Rock or soil through which groundwater moves easily.

The average of the atomic masses of isotopes for a given element.

A massive star that has collapsed to such a small volume that its gravity prevents the escape of all radiation.

A quasi-horizontal chonolith composed of anastomosing ductoliths, whose distal ends curl like a harpolith, thin like a sphenolith, or bulge discordantly like an akmolith or ethmolith.

A linear zone along which continental lithosphere stretches and pulls apart. Its creation may mark the beginning of a new ocean basin.

The difference between the maximum and minimum temperatures for a day.

The variation in the rate and degree of weathering caused by such factors as mineral makeup, degree of jointing, and climate.

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.

The conversion of hydrogen through fusion to form helium.

Radiation with a wavelength from 0.7 to 200 micrometers.

Fog resulting from radiation heat loss by Earth.

The spinning of a body, such as Earth, about its axis.

Water that flows over the land rather than infiltrating into the ground.

Highest tidal range that occurs near the times of the new and full moons.

That part of the craton that is mantled by relatively undeformed sedimentary rocks and underlain by a basement complex of igneous and metamorphic rocks.

A pluton similar to but smaller than a batholith.

The fine sediment carried within the body of flowing water.

Found almost exclusively in the Northern Hemisphere or at high altitudes in many mountainous regions. A treeless climatic realm of sedges, grasses, mosses, and lichens that is dominated by a long, bitterly cold winter.

That part of the total atmospheric pressure attributable to water-vapor content.

A measure of a fluid’s resistance to flow.
