Unique Nature of Pure Water
The result of two or more atoms bounded chemically.
What are molecules?
The effects on pressure that ocean depth has.
What is decreases?
One chemical property salt water has that pure water doesnt.
The element that circles around in a cycle from the atmosphere to the ocean and is the backbone of all organic molecules.
The amount of layers of the ocean.
In one water molecule there are these many atoms of hydrogen and these many atoms of oxygen.
What are 2 atoms of hydrogen and one atom of oxygen?
The color that withstands the decrease in depth the most.
What is blue?
The two most common ions in salt water.
What are sodium and chloride?
The process the turns carbons dioxide into organic compounds.
What is photosynthesis?
The order of the 5 layers of the ocean, from surface to bottom.
What is epipelagic zone, mesopelagic zone, bathypelagic zone, abyssopelagic zone, hadalpelagic zone
The measure of the elastic tendency of fluids.
What is surface tension?
The name of the tool that helps scientists measure water clarity.
What is a secchi disk?
The average salinity of the ocean.
What is 35%?
The process where the ocean pH is dropping and it becomes less alkaline.
What is ocean acidification.
The two zones that do recieve at least some sunlight.
What are epipelagic and mesopelagic zone?
When salt dissolves in water this happens.
What is the ions in salt dissociate?
If an organism is under 20m of water depth, they are under this many atmospheres of pressure.
The effect of saltier water.
What is more dense water?
The average pH of the ocean.
What is 8.0-8.3?
The process of animals migrating up to the surface at night to eat and back down in the day to hide is called.
What is vertical migration?
The unique effect of water when it freezes
What is the water expands and becomes less dense?
Sound in water travels this many times faste than in air.
What is 4.5 times faster.
The element that is usually metals/metalloids and are present in tiny amounts in the ocean.
What is trace elements?
Some effects of great CO2 concentrations.
What are:
- greater mortality rates in marine larvae
- harms the immune system of many animals
- can alter the behavior of organisms- can affect any animals that use sound because it makes sound waves travel much further.
The zone where rat-tail fish live
what is the hadalpelagic zone?
