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.
A sequence of numbers that approximates the mean distances of the planets from the Sun.
Mountains in which great horizontal forces have shortened and thickened the crust. Most major mountain belts are of this type.
Solar energy scattered and reflected in the atmosphere that reaches Earth’s surface in the form of diffuse blue light from the sky.
A fault in which the movement is parallel to the dip of the fault.
A group of interrelated food chains.
Scratches and grooves on bedrock caused by glacial abrasion.
A dense, dark nebula thought to be the birthplace of stars.
The slope of a stream; generally measured in feet per mile.
A narrow, sharp-crested ridge formed by the upturned edge of a steeply dipping bed of resistant rock.
The process, generally cementation and/or compaction, of converting sediments to solid rock.
The overtaking of one front by another.
Layers of sediments are generally deposited in a horizontal or nearly horizontal position.
A local wind blowing from the sea during the afternoon in coastal areas.
A segment of an active fault zone that has not experienced a major earthquake over a span when most other segments have. Such segments are probable sites for future major earthquakes.
Frozen or semifrozen rain formed when raindrops freeze as they pass through a layer of cold air.
A pluton similar to but smaller than a batholith.
See Composite cone.
Any size group of interacting parts that form a complex whole.
A cobble or pebble polished and shaped by the sandblasting effect of wind.
