|
mpome
|
|
oolits
|
a deposit formed of small spheres usually composed of concentric layers of calcite
|
|
|
relict sediment
|
a sediment deposited under a set of environmental conditions that still remains unchanged.
|
|
|
stromatolites
|
a dome shaped calcium carbonate sedimentary structure
|
|
|
turbidites
|
a sediment ofrock formed by sediment deposited by turbidity currents
|
|
|
graded bedding
|
stratification in which each layer displays a decrease in grain size from bottom to top.
|
|
|
calorie
|
unit of energy required to raise the temp of 1 g of water 1 degree
|
|
|
heat capacity
|
the amount of heat required to raise the temperature of 1 gram of a substance 1 degree
|
|
|
residence Time
|
the average length of time a particle of any substance spends in the ocean.
|
|
|
viscosity
|
internal friction
|
|
|
latent heat of melting and vaporization
|
latent heat of melting is the heat enegy that must be added to 1 gram of a substance at its melting point to convert to a liquid. Latent heat of vaporization is added at its boiling point to convert it to vapor. 80 degrees and 540 degrees
|
|
|
Surface tension
|
tendency for the surface of a liquid to contract due to intermolecular bond attraction
|
|
|
adhesion
|
water that clings to surfaces of many substances
|
|
|
cohesion
|
water molecules that cling together.
|
|
|
Hadley cells
|
0-30 degs lat the large atmospheric circulation cell that occurs between the Equator and 30 deg lat in each hemisphere
|
|
|
Ferrell Cells
|
30-60 deg lat The atmospheric circulation pattern within the lower atmosphere between the subtropical high-pressure belt and the relatively low-pressure belt at the polar front.
|
|
|
Polar cells
|
60-90 degrees lat
|
|
|
doldrums
|
a belt of light variable winds within 10 degrees to 15 degrees of the Equator, resulting from the vertical flow of low-density air withing this equatorial belt
|
|
|
Horse latitudes
|
the latitudes belts between 30 and 35 degrees North and South latitude where winds are light and variable . The climate is hot and dry resulting in the creation of the major continental and maritime desert of the world.
|
|
|
Intertropical Convergence Zone
|
Where Northeast trade winds converge with southeast trade winds.
|
|
|
gyres
|
a circular flow created by the equatorial, western boundary, eastern boundary and prevailing westerly currents. They move clockwise in the northern hemisphere and counter clockwise in the southern hemisphere.
|
|
|
Kyoto Protocol
|
An agreement among 60 nations to voluntarily reduce greenhouse gas emissions.
|
|
|
cosmosgenous sediments
|
sediment derived from extraterrestrial sources like microscopic spherules and macroscopic meteor space dust.
