Active continental margin
Usually narrow and consisting of highly deformed sediments. They occur where oceanic lithosphere is being subducted beneath the margin of a continent.
Annual temperature range
The difference between the highest and lowest monthly temperature means.
The wet, sloping surface that extends from the berm to the shoreline.
Zone of inclined seismic activity that extends from a trench downward into the asthenosphere.
The gently sloping surface at the base of the continental slope.
A stream system that resembles the pattern of a branching tree.
A section of a stream that leaves the main flow.
Celestial bodies that orbit stars, massive enough to be spherical but have not cleared their neighboring regions of planetesimals.
A sedimentary rock formed of material deposited from solution by evaporation of water.
The tidal current associated with the increase in the height of the tide.
A luminous star of large radius.
Compensation of the lithosphere when weight is added or removed. When weight is added, the lithosphere will respond by subsiding, and when weight is removed, there will be uplift.
Varieties of the same element that have different mass numbers; their nuclei contain the same number of protons but different numbers of neutrons.
The rigid outer layer of Earth, including the crust and upper mantle.
Longitudinal (seif dunes)
Long ridges of sand oriented parallel to the prevailing wind; these dunes form where sand supplies are limited.
A chemical bond present in all metals that may be characterized as an extreme type of electron sharing in which the electrons move freely from atom to atom.
A star of extremely high density composed entirely of neutrons.
Atoms combine in order that each may have the electron arrangement of a noble gas; that is, the outer energy level contains eight neutrons.
The processes that collectively result in the formation of mountains.
The release of water vapor to the atmosphere by plants.
