The apparent brightness of a star if it were viewed from a distance of 10 parsecs (32.6 light-years). Used to compare the true brightness of stars.
Andean-type plate margin
Plate boundaries that generate continental volcanic arcs.
Angle of repose
The steepest angle at which loose material remains stationary without sliding downslope.
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.
Solar energy scattered and reflected in the atmosphere that reaches Earth’s surface in the form of diffuse blue light from the sky.
The land area that contributes water to a stream.
Sinuous ridge composed largely of sand and gravel deposited by a stream flowing in a tunnel beneath a glacier near its terminus.
A tributary valley that enters a glacial trough at a considerable height above its floor.
A nearshore current that flows parallel to the shore.
The process of generating more than one rock type from a single magma.
Negative feedback mechanism
A feedback mechanism that tends to maintain a system as it is—that is, maintain the status quo.
Atoms combine in order that each may have the electron arrangement of a noble gas; that is, the outer energy level contains eight neutrons.
One in which both matter and energy flow into and out of the system. Most natural systems are of this type.
A molecule of oxygen containing three oxygen atoms.
The upper part of the ocean into which any sunlight penetrates.
Metamorphism associated with large-scale mountain-building processes.
A local wind blowing from the sea during the afternoon in coastal areas.
A linear downfold in sedimentary strata; the opposite of anticline.
A flat, benchlike structure produced by a stream, which was left elevated as the stream cut downward.
