Key Science Terms and definitions covered in this textbook
  • Barchan dune

    A solitary sand dune shaped like a crescent with its tips pointing downward.

  • Carbonate group

    Mineral group whose members contain the carbonate ion and one or more kinds of positive ions. Calcite is a common example.

  • Climate

    A description of aggregate weather conditions; the sum of all statistical weather information that helps describe a place or region.

  • Gondwanaland

    The southern portion of Pangaea consisting of South America, Africa, Australia, India, and Antarctica.

  • Impact craters

    Depressions that are the result of collisions with bodies such as asteroids and comets.

  • Inertia

    A property of matter that resists a change in its motion.

  • Lake-effect snow

    Snow showers associated with a cP air mass to which moisture and heat are added from below as the air mass traverses a large and relatively warm lake (such as one of the Great Lakes), rendering the air mass humid and unstable.

  • Land breeze

    A local wind blowing from land toward the water during the night in coastal areas.

  • Magnitude (stellar)

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

  • Mineral resource

    All discovered and undiscovered deposits of a useful mineral that can be extracted now or at some time in the future.

  • 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.

  • Nekton

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

  • Reflection

    The process whereby light bounces back from an object at the same angle at which it encounters a surface and with the same intensity.

  • Slide

    A movement common to mass-wasting processes in which the material moving downslope remains fairly coherent and moves along a well-defined surface.

  • Spectroscope

    An instrument for directly viewing the spectrum of a light source.

  • Stationary front

    A situation in which the surface position of a front does not move; the flow on either side of such a boundary is nearly parallel to the position of the front.

  • Stratosphere

    The layer of the atmosphere immediately above the troposphere, characterized by increasing temperatures with height, owing to the concentration of ozone.

  • Supercontinent cycle

    The idea that the rifting and dispersal of one supercontinent is followed by a long period during which the fragments gradually reassemble into a new supercontinent.

  • Supercooled

    The condition of water droplets that remain in the liquid state at temperatures well below 0° C.

  • Thunderstorm

    A storm produced by a cumulonimbus cloud and always accompanied by lightning and thunder. It is of relatively short duration and usually accompanied by strong wind gusts, heavy rain, and sometimes hail.
