A fan-shaped deposit of sediment formed when a stream’s slope is abruptly reduced.
A bright display of ever-changing light caused by solar radiation interacting with the upper atmosphere in the region of the poles.
The wet, sloping surface that extends from the berm to the shoreline.
A large group of stars.
A texture of metamorphic rocks that gives the rock a layered appearance.
A narrow, sharp-crested ridge formed by the upturned edge of a steeply dipping bed of resistant rock.
A line drawn on a map connecting points of equal atmospheric pressure, usually corrected to sea level.
The zone of beach that extends from the low-tide shoreline seaward to where waves break at low tide.
Mountains acting as barriers to the flow of air, forcing the air to ascend. The air cools adiabatically, and clouds and precipitation may result.
See Jovian planet.
A vertical conduit through which magmatic materials have passed.
The theory that proposes that Earth’s outer shell consists of individual plates that interact in various ways and thereby produce earthquakes, volcanoes, mountains, and the crust itself.
The motion of one body about another, as Earth about the Sun.
A model that illustrates the origin of the three basic rock types and the interrelatedness of Earth materials and processes.
The speed at which a particle falls through a still fluid. The size, shape, and specific gravity of particles influence settling velocity.
Seaward of the coast, this zone extends from the highest level of wave action during storms to the lowest tide level.
The force per unit area acting on any surface within a solid.
The process of thrusting oceanic lithosphere into the mantle along a convergent boundary.
In any undeformed sequence of sedimentary rocks, each bed is older than the layers above and younger than the layers below.
The vertical distance between the trough and crest of a wave.
