Unique Nature of Pure Water
What is the chemical formula for water?
What is H₂O?
The amount of dissolved salts in seawater.
What is salinity?
The most abundant dissolved salt in seawater.
What is Sodium Chloride?
The gas absorbed by the ocean that contributes to ocean acidification.
What is Carbon Dioxide
The ocean zone that receives the most sunlight and supports most photosynthesis.
What is the epipelagic zone?
What type of bond holds the hydrogen and oxygen atoms together within a water molecule?
What is a covalent bond?
The 2 main factors that dictate seawater density.
What is tempurature and salinity?
The most abundant positively charged ion in seawater.
What is Sodium?
The natural process through which carbon moves among the atmosphere, ocean, land, and living organisms.
What is the carbon cycle?
The ocean zone known as the twilight zone, where sunlight decreases significantly.
What is the mesopelagic zone?
What weak attraction forms between neighboring water molecules?
What are hydrogen bonds?
What happens to seawater density when salinity increases and temperature stays constant.
What is an increase in density?
The most abundant negativity charged ion in seawater.
What is chloride?
The weak acid formed when carbon dioxide reacts with seawater.
What is carbonic acid?
The ocean zone where sunlight no longer reaches and the water is very cold.
What is the bathypelagic zone?
What property allows water to absorb large amounts of heat before its temperature rises significantly?
What is high specific heat?
The reason seawater freezes at a lower temperature than pure water.
What is the effect of dissolved salts lowering the freezing point.
The principle stating that the major dissolved ions in seawater maintain nearly constant proportions.
What is the principle of constant proportions?
The reason seawater pH decreases when extra carbon dioxide dissolves in the ocean.
What is an increase in hydrogen ion concentration?
The ocean zone that extends from about 6,000 meters to the ocean floor in the deepest trenches.
What is the hadalpelagic zone?
Why does ice float on liquid water, allowing aquatic life to survive beneath frozen surfaces?
Because ice is less dense than liquid water.
The sample of seawater that is denser when two samples have equal salinity but different temperatures.
What is the colder sample?
The process that increases seawater salinity while leaving most dissolved salts behind.
What is evaporation?
The ions that become less available as ocean acidification makes it harder for corals and shell-building organisms to form calcium carbonate.
What are carbonate ions?
The ocean zone between approximately 1,000 and 4,000 meters deep, known for complete darkness and high pressure.
What is the bathypelagic zone?
