A feldspar-rich sandstone.
An accumulation of sediment found along the landward margin of the ocean or a lake.
A cloud of glowing gas excited by ultraviolet radiation from hot stars.
A span on the geologic time scale beginning about 65 million years ago following the Mesozoic era.
The coast’s seaward edge. The landward limit of the effect of the highest storm waves on the shore.
Continental volcanic arc
Mountains formed in part by igneous activity associated with the subduction of oceanic lithosphere beneath a continent.
The transfer of heat by the movement of a mass or substance. It can take place only in fluids.
The condition that exists when the distribution of winds within a given area results in a net horizontal inflow of air into the area. Because convergence at lower levels is associated with an upward movement of air, areas of convergent winds are regions favorable to cloud formation and precipitation.
Melting that occurs as rock ascends due to a drop in confining pressure.
Mass per unit volume of a substance, usually expressed as grams per cubic centimeter
A gaseous nebula that derives its visible light from the fluorescence of ultraviolet light from a star in or near the nebula.
The initial velocity an object needs to escape from the surface of a celestial body.
A tilted fault block in which the higher side is associated with mountainous topography and the lower side is a basin that fills with sediment.
Deposit formed when heavy minerals are mechanically concentrated by currents, most commonly streams and waves. Placers are sources of gold, tin, platinum, diamonds, and other valuable minerals.
All geologic time prior to the Paleozoic era.
A segment of an active fault zone that has not experienced a major earthquake over a span when most other segments have. Such segments are probable sites for future major earthquakes.
The condition of water droplets that remain in the liquid state at temperatures well below 0° C.
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.
A measure of a fluid’s resistance to flow.
