Daily temperature range
The difference between the maximum and minimum temperatures for a day.
The apparent change in wavelength of radiation caused by the relative motions of the source and the observer.
A coast where land that was formerly below sea level has been exposed either because of crustal uplift or a drop in sea level or both.
A type of movement common to masswasting processes in which water-saturated material moves downslope as a viscous fluid.
The fine structure visible on the solar surface caused by convective cells below.
A piece of one rock unit contained within another. Inclusions are used in relative dating. The rock mass adjacent to the one containing the inclusion must have been there first in order to provide the fragment.
A sudden flash of light generated by the flow of electrons between oppositely charged parts of a cumulonimbus cloud or between the cloud and the ground.
A cloud occupying the height range from 2,000 to 6,000 meters.
Resource that forms or accumulates over such long time spans that it must be considered as fixed in total quantity.
A basic unit of the geologic calendar that is a subdivision of an era. Periods may be divided into smaller units called epochs.
A layer of water in which there is a rapid change of density with depth.
A mechanism that contributes to plate motion in which cool, dense oceanic crust sinks into the mantle and “pulls” the trailing lithosphere along.
The downward slipping of a mass of rock or unconsolidated material moving as a unit along a curved surface.
A solid form of precipitation produced by sublimination of water vapor.
Lower limit of perennial snow.
A situation in which the surface position of a front does not move; the flow on either side of such a boundary is nearly parallel to the position of the front.
The conversion of a solid directly to a gas without passing through the liquid state.
Movements of ocean water caused by density differences brought about by variations in temperature and salinity.
The concept that the processes that have shaped Earth in the geologic past are essentially the same as those operating today
