Study Notes
Salinity with Latitude
- Salinity decreases with precipitation.
- Salinity increases with evaporation.
Ocean Water Temperature
- Ocean water temperature varies with depth.
Ocean Water Density
- Ocean water density varies with depth.
Ocean Layering
- Ocean layering based on density with depth.
- Ocean layering is different at high latitudes.
Marine Life
- Marine life varies based on the amount of light.
- Marine life varies based on distance from shore.
- Marine life varies based on water depth.
Surface Currents
- Surface currents are driven by wind transferring energy to water by friction.
Major Surface-Ocean Currents
- Major surface currents are driven by wind.
Thermohaline Circulation
- Thermohaline circulation is driven by density differences caused by temperature and salinity differences in the ocean.
Wave Basics
- Waves are caused by wind.
Waves Approaching Shore
- Waves slow down as they approach the shore.
- Waves bend as they approach the shore, due to friction caused by the ocean floor.
Shoreline Processes
- Wave refraction occurs when waves bend as they approach the shore.
- Longshore transport is a process where sediment is moved along the shore by waves.
Tides
- Tides are caused by the gravitational force of the moon and sun.
- High tide, low tide and tidal ranges are all caused by the gravitational force of the moon and sun.
- Spring tides occur when the sun, moon, and Earth are aligned. This causes a larger tidal range.
- Neap tides occur when the sun, moon, and Earth are at right angles. This causes a smaller tidal range.
