sea level rise
What is water (or H2O)?
This common liquid expands when it freezes, but in the ocean, it expands when it warms up, causing sea levels to rise.
This common gas makes up most of the air; lightning "breaks" it so plants can use it as food.
What is nitrogen?
Oysters build their hard outer shells using this white, chalky mineral also found in Tums and eggshells.
What is calcium carbonate?
Adding this to water increases its density, which is why objects float more easily in the ocean than in a pool.
What is salt?
Lightning is a form of this, the same thing that powers your phone, but in a much more violent "static" form.
What is electricity?
To build shells, oysters pull "carbonate ions" from the water; as the ocean becomes more acidic, these ions become much harder to this "S-word" verb.
What is sequestration?
This gas, released by burning fossil fuels, is absorbed by the ocean and is a primary driver of global warming.
What is carbon dioxide?
A lightning bolt is five times hotter than the surface of this, our closest star.
What is the sun?
Because they filter up to 50 gallons of water a day, oysters are known as "nature's" these, a term for a device that removes impurities.
What are filters?
This term refers to the "mixture" created when salt is dissolved in water; when it warms, the molecules move apart, causing the sea level to rise.
What is a solution?
Most lightning stays inside these "fluffy" water-vapor collections before ever hitting the ground.
What are clouds?
On the pH scale, oysters prefer water that is slightly "basic," which is the opposite of this 6-letter term.
What is acidic?
When water changes from a solid (ice) to a liquid, it undergoes this two-word "change" that is currently happening to the polar ice caps.
What is a phase change?
This "scent-sational" gas is created when lightning strikes; it protects the Earth from UV rays in the upper atmosphere.
What is ozone?
This gas, when dissolved in seawater, reacts to form carbonic acid, which can actually dissolve a baby oyster's shell.
What is carbon dioxide?
