Rain or snow with a pH value that is less than the pH of unpolluted precipitation.
Sediment that is carried by a stream along the bottom of its channel.
Blowout (deflation hollow)
A depression excavated by the wind in easily eroded deposits.
The bright lines produced by an incandescent gas under low pressure.
A feature found in caves that is formed when a stalactite and stalagmite join.
One of three basic cloud forms; also the name given one of the clouds of vertical development. Cumulus are billowy individual cloud masses that often have flat bases.
The southern portion of Pangaea consisting of South America, Africa, Australia, India, and Antarctica.
Any form of artificial structure built to protect a coast or to prevent the movement of sand along a beach. Examples include groins, jetties, breakwaters, and seawalls.
A mass of glacial ice covering a high upland or plateau and spreading out radially.
Meandering channel that flows in a steep, narrow valley. They form either when an area is uplifted or when base level drops.
Tunnel in hardened lava that acts as a horizontal conduit for lava flowing from a volcanic vent. Lava tubes allow fluid lavas to advance great distances.
Longitudinal (seif dunes)
Long ridges of sand oriented parallel to the prevailing wind; these dunes form where sand supplies are limited.
A cloud occupying the height range from 2,000 to 6,000 meters.
A subatomic particle found in the nucleus of an atom. The neutron is electrically neutral and has a mass approximately that of a proton.
A curved lake produced when a stream cuts off a meander.
A device consisting of two thermometers (wet bulb and dry bulb) that is rapidly whirled and, with the use of tables, yields the relative humidity and dew point.
The apparent westward motion of the planets with respect to the stars.
An elongated ridge of sand that projects from the land into the mouth of an adjacent bay.
A seaward-facing cliff along a steep shoreline formed by wave erosion at its base and mass wasting
An instrument used to determine wind direction.
