Cards in this deck (35)
- 1OceanographyIs the branch of science concerned with the physical and biological properties and phenomenon of the ocean
- 2The Five Oceans Are;Pacific, Atlantic, Arctic, Indian and Southern
- 3The Big Bang13.7 billion years ago, the believed markings of the universe
- 4Galaxya rotating collection of stars, dust, gas and other debris held together by gravitational force
- 5Condensation TheoryThe theory to describe the formation of stars. A stars life begins when the nebula shrinks and heats up under its own gravitational forces and flattens creating a proto star
- 6Red GiantWhen the star consumes H and O atoms and its body starts to swell
- 7SupernovaWhen no more compression of a star can happen and a massive explosive expansion occurs.
- 8AccretionThe process that a planet forms , small particles clump together with bigger particles.
- 9PangeaWhen the world was one super continent
- 10Covalent BondA chemical bond when electrons are shared between atoms
- 11Polar MoleculeThe molecule has a positive and a negative end
- 12CohesionThe ability of individual water molecules to stick together
- 13AdhesionThe tendency for water molecules to stick to other materials (h bonding)
- 14Temperaturean objects response to input or removal of heat
- 15Heatthe energy produced by the random vibration of atoms or molecules
- 16Surface/ mixed zonethe upper layer of the ocean, temperature and salinity remain constant
- 17Pycnoclinezone where density increases with increasing depth
- 18Deep ZoneTypically lies at depths >1,000 m very little change in water density
- 19Haloclinea zone of rapid salinity increase with depth
- 20Photic Zonethe zone that light penetrates through
- 21Aphotic Zonethis zone is perpetual darkness
- 22Solutiona solution is made up of two components a solvent (usually a liquid with more abundant constitutions) and a solute (less abundant dissolved solid or gas)
- 23Diffusionthe random movement of materials through a solution, usually from areas of higher concentrations of materials to areas of lower concentrations
- 24SalinityThe measure of the total quantity or concentration of dissolved inorganic solids in water
- 25Residence TimeDescribes the average length of time that an ion or element may spend in the ocean
- 26Acidis a substance that releases a hydrogen ion in a solution
- 27BaseA substance that combines with a hydrogen ion in a solution
- 28pH sclaemeasures the concentration of hydrogen ions in a solution. An excess of H ions makes the solutions acidic well an excess of hydrogen ions makes the solution basic.
- 29Alkalinea solution that is basic
- 30Climateis the long term statistical view of weather in an area
- 31Weatheris the state of the atmosphere a specific time and place e
- 32Heat Budgetthe input and output of energy from the earth
- 33Convection CurrentsThe circular current of air that is moving in the room
- 34Atmospheric Circulation Cellwhen air mass travels between the equator and the pole, there are 6 cells: hadley cells, ferrel cells, and polar cells (2 of each)
