Unique Nature of Pure Water
2 elements that make up a water molecule
What are Hydrogen and Oxygen?
The average salinity of ocean water, measured in parts per thousand
What is 35ppt?
The two most abundant ions in the seawater
What are sodium and chloride?
The gas absorbed by oceans that contributes to acidification
What is carbon dioxide?
The sunlit upper layer of the ocean
What is the epipelagic zone?
Type of bond that holds neighboring water molecules
What is hydrogen bonds?
The amount of salt dissolved in water
What is salinity?
The chemical formula for water
What is H2O?
The process by which oceans absorb carbon dioxide from the atmosphere
What is carbon sequestration?
The ocean layer where sunlight decreases rapidly
What is the mesopelagic zone?
Property of water that allows it to absorb large amounts of heat without changing temperature very quickly
What is high specific heat capacity?
the process in which saltwater becomes denser as it cools
What is an increase in density due to cooling?
The measure of how acidic or basic seawater is
What is pH?
The substance formed when carbon dioxide reacts with seawater that lowers ocean pH
What is carbonic acid?
The zone where sunlight does not reach
What is the abyssopelagic zone
what is, ice is less dense than liquid water because hydrogen bonds form an open crystal structure when water freezes?
The physical property that causes light to decrease as it travels deeper into the ocean
What is light absorption?
The dissolved gas that fish need to survive
What is oxygen?
The effect of ocean acidification on corals and shell building animals
What is difficulty building and maintaining shells and skeletons?
The deepest part of the ocean, including ocean trenches
What is the hadalpelagic zone?
These bonds explain why water heats up and cools down slowly, helping regulate Earths climate
What are hydrogen bonds?
The movement caused by differences in water temperature and density
What are convection currents?
The process in which dissolved substances separate into charged particles in water
What is ionization?
The name for the movement of carbon among the atmosphere, ocean, land, and living things
What is the carbon cycle?
When creatures go up to the surface from the mesopelagic zone at night to get food
What is DVM
