Plate boundaries that generate continental volcanic arcs.
A hard, metamorphic form of coal that burns clean and hot.
Seismic waves that travel through Earth’s interior.
Circle of illumination
The great circle that separates daylight from darkness.
The fuzzy, gaseous component of a comet’s head.
A belt of low pressure lying near the equator and between the subtropical highs.
A cliff created by movement along a fault. It represents the exposed surface of the fault prior to modification by weathering and erosion.
A mountain formed by the displacement of rock along a fault.
A succession of organisms in an ecological community through which food energy is transferred from producers through herbivores and on to one or more carnivores.
The slope of a stream; generally measured in feet per mile.
An elongated, uplifted block of crust bounded by faults.
Law of conservation of angular momentum
The product of the velocity of an object around a center of rotation (axis), and the distance squared of the object from the axis is constant.
Igneous rocks with a low silica content and a high iron–magnesium content.
The zone of beach that extends from the low-tide shoreline seaward to where waves break at low tide.
The eon following the Archean and preceding the Phanerozoic. It extends between about 2,500 million (2.5 billion) and 540 million years ago.
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.
The motion of one body about another, as Earth about the Sun.
The fine sediment carried within the body of flowing water.
Temporary (local) base level
The level of a lake, resistant rock layer, or any other base level that stands above sea level.
A storm produced by a cumulonimbus cloud and always accompanied by lightning and thunder. It is of relatively short duration and usually accompanied by strong wind gusts, heavy rain, and sometimes hail.
