Key Science Terms and definitions covered in this textbook
  • Cosmological red shift

    Changes in the spectra of galaxies that indicate they are moving away from the Milky Way as the result of the expansion of space.

  • Country breeze

    A circulation pattern characterized by a light wind blowing into a city from the surrounding countryside. It is best developed on clear and otherwise calm nights when the urban heat island is most pronounced.

  • Cross-cutting

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

  • Deep-ocean basin

    The portion of seafloor that lies between the continental margin and the oceanic ridge system. This region comprises almost 30 percent of Earth’s surface.

  • Divergent boundary

    A region where the rigid plates are moving apart, typified by the midoceanic ridges.

  • Emission spectrum

    See Bright-line spectrum

  • Era

    A major division on the geologic calendar; eras are divided into shorter units called periods.

  • Ground moraine

    An undulating layer of till deposited as the ice front retreats.

  • Hardness

    The resistance a mineral offers to scratching.

  • Hurricane

    A tropical cyclonic storm having winds in excess of 119 kilometers (74 miles) per hour.

  • Law of conservation of angular momentum

    The product of the velocity of an object around a center of rotation (axis), and the distance squared of the object from the axis is constant.

  • Lower mantle

    The part of the mantle that extends from the core–mantle boundary to a depth of 660 kilometers.

  • Magnitude (stellar)

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

  • Meteor shower

    Many meteors appearing in the sky caused when Earth intercepts a swarm of meteoritic particles.

  • Outer core

    A layer beneath the mantle about 2,200 kilometers (1,364 miles) thick that has the properties of a liquid.

  • Parasitic cone

    A volcanic cone that forms on the flank of a larger volcano.

  • Polar front

    The stormy frontal zone separating air masses of polar origin from air masses of tropical origin.

  • Summer solstice

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

  • Tornado watch

    A warning issued for areas of about 65,000 square kilometers (25,000 square miles), indicating that conditions are such that tornadoes may develop; it is intended to alert people to the possibility of tornadoes.

  • Troposphere

    The lowermost layer of the atmosphere. It is generally characterized by a decrease in temperature with height.
