Question
Oceans:
• What gives seawater its properties
• what are the Areas of the ocean floor
• Active vs. passive shorelines
• Emergent vs. Submergent shorelines
• Major ocean basins?
• Processes that modify affect (other than tectonics) - waves, tides, etc.
• The generation and movement of ocean currents
• Tidal patterns – diurnal, semidiurnal, mixed (what causes tides)
• Parts of a wave, why do waves break, what causes waves
Surface Water and Groundwater: How mass wasting occurs Suspended vs. bed load and hydraulic sorting Stream evolution - where erosion vs. deposition occurs How groundwater moves How groundwater makes caverns and sinkholes Oceans: What gives seawater its properties - salinity, temperature and density . Areas of the ocean floor Active vs. passive shorelines Emergent vs. Submergent shorelines Sources of sediment Major ocean basins Processes that modify affect (other than tectonics) waves, tides, etc. The generation and movement of ocean currents Tidal patterns - diurnal, semidiurnal, mixed (what causes tides) Parts of a wave, why do waves break, what causes wavesExplanation / Answer
1.The presence of salts influences most physical properties of sea water (density, compressibility, freezing point) to some degree but does not determine them. Some properties (viscosity, light absorbtion) are not significantly affected by salinity. The polar nature of water leads to formation of polymer like chains which leads to determination of its properties.
2.abyssal zone,benthic zone,hadal zone are various areas of acean floor
3.An active continental margin is found on the leading edge of the continent where it is crashing into an oceanic plate.Passive continental margins are found along the remaining coastlines. Because there is no collision or subduction taking place, tectonic activity is minimal and the earth's weathering and erosional processes are winning
4.Submergent coastlines are stretches along the coast that have been inundated by the sea by a relative rise in sea levels from either isostacy or eustacy.An emergent coastline is a stretch along the coast that has been exposed by the sea by a relative fall in sea levels by either isostasy or eustasy.
5. there are 5 major ocean basins
Indian ocean basin
southern ocean basin
Arctic ocean basin
Atlantic ocean basin
Pacific ocean basin
6. exogenic process
7.An ocean current is a seasonal directed movement of sea water generated by forces acting upon this mean flow, such as wind, the Coriolis effect, breaking waves, cabbing, temperature.Ocean currents flow for great distances, and together, create the global conveyor belt
8. When the two highs and the two lows are about the same height, the pattern is called a semi-daily or semidiurnal tide. If the high and low tides differ in height, the pattern is called a mixed semidiurnal tide.Some areas, such as the Gulf of Mexico, have only one high and one low tide each day. This is called a diurnal tide.
Gravity is one major force that creates tides
9. parts of wave
Picture of a Wave.
Crest and Trough.
Amplitude.
Wavelength.
Frequency
waves break when their amplitude reaches a critical level that causes large amounts of wave energy to be transformed into turbulent kinetic energy.
Waves located on the ocean's surface are commonly caused by wind transferring its energy to the water, and big waves, or swells, can travel over long distances
