Nature of water
What type of bond holds water molecules together?
What is a hydrogen bond
what 2 main factors affect the density of seawater
what is temperature and salinity
what is the average salinity of sea water
what is 35 parts per thousand
what gas is responsible for ocean acidification
what is carbon dioxide
What process do plants and phytoplankton use
what is photosynthesis
Why is water called a polar molecule
what is because hydrogen is positive and oxygen is negative
What instrument is used to measure salinity
what is a salinometer
What is the 2 most abundant ions in seawater
what is sodium and chloride
What happens to ocean PH as more c02 disolves in sea water
what is the PH decreasing
What process releases c02 back into the atmosphere
what is respiration
What property allows water to stick to itself
what is cohesion
How does temperature affect the density of seawater
what is cold water is denser then warm water
What process adds salt to the ocean
what is weathering and erosion
How does ocean acidification affect shell-building organisms
what is it reduces the amount of carbonate ions needed to build shells and skeletons
What is the term for waters ability to resist temperature change
what is high specific heat capacity
What causes layers in the ocean
what is differences in temperature and salinity
What principal states that the relative proportions of major ions in seawater remain constant
what is the principal of constant proportions
What compound forms when c02 reacts with water
what is carbonic acid
how does the ocean act as a carbon sink
what is it absorbs c02 from the atmosphere
Why is water less dense as a solid than as a liquid
what is because hydrogen bonds form a crystalline structure that spaces water molecules farther apart when frozen.
What is the term for the rapid change in temperature with depth in the ocean
what is the thermocline
What is the universal solvent
what is water
Why is ocean acidification considered a threat to the food web
what is it affects producers which affects everything
What is the biological pump in the ocean carbon cycle
what is the process of how carbon is transferred from the carafe to the deep
