Unique Nature of Pure Water (Section 1)
What type of bond holds water molecules together?
What is hydrogen bond?
What is the average salinity of seawater?
What is 35 ppt?
What is the normal pH of seawater?
What is around 8.1?
What causes ocean acidification?
What is increased carbon dioxide dissolving in seawater?
What process removes carbon dioxide from the air?
What is photsynthesis?
What property allows water to stick to other surfaces?
What is adhesion?
What two ions make up most of the salt in seawater?
What is sodium and chloride?
What gas is most important for marine photosynthesis?
What is carbon dioxid?
When carbon dioxide dissolves in seawater, what acid forms?
What is carbonic acid?
What process adds carbon dioxide to the atmosphere?
What is respiration or combustion?
Why does ice float on liquid water?
What is because ice is less dense than liquid water?
How does temperature affect the density of seawater?
What is colder water is denser than warmer water?
What gas do marine animals release through respiration?
What is carbon dioxide?
What happens to the pH of seawater as acidification increases?
What is the pH decreases (becomes more acidic)?
What form of carbon is stored in shells and limestone?
What is calcium carbonat?
What is the term for water’s ability to resist changes in temperature?
What is high specific heat?
What happens to salinity when seawater evaporates?
What is it increases?
What is the term for the ocean’s ability to resist pH change?
What is buffering capacity?
How does acidification affect shell-building organisms?
What is it weakens or dissolves their calcium carbonate shells?
What role does the ocean play in the carbon cycle?
What is it acts as a carbon sink, absorbing CO₂ from the air?
How does the polarity of water affect its ability to dissolve substances?
What is the polar nature allows water to attract and separate ions, making it a universal solvent?
What physical property causes ocean layering?
What is differences in temperature and salinity (density)?
Why does the ocean have a nearly constant composition of salts?
What is because of the balance between input and removal of materials?
Why is ocean acidification called the “other CO₂ problem”?
What is because it’s caused by the same emissions driving climate change?
How do upwelling and downwelling affect carbon movement?
What is they bring carbon-rich water to the surface and move it to deep ocean layer?
