30% to 40% of the CO2 emitted by humans ends up in the oceans, where it forms carbonic acid. This increases ocean acidity, decreasing the pH, which is in turn harmful to many marine organisms.

What happens to greenhouse gases at natural levels in the atmosphere?
At natural levels of greenhouse gases in the atmosphere (before the Industrial Revolution), the carbon cycle moved carbon dioxide in and out of land, sea and air. Enough carbon dioxide remained in the atmosphere to keep the earth comfortably warm, warm enough for life.
What is the source of carbon dioxide for water plants?
Carbon dioxide in the oceans primarily comes from the atmosphere. Some of the carbon dioxide from the air dissolves into the ocean water. However, smaller amounts can come from respiration of sea animals and other miscellaneous sources. The atmosphere is by far the largest source of carbon dioxide in ocean water, though.
Is there an experiment to show that sea shells contain carbonate?
They are easily dissolved in acids releasing carbon dioxide as a gas.
Is dry ice a chemical?
Dry ice is simply the chemical carbon dioxide in its solid state. Dry ice is very cold and sublimates directly into carbon dioxide gas at negative 78.5 degrees Celsius at sea level.
What are the effects do solutes have on a solvent when at freezing and boiling point?
the colder a liquid, the more gas it will dissolve, the hotter it is the more solid stuff like sugar it will dissolve. the sea is other wise known as the carbon sink because of the amount of carbon dioxide dissolved in it. because of climate change, the sea is getting warmer and carbon dioxide is being relised into the atmospherei hope that helps :)

Does the amount of sunlight affect how much carbon dioxide goes into the ocean?
Carbon dioxide absorption by the oceanis affected by how much is there already and solubility equilibrium.The second first - carbon dioxide dissolves into sea water depending on temperature. Warmer water can hold less. As a consequence sunlight can reduce the absorptive capacity by warming the water.Carbon dioxide enters the water to bring up the carbon dioxide levels to saturation levels. If the level in the water is educed by being absorbed by plants (algae) there is a deficiency of carbon dioxide and more carbon dioxide enters the water to make up the deficiency. Algae is more active when exposed to sunlight and absorbs more carbon dioxide. Sunlight thus enhances that amount of carbon dioxide transferring to the water from the atmosphere.
What is the use of carbon dioxide in the sea?
Any use; body of waters absorb carbon dioxide. Today the absorbed carbon dioxide exeeded the normal limits and the pH of seas/oceans become more and more acidic.
How did carbon dioxide end up in sedimentary rocks?
Carbon dioxide is dissolved into the sea. Marine organisms use the dissolved carbon dioxide to make shells of calcium carbonate. When these organisms die, they fall to the sea bed. Layers of dead organisms and sediment build up on the sea bed. These layers are compacted and compressed to form sedimentry rock.
What is the atmosphere made of on Venus?
It is mostly carbon dioxide, 97 %, at a pressure 90 times that of earth's atmosphere at sea level.
What is the total amount of Carbon Dioxide in the air now?
This highly dependent on location. However the average sea level Carbon Dioxide ( CO2) concentration is 0.0314 % (314 ppm)

How does carbonate get into rocks?
There is carbon dioxide in the sea and animals die and falkl to tyhe sea bed and create carbonate in rocks
How do you extract carbon dioxide from air?
The only way to permanently remove carbon dioxide from the air is by photosynthesis. Photosynthesis removes carbon dioxide and stores it in the trees and vegetation.There are several routes for carbon dioxide removal, In Nature:Plants use carbon dioxide for the process of manufacturing foodCarbon dioxide dissolves in alkaline sea water.Industrially carbon dioxide may be removed by:distillation of airchemical combination with materials such as NaOHA carbon dioxide scrubber, lithium hydroxide (Apollo 13) is used aboard spacecraft to remove carbon dioxide from the atmosphere2 LiOH(s) + 2 H2O(g) → 2 LiOH.H2O(s)2 LiOH.H2O(s) + CO2(g) → Li2CO3(s) + 3 H2O(g)
How does plankon function?
Plankton takes in carbon dioxide from the sea and stores it in its body. When plankton dies, it still has the carbon dioxide inside it, so has removed some of the problem from the ocean (problem for us). Without plankton, there'd be a lot more carbon dioxide and global warming would be worse.
Why does sea water absorb carbon dioxide?
Sea water absorbs carbon dioxide naturally as carbonic acid. The concentration is reduced by organisms like phytoplankton that fix carbon (use the carbon dioxide for photosynthesis) and release oxygen.
Is that salt concentration affects pH in sea water or fresh water?
No; the absorbed carbon dioxide is important.
