A mixture of many discrete gases, of which nitrogen and oxygen are most abundant, in which varying quantities of tiny solid and liquid particles are suspended.
Banded iron formations
A finely layered iron and silica-rich (chert) layer deposited mainly during the Precambrian.
Seafloor sediments consisting of material of marine-organic origin.
A structure protecting a nearshore area from breaking waves.
A boundary in which two plates move together, causing one of the slabs of lithosphere to be consumed into the mantle as it descends beneath on an overriding plate.
The portion of seafloor that lies between the continental margin and the oceanic ridge system. This region comprises almost 30 percent of Earth’s surface.
A section of a stream that leaves the main flow.
A ridge of till marking a former position of the front of a glacier.
That portion of the shore lying between the normal high and low water marks; the intertidal zone.
Fog formed when rain evaporates as it falls through a layer of cool air.
A vent in a volcanic area from which fumes or gases escape.
A sequence of stars on the Hertzsprung-Russell diagram, containing the majority of stars, that runs diagonally from the upper left to the lower right.
A naturally occurring, inorganic crystalline material with a unique chemical composition.
A crescent-shaped accumulation of sand and gravel deposited on the inside of a meander.
The spontaneous decay of certain unstable atomic nuclei.
An elongated ridge of sand that projects from the land into the mouth of an adjacent bay.
The uppermost layer in a soil profile: the A horizon.
The lowermost layer of the atmosphere. It is generally characterized by a decrease in temperature with height.
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.
A relatively narrow body of stratified drift deposited on a valley floor by meltwater streams that issue from a valley glacier.
