A subdivision of the benthic zone characterized by extremely high pressures, low temperatures, low oxygen, few nutrients, and no sunlight.
An unconformity in which the strata below dip at an angle different from that of the beds above.
The region in which most asteroids orbit the Sun between Mars and Jupiter.
The depression at the summit of a volcano, or that which is produced by a meteorite impact.
The distance from the lens to the point where it focuses parallel rays of light.
Any break or rupture in rock along which no appreciable movement has taken place.
The boundary between two adjoining air masses having contrasting characteristics.
The southern portion of Pangaea consisting of South America, Africa, Australia, India, and Antarctica.
Hot spot track
Chain of volcanic structures produced as a lithospheric plate moves over a mantle plume.
Depressions created when blocks of ice became lodged in glacial deposits and subsequently melted.
A span on the geologic time scale between the Paleozoic and Cenozoic eras from about 248 million to 65 million years ago.
All discovered and undiscovered deposits of a useful mineral that can be extracted now or at some time in the future.
The source of the Sun’s energy.
The process by which plants and algae produce carbohydrates from carbon dioxide and water in the presence of chlorophyll, using light energy and releasing oxygen.
Deposit formed when heavy minerals are mechanically concentrated by currents, most commonly streams and waves. Placers are sources of gold, tin, platinum, diamonds, and other valuable minerals.
A strong narrow surface or nearsurface current of short duration and high speed flowing seaward through the breaker zone at nearly right angles to the shore. It represents the return to the ocean of water that has been piled up on the shore by incoming waves.
A local wind blowing from the sea during the afternoon in coastal areas.
Tropic of Cancer
The parallel of latitude, 231?2 degrees north latitude, marking the northern limit of the Sun’s vertical rays.
The concept that the processes that have shaped Earth in the geologic past are essentially the same as those operating today
Gaseous components of magma dissolved in the melt. Volatiles will readily vaporize (form a gas) at surface pressures.
