Unique Nature of Pure Water
This type of bond holds water molecules together, giving water its high surface tension.
What is a Hydrogen bond?
The salty taste of sea water is primarily due to this ion.
What is Salt?
The pH of typical seawater is slightly below, at, or above this value?
What is seven ph?
This gas is the main cause of ocean acidification.
What is carbon?
This process converts atmospheric CO₂ into organic molecules in plants and algae.
What is carbon fixation?
Water’s ability to absorb a large amount of heat without a significant temperature change is called this.
What is specific heat?
The average salinity of ocean water is about this number of parts per thousand
35 parts per thousand
Seawater’s alkalinity is mainly due to the presence of these ions
What is bicarbonate?
When CO₂ dissolves in water, it forms this weak acid.
What is carbonic acid?
Oceans act as a carbon sink by absorbing this form of carbon from the atmosphere.
What is CO2?
The unusual property of water that allows ice to float is due to this
What is water reduced density as a soli?
Sea water is denser than fresh water because it contains these.
What is dissolved minerals?
The process by which carbon dioxide reacts with seawater to form carbonic acid is called this
What is ocean acidification?
Ocean acidification primarily reduces the availability of this carbonate-based compound necessary for marine organisms to build shells.
What is calcium carbonate?
Water can dissolve many substances, earning it this nickname
What is The Universal Solvent?
The temperature and salinity of seawater influence this property, which affects ocean currents
What is Density?
Magnesium and sulfate ions in seawater can combine to form this common mineral.
What is Epsomite?
Acidification can impact marine life by affecting the structure of these microscopic organisms used in the food chain.
What is mollusks?
This long-term geological process stores carbon in sedimentary rock for millions of years.
What is the slow carbon cycle?
The property that allows sea water to conduct electricity is due to the presence of this.
What is dissolved salt?
This chemical equilibrium involving CO₂, HCO₃⁻, and CO₃²⁻ buffers seawater but is disturbed by increasing atmospheric CO₂.
What is the carbonate system?
The slow movement of carbon between rocks, oceans, and the atmosphere over millions of years is called this cycle.
What is the geological carbon cycle?
