Unique Nature of Pure Water
It has two atoms of hydrogen and one atom of oxygen chemically bonded together.
What elements make up water?
It allows for photosynthesis underwater.
Why is seawater’s transparency important?
It is the total amount of salt dissolved in the water.
What is salinity?
This is where the carbon that forms the backbone of all organic molecules comes from.
What is the atmosphere?
This zone is 0-200m deep in the ocean.
What is the epipelagic zone?
Hydrogen bonding
What is the attraction of one water molecule to another?
It increases by 1 every 10 meters deeper underwater.
What happens to pressure as you go deeper underwater?
Why does seawater taste like table salt?
Rising CO2 levels affect this aspect of the ocean.
What is the chemistry of the ocean?
This zone is 200m-1000m deep in the ocean.
What is the mesopelagic zone?
Ice is less dense than liquid water
Why does ice float on water?
It travels 4.5 times faster underwater.
How does seawater affect sound?
The result of the addition or removal of pure water.
What causes variations in ocean salinity?
This is used to describe the pH of the ocean dropping and it become less alkaline.
What is ocean acidification?
This zone is 1000m-4000m deep in the ocean.
What is the bathypelagic zone?
What happens to water when it freezes?
It is the reason why blue light travels the farthest underwater.
How does seawater affect light penetration?
Temperature in the ocean varies considerably more than salinity.
Why is density controlled more by temperature than salinity?
These ions are harder for shelled organisms to obtain because of ocean acidification.
What are carbonate ions?
This zone is 4000m-6000m deep in the ocean.
What is the abyssopelagic zone?
The slightly charged ends of water molecules
What causes water to be polar?
It decreases the further underwater you go.
What is the temperature of water?
These elements, such as metals or metalloids, are present in tiny amounts in the ocean.
What are trace elements?
This can cause greater death rates in marine organisms.
What do greater CO2 concentrations in the ocean lead to?
This zone is 6000m-11000m deep in the ocean.
What is the hadalpelagic zone?
