A bright display of ever-changing light caused by solar radiation interacting with the upper atmosphere in the region of the poles.
A theory that originally proposed that the continents are rafted about. It has essentially been replaced by the plate tectonics theory.
Environmental lapse rate
The rate of temperature decrease with increasing height in the troposphere.
Evolution (Theory of)
A fundamental theory in biology and paleontology that sets forth the process by which members of a population of organisms come to differ from their ancestors. Organisms evolve by means of mutations, natural selection, and genetic factors. Modern species are descended from related but different species that lived in earlier times.
A type of movement common to mass-wasting processes that refers to the free falling of detached individual pieces of any size.
Geologic time scale
The division of Earth history into blocks of time—eons, eras, periods, and epochs. The time scale was created using relative dating principles.
An undulating layer of till deposited as the ice front retreats.
The time required for one-half of the atoms of a radioactive substance to decay.
Radiation with a wavelength from 0.7 to 200 micrometers.
Atoms combine in order that each may have the electron arrangement of a noble gas; that is, the outer energy level contains eight neutrons.
A flat area on the floor of an undrained desert basin. Following heavy rain, the playa becomes a lake.
Rocks are placed in their proper sequence or order. Only the chronological order of events is determined.
A time period based on the revolution of the Moon around Earth with respect to the stars.
The cloud of interstellar gas and/or dust from which the bodies of our solar system formed.
Slow, downslope flow of water-saturated materials common to permafrost areas.
See Composite cone.
Seafloor sediments derived from terrestrial weathering and erosion.
By international agreement, a tropical cyclone with maximum winds that do not exceed 61 kilometers (38 miles) per hour.
A downslope movement of dense, sediment-laden water created when sand and mud on the continental shelf and slope are dislodged and thrown into suspension.
The upper level of the saturated zone of groundwater.
