salinity

• a measure of the amount of dissolved salts in a given amount of liquid

• a layer in a body of water in which water temperature drops with increased depth faster than it does in other layers

• the shallow seafloor that is located between the shoreline and the deep-ocean bottom

mid-ocean ridge

• a measure of the amount of dissolved salts in a given amount of liquid

• a layer in a body of water in which water temperature drops with increased depth faster than it does in other layers

• a long, undersea mountain chain that forms along the floor of the major oceans
