Unique Nature Of Pure Water
Two elements that make up a water molecule
What is Hydrogen and Oxygen.
The instrument used to measure water clarity
What is Secchi disk?
The total amount of salt dissolved in water
What is Salinity?
The gas from the atmosphere that dissolves into the ocean and enters the carbon cycle
What is Carbon dioxide?
The name of the oceans sunlight zone
What is Epipelagic Zone?
The attraction between water molecules
What is Hydrogen bonding?
The color of light that penetrates deepest into the ocean.
What is Blue?
The average salinity of the ocean
What is about 35 parts per thousand(35% or 3.5%)
The procces that converts carbon dioxide into organic compounds
What is photosynthesis?
The ocean layer that extends from 200 to 1,000 meters
What is the Mesopelagic zone ( twilight zone)?
This property allows water to resist rapid temperature changes
What is High Heat Capacity?
The approximate amount of times faster sound travels through water than through air
What is 4.5 times faster?
Two ions that make up about 85% of the ions in seawater
What is Sodium and Chloride?
The result of ocean pH as ocean acidification increases
What is the pH decreases, making the ocean less alkaline?
the ocean layer that extends from 4,000 meters
What is the Bathypelagic zone ( Midnight zone)?
The name for water molecules sticking to other water molecules
What is Cohesion?
The amount of additional pressure added for every 10 meters of ocean depth
What is one atmosphere?
The affect of density of seawater when salinity is increased
What is density increases.
The type of marine organisms that is especially at risk from ocean acidification because it needs calcium carbonate
What is organisms that build shells or skeletons, such as oysters or crab
Compare the Hadalpelagic Zone with the Epipelagic zone in depth, light, and temperature
What is The Hadalpelagic Zone extends from 6,000 to 11,000 meters and is extremely dark and very cold. The Epipelagic Zone extends from 0 to 200 meters, receives the most sunlight, and has warmer water.
The reason aquatic organisms survive in water beneath a frozen lake’s surface
What is that ice is less dense than liquid water , so it floats and insulates the water below it.
The affect of pressure and gases when ocean depth is increased
What is pressure increases, causing gases to become compressed?
The main reason ocean salinity changes near a river mouth
What is the addition of freshwater changes the concentration of dissolved salts?
Explain how increasing carbon dioxide can affect marine food webs
What is ocean acidification makes it harder for orga to build shells and skeletons, affecting species throughout the food chain.
The ocean layer that extends from 4,000 to 6,000 meters
What is the Abyssal Zone ( lower midnight zone)
