During the crystallization of magma, the earlier-formed minerals are denser than the liquid portion and settle to the bottom of the magma chamber.
The mean temperature for a day that is determined by averaging the 24 hourly readings or, more commonly, by averaging the maximum and minimum temperatures for a day.
A break in a rock mass along which movement has occurred.
A crack in rock along which there is a distinct separation.
A term found on some versions of the geologic time scale. It refers to the earliest interval (eon) of Earth history, and ended 4 billion years ago.
A fossil that is associated with a particular span of geologic time.
A pair of structures extending into the ocean at the entrance to a harbor or river that are built for the purpose of protecting against storm waves and sediment deposition.
The part of the mantle that extends from the core–mantle boundary to a depth of 660 kilometers.
A sensitive instrument used to measure the intensity of Earth’s magnetic field at various points.
A fault in which the rock above the fault plane has moved down relative to the rock below.
Oceanic ridge system
A continuous elevated zone on the floor of all the major ocean basins and varying in width from 500 to 5,000 kilometers (300–3,000 miles). The rifts at the crests of ridges represent divergent plate boundaries.
Polar (P) air mass
A cold air mass that forms in a high-latitude source region. Polar easterlies In the global pattern of prevailing winds, winds that blow from the polar high toward the subpolar low. These winds, however, should not be thought of as persistent winds, such as the trade winds.
A concentration of material above the solar surface that appears as a bright archlike structure.
Two or more radio telescopes that combine their signals to achieve the resolving power of a larger telescope.
The concentration of minor amounts of metals that are scattered through unweathered rock into economically valuable concentrations by weathering processes.
A flow of groundwater that emerges naturally at the ground surface.
A measure of stellar distance.
The central, completely dark part of a shadow produced during an eclipse.
