Section 3.2, Physical and Chemical Properties of Seawater Main Idea: The ocean and the atmosphere interact leading to heat being transported from one area to another around Earth. What Makes Seawater Different Than Pure Water? Seawater is a mixture of pure water and ____________________ dissolved into it from the ____________________________ and other sources of _______________________. Sources of runoff: ________________________ of rocks on land Materials from the interior of the earth released through _________________________ and _____________ in the rift valley of the ____________________________________. Materials released into the atmosphere from ___________________ and then placed in the ocean via ________________________. Physical Properties of Seawater: TransparencyD The ability of light to _____________________ a substance. PressureD The amount of ______________ applied per unit _________________________. Sound PropagationD The changing of ___________________ in different areas of seawater. Transparency of Seawater: One of the most __________________________________________________ of seawater. Sunlight must be able to penetrate seawater so __________________________ organisms (Organisms that produce energy through ____________________________) can grow. Different colors of light reach different depths of the ocean. ________ penetrates the most. Light does not penetrate more than _______________ m deep. Water transparency at different depths is measured with a _________________________

Pressure of Seawater: The pressure at sea level is ___ atm (atmosphere). This is the weight of all of the air above them per unit area (___________ pounds per square inch). Marine organisms also have to accommodate the pressure of the ____________________ AND the ______________________________. Water is much heavier than air so marine organisms have to be able to withstand more pressure than land organisms. The pressure of water drastically increases with the depth. Pressure increases approximately 1 atm every _______ m of depth. Sound Propagation in Seawater: Since water is denser than air, sound travels ___________ times faster in water than air (__________ m/s in air, ________________ m/s in the shallow ocean). The speed of sound in water varies as a function of _______________________________. The __________ salinity, temperature, and pressure cause sound to travel _____________. The depth at which sound travels slowest varies with ________________. This region is known as the ______________________________________________. This region is important for ________________ and _____________________________ because sound waves can travel ___________________________________. Because light and sight are limited in water, sound and hearing are the most important sense for marine organisms. Chemical Properties of Seawater: SalinityD The amount of __________________ dissolved in water DensityD The amount of ___________________ per unit ________________ of a substance.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
