A glacier confined to a mountain valley, which in most instances had previously been a stream valley.
A term used to describe intrusive igneous masses that form parallel to the bedding of the surrounding rock.
Coriolis force (effect)
The deflective force of Earth’s rotation on all free-moving objects, including the atmosphere and oceans. Deflection is to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
The depression at the summit of a volcano, or that which is produced by a meteorite impact.
Very small galaxies, usually elliptical and lacking spiral arms.
A submerged flat-topped seamount.
Igneous rock that formed below Earth’s surface.
The brightness of a star. The amount of energy radiated by a star.
A star of extremely high density composed entirely of neutrons.
A front formed when a cold front overtakes a warm front. It marks the beginning of the end of a middle-latitude cyclone.
One in which both matter and energy flow into and out of the system. Most natural systems are of this type.
Refers to the cells or organisms such as bacteria whose genetic material is not enclosed in a nucleus.
Ground-up rock produced by the grinding effect of a glacier.
The zone between 104 and 143 degrees distance from an earthquake epicenter in which direct waves do not arrive because of refraction by Earth’s core.
An instrument for directly viewing the spectrum of a light source.
A coast with a form that is largely the result of the partial drowning of a former land surface either because of a rise of sea level or subsidence of the crust or both.
An accumulation of rock debris at the base of a cliff.
A crustal block bounded by faults, whose geologic history is distinct from the histories of adjoining crustal blocks.
Red giants that overshoot equilibrium, then alternately expand and contract.
The disintegration and decomposition of rock at or near Earth’s surface.
