Altitude (of the Sun)
The angle of the Sun above the horizon.
Impermeable beds that hinder or prevent groundwater movement.
A cloud of interstellar dust that obscures the light of more distant stars and appears as an opaque curtain.
The variation in the rate and degree of weathering caused by such factors as mineral makeup, degree of jointing, and climate.
A term used to describe plutons that cut across existing rock structures, such as bedding planes.
An all-embracing term for sediments of glacial origin, no matter how, where, or in what shape they were deposited.
The water portion of our planet; one of the traditional subdivisions of Earth’s physical environment.
A tentative explanation that is tested to determine if it is valid.
Lapse rate (normal)
The average drop in temperature (6.5° C per kilometer; 3.5° F per 1,000 feet) with increased altitude in the troposphere.
A mass of hotter-than-normal mantle material that ascends toward the surface, where it may lead to igneous activity. These plumes of solid yet mobile material may originate as deep as the core–mantle boundary.
Many meteors appearing in the sky caused when Earth intercepts a swarm of meteoritic particles.
Lowest tidal range, occurring near the times of the first- and third-quarter phases of the Moon.
An unconformity in which older metamorphic or intrusive igneous rocks are overlain by younger sedimentary strata.
The process by which the portion of a wave in shallow water slows, causing the wave to bend and tend to align itself with the underwater contours.
Soil developed directly from the weathering of the bedrock below.
The rapid slide of a mass of rock downslope along planes of weakness.
A very large star of high luminosity.
The uppermost layer in a soil profile: the A horizon.
The increase in temperature with depth. It averages 1° C per 30 meters (1–2° F per 100 feet) in the crust.
