Key Science Terms and definitions covered in this textbook
  • Basaltic composition

    A compositional group of igneous rocks indicating that the rock contains substantial dark silicate minerals and calciumrich plagioclase feldspar.

  • Body waves

    Seismic waves that travel through Earth’s interior.

  • Bright-line spectrum

    The bright lines produced by an incandescent gas under low pressure.

  • Conditional instability

    Moist air with a lapse rate between the dry and wet adiabatic rates.

  • Cone of depression

    A cone-shaped depression in the water table immediately surrounding a well.

  • Energy levels

    Spherically shaped, negatively charged zones that surround the nucleus of an atom.

  • Evaporite deposits

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

  • Fine-grained texture

    A texture of igneous rocks in which the crystals are too small for individual minerals to be distinguished with the unaided eye.

  • Habit

    Refers to the common or characteristic shape of a crystal, or aggregate of crystals.

  • Magnetometer

    A sensitive instrument used to measure the intensity of Earth’s magnetic field at various points.

  • Mantle

    The 2,900-kilometer- (1,800-mile-) thick layer of Earth located below the crust.

  • Neutron

    A subatomic particle found in the nucleus of an atom. The neutron is electrically neutral and has a mass approximately that of a proton.

  • Phytoplankton

    Algal plankton, which are the most important community of primary producers in the ocean.

  • 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.

  • Pyroclastic material

    The volcanic rock ejected during an eruption, including ash, bombs, and blocks.

  • Recessional moraine

    An end moraine formed as the ice front stagnated during glacial retreat.

  • Right ascension

    An angular distance measured eastward along the celestial equator from the vernal equinox. Used with declination in a coordinate system to describe the position of celestial bodies.

  • Sidereal day

    The period of Earth’s rotation with respect to the stars.

  • Travertine

    A form of limestone that is deposited by hot springs or as a cave deposit.

  • Winter solstice

    The solstice that occurs on December 21–22 in the Northern Hemisphere and on June 21–22 in the Southern Hemisphere.
