Key Science Terms and definitions covered in this textbook
  • Absolute instability

    Air that has a lapse rate greater than the dry adiabatic rate.

  • Chemical sedimentary rock

    Sedimentary rock consisting of material that was precipitated from water by either inorganic or organic means.

  • Cross-cutting

    A principle of relative dating. A rock or fault is younger than any rock (or fault) through which it cuts.

  • Earth system science

    An interdisciplinary study that seeks to examine Earth as a system composed of numerous interacting parts or subsystems.

  • Ice cap climate

    A climate that has no monthly means above freezing and supports no vegetative cover except in a few scattered high mountain areas. This climate, with its perpetual ice and snow, is confined largely to the ice sheets of Greenland and Antarctica.

  • Inner core

    The solid innermost layer of Earth, about 1,300 kilometers (800 miles) in radius.

  • Intraplate volcanism

    Igneous activity that occurs within a tectonic plate away from plate boundaries.

  • Lateral moraine

    A ridge of till along the sides of an alpine glacier composed primarily of debris that fell to the glacier from the valley walls.

  • Loess

    Deposits of windblown silt, lacking visible layers, generally buff-colored, and capable of maintaining a nearly vertical cliff.

  • Low

    A center of low pressure characterized by cyclonic winds.

  • Mohs scale

    A series of 10 minerals used as a standard in determining hardness.

  • Oceanography

    The scientific study of the oceans and oceanic phenomena.

  • Orogenesis

    The processes that collectively result in the formation of mountains.

  • Oxbow lake

    A curved lake produced when a stream cuts off a meander.

  • Pluvial lake

    A lake formed during a period of increased rainfall. During the Pleistocene epoch this occurred in some nonglaciated regions during periods of ice advance elsewhere.

  • Prevailing wind

    A wind that consistently blows from one direction more than from another.

  • Radioactive decay

    The spontaneous decay of certain unstable atomic nuclei.

  • Relative humidity

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

  • Sediment

    Unconsolidated particles created by the weathering and erosion of rock, by chemical precipitation from solution in water, or from the secretions of organisms and transported by water, wind, or glaciers.

  • Tarn

    A small lake in a cirque.
