in what shape they were deposited.

  • Graded bed

    A sediment layer that is characterized by a decrease in sediment size from bottom to top.

  • Hydrogen fusion

    The nuclear reaction in which hydrogen nuclei are fused into helium nuclei.

  • Low

    A center of low pressure characterized by cyclonic winds.

  • Magnitude (stellar)

    A number given to a celestial object to express its relative brightness.

  • Maritime (m) air mass

    An air mass that originates over the ocean. These air masses are relatively humid.

  • Mixing ratio

    The mass of water vapor in a unit mass of dry air; commonly expressed as grams of water vapor per kilogram of dry air.

  • Nonsilicates

    Mineral groups that lack silicas in their structures and account for less than 10 percent of Earth’s crust.

  • Radioactivity

    The spontaneous emission of certain unstable atomic nuclei.

  • Spring equinox

    The equinox that occurs on March 21–22 in the Northern Hemisphere and on September 21–23 in the Southern Hemisphere.

  • Stratified drift

    Sediments deposited by glacial meltwater.

  • Tropopause

    The boundary between the troposphere and the stratosphere.
