Key Science Terms and definitions covered in this textbook
  • Asthenosphere

    A subdivision of the mantle situated below the lithosphere. This zone of weak material exists below a depth of about 100 kilometers and in some regions extends as deep as 700 kilometers. The rock within this zone is easily deformed.

  • Black dwarf

    A final state of evolution for a star, in which all of its energy sources are exhausted and it no longer emits radiation.

  • Dissolved load

    That portion of a stream’s load carried in solution.

  • Dune

    A hill or ridge of wind-deposited sand.

  • Freezing nuclei

    Solid particles that serve as cores for the formation of ice crystals.

  • Geostrophic wind

    A wind, usually above a height of 600 meters (2,000 feet), that blows parallel to the isobars.

  • Hydrosphere

    The water portion of our planet; one of the traditional subdivisions of Earth’s physical environment.

  • Lahar

    Mudflows on the slopes of volcanoes that result when unstable layers of ash and debris become saturated and flow downslope, usually following stream channels.

  • Lunar breccia

    A lunar rock formed when angular fragments and dust are welded together by the heat generated by the impact of a meteoroid.

  • Mechanical weathering

    The physical disintegration of rock, resulting in smaller fragments.

  • Microcontinents

    Relatively small fragments of continental crust that may lie above sea level, such as the island of Madagascar, or be submerged, as exemplified by the Campbell Plateau located near New Zealand.

  • Outgassing

    The escape of gases that had been dissolved in magma.

  • Phytoplankton

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

  • Positive feedback mechanism

    A feedback mechanism that enhances or drives change.

  • Prevailing wind

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

  • Pulsar

    A variable radio source of small size that emits radio pulses in very regular periods.

  • Pyroclastic flow

    A highly heated mixture, largely of ash and pumice fragments, traveling down the flanks of a volcano or along the surface of the ground.

  • Rip current

    A strong narrow surface or nearsurface current of short duration and high speed flowing seaward through the breaker zone at nearly right angles to the shore. It represents the return to the ocean of water that has been piled up on the shore by incoming waves.

  • Specific gravity

    The ratio of a substance’s weight to the weight of an equal volume of water.

  • Tenacity

    Describes a mineral’s toughness or its resistance to breaking or deforming.
