A continuous or broken ring of coral reef surrounding a central lagoon.
Banded iron formations
A finely layered iron and silica-rich (chert) layer deposited mainly during the Precambrian.
A low, elongate ridge of sand that parallels the coast.
The level below which a stream cannot erode.
The measurement of ocean depths and the charting of the shape or topography of the ocean floor.
Zone of inclined seismic activity that extends from a trench downward into the asthenosphere.
Mineral group whose members contain the carbonate ion and one or more kinds of positive ions. Calcite is a common example.
A star whose brightness varies periodically because it expands and contracts. A type of pulsating star.
A type of volcanism that results from the eruption of magmas derived from the partial melting of ice.
Geologic time scale
The division of Earth history into blocks of time—eons, eras, periods, and epochs. The time scale was created using relative dating principles.
A concentration of heat in the mantle capable of producing magma, which in turn extrudes onto Earth’s surface. The intraplate volcanism that produced the Hawaiian Islands is one example.
A change in Earth’s magnetic field from normal to reverse or vice versa.
A wave-cut platform that has been exposed above sea level.
A layer beneath the mantle about 2,200 kilometers (1,364 miles) thick that has the properties of a liquid.
A basic unit of the geologic calendar that is a subdivision of an era. Periods may be divided into smaller units called epochs.
The point where a rapid steepening of the gradient occurs, marking the outer edge of the continental shelf and the beginning of the continental slope.
A flattened, rotating galaxy with pinwheel-like arms of interstellar material and young stars winding out from its nucleus.
The force per unit area acting on any surface within a solid.
A layer in the atmosphere of limited depth where the temperature increases rather than decreases with height.
The state of the atmosphere at any given time.
