unique nature of pure water s.1
the 2 elements that make up a water molecule.
what is hydrogen and oxygen?
this measures how hot or cold seawater is.
what is temperature?
the concentration of dissolved salt in seawater.
what is salinity?
the ocean absorbs this carbon containing gas from the atmosphere.
what is carbon dioxide?
this ocean from 0-200 meters is called the sunlight zone.
what is the epipelagic zone?
a water molecule has slightly positive and negative ends which make it this type of molecule.
what is a polar molecule?
this force increases as an organism travels deeper into the ocean.
what is pressure?
these 2 ions are the most abundant dissolved ions in seawater.
what is sodium and chloride?
this process converts carbon dioxide into glucose.
what is photosynthesis?
this layer extends from 200-1000 meters and is callled the twilight zone.
what is the mesopelagic zone?
this type of attraction is formed when the hydrogen of one water molecule and the oxygen of another combine.
what is a hydrogen bond?
if 2 seawater samples have the same temperature, the saltier sample usually contains more of this property.
what is density?
seawater averages this salinity.
what is 35 parts per thousand?
respiration by these 3 groups returns carbon dioxide to the environment.
what are producers, consumers, and decomposers?
an animal at 2500 meters makes its own light. name the ocean layer and what the light making process is.
what is the bathypelagic zone and bioluminescence?
this property is what allows for water molecules to stick together.
what is cohesion?
this ocean layer has rapid decreases in temperature as depth increases.
what is the thermocline?
explain why evaporation increases salinity of water left behind.
what is water evaporating while dissolved salts remain which increases the concentration?
explain how the ocean can experience acidification while its ph remains at 7.
what is acidification means a decrease in ph so seawater becomes less alkaline without it becoming acidic?
identify the ocean layers containing depth of 5000 meters and 8000 meters.
what is the abyssopelagic and hadalpelagic zones?
ice floats on water because of this.
what is hydrogen bonds holding water molecules far apart in ice?
a cold, salty water amount meets a warmer, less salty water amount. this temperature water amount sinks.
what is cold, salty water sinking because it is denser and warmer water rising because it is less dense?
explain why seawater generally freezes at a lower temperature than pure water.
what is dissolved salt interfereing with ice formation and lowering the freezing point?
explain the chain of events connection increased carbon dioxide in the atmosphere to difficulty building shells.
what is more carbon dioxide dissolving in seawater which forms carbonic acid and reduces available carbonate ions which are needed to build calcium carbonate shells?
why can photosynthesis not support producers in the midnight zone and identify 2 ways food can reach animals.
what is not enough sunlight preventing photosynthesis with animals receiving food through sinking organic matter and reaching other organisms?
