Key Science Terms and definitions covered in this textbook
  • Altitude (of the Sun)

    The angle of the Sun above the horizon.

  • 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.

  • Atom

    The smallest particle that exists as an element.

  • Baymouth bar

    A sandbar that completely crosses a bay, sealing it off from the open ocean.

  • Biogenous sediment

    Seafloor sediments consisting of material of marine-organic origin.

  • Catastrophism

    The concept that Earth was shaped by catastrophic events of a short-term nature.

  • Earth science

    The name for all the sciences that collectively seek to understand Earth. It includes geology, oceanography, meteorology, and astronomy.

  • Emission nebula

    A gaseous nebula that derives its visible light from the fluorescence of ultraviolet light from a star in or near the nebula.

  • Epicenter

    The location on Earth’s surface that lies directly above the focus of an earthquake.

  • Flood current

    The tidal current associated with the increase in the height of the tide.

  • Horizon

    A layer in a soil profile.

  • Land breeze

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

  • Paradigm

    A theory that is held with a very high degree of confidence and is comprehensive in scope.

  • Passive continental margin

    Margins that consist of a continental shelf, continental slope, and continental rise. They are not associated with plate boundaries and therefore experience little volcanism and few earthquakes.

  • Photochemical reaction

    A chemical reaction in the atmosphere that is triggered by sunlight, often yielding a secondary pollutant.

  • Pleistocene epoch

    An epoch of the Quaternary period beginning about 1.8 million years ago and ending about 10,000 years ago. Best known as a time of extensive continental glaciation.

  • Suspended load

    The fine sediment carried within the body of flowing water.

  • Tropic of Cancer

    The parallel of latitude, 231?2 degrees north latitude, marking the northern limit of the Sun’s vertical rays.

  • Turbulent flow

    The movement of water in an erratic fashion, often characterized by swirling, whirlpool-like eddies. Most streamflow is of this type.

  • Unstable air

    Air that does not resist vertical displacement. If it is lifted, its temperature will not cool as rapidly as the surrounding environment, so it will continue to rise on its own.
