The smallest particle that exists as an element.
A sandbar that completely crosses a bay, sealing it off from the open ocean.
Chemical sedimentary rock
Sedimentary rock consisting of material that was precipitated from water by either inorganic or organic means.
Structure in which relatively thin layers are inclined at an angle to the main bedding. Formed by currents of wind or water.
Lifting of air resulting when cool air acts as a barrier over which warmer, lighter air will rise.
The 2,900-kilometer- (1,800-mile-) thick layer of Earth located below the crust.
See Oceanic ridge system.
A term often used synonymously with hypothesis but is less precise because it is sometimes used to describe a theory as well.
The marine-life zone that extends from the low tideline out to the shelf break.
Warm air gliding up a retreating cold air mass.
A very coarse-grained igneous rock (typically granite) commonly found as a dike associated with a large mass of plutonic rock that has smaller crystals. Crystallization in a waterrich environment is believed to be responsible for the very large crystals.
A measure of a material’s ability to transmit water.
The upper part of the ocean into which any sunlight penetrates.
A consolidated mixture of minerals.
A solid form of precipitation produced by sublimination of water vapor.
A flattened, rotating galaxy with pinwheel-like arms of interstellar material and young stars winding out from its nucleus.
In any undeformed sequence of sedimentary rocks, each bed is older than the layers above and younger than the layers below.
The study of the large-scale processes that collectively deform Earth’s crust.
Soils that form on unconsolidated deposits.
A pyroclastic rock composed of particles that have been fused together by the combination of heat still contained in the deposit after it has come to rest and by the weight of overlying material.
