A cloud of glowing gas excited by ultraviolet radiation from hot stars.
An isotope resulting from radioactive decay.
A cone-shaped deposit at the base of the continental slope. The sediment is transported to the fan by turbidity currents that follow submarine canyons.
Very small galaxies, usually elliptical and lacking spiral arms.
A galaxy that is round or elliptical in outline. It contains little gas and dust, no disk or spiral arms, and few hot, bright stars.
Displacement along a fault that is so slow and gradual that little seismic activity occurs.
A sudden brightening of an area on the Sun.
A topography consisting of numerous depressions called sinkholes.
Lapse rate (normal)
The average drop in temperature (6.5° C per kilometer; 3.5° F per 1,000 feet) with increased altitude in the troposphere.
The marine-life zone that extends from the low tideline out to the shelf break.
Nonmetallic mineral resource
Mineral resource that is not a fuel or processed for the metals it contains.
Resource that forms or accumulates over such long time spans that it must be considered as fixed in total quantity.
The systematic study of fossils and the history of life on Earth.
Those pollutants emitted directly from identifiable sources.
A long, narrow trough bounded by normal faults. It represents a region where divergence is taking place.
The redirecting (in all directions) of light by small particles and gas molecules in the atmosphere. The result is diffused light.
A mechanism that contributes to plate motion in which cool, dense oceanic crust sinks into the mantle and “pulls” the trailing lithosphere along.
A soil classification system consisting of six hierarchical categories based on observable soil characteristics. The system recognizes 12 soil orders.
The uppermost layer in a soil profile: the A horizon.
