Transcript: Ocean Acidification Background How do organisms on earth produce Co2? How do organisms on earth produce Co2? By burning fossil fuels Humans burn many fossil fuels on a daily basis which come from gas,oil and coal The burning of these fossil feuls are responsible for 87% of human Co2 emissions Burning of fossil fuels realese energy but Co2 also gets produced as a byproduct. By burning fossil fuels How has the amount of Co2 increased over the last ... How has the amount of Co2 increased over the last 20 years? The amount of Co2 in the atmosphere has drastical... The amount of Co2 in the atmosphere has drastically increased over the past 20 years which has caused the oceans acidity level to rise as well.This has caused many changes in the atmosphere as in how much Carbon certain things can take in and give off. How and why does Co2 get absorbed into the ocean? How and why does Co2 get absorbed into the ocean? Carbon is stored in the ocean as a part of the carbon cycle th... Carbon is stored in the ocean as a part of the carbon cycle this happens because all of the Co2 that organisms are giving off has to be stored somewhere and unfortunetly because there has been an increase in Co2 emissions the ocean has to intake some of the Co2. What changes do the oceans undergo because th... What changes do the oceans undergo because they absorb excess amounts of Co2? One of the most drastic changes that the oceans has to ... One of the most drastic changes that the oceans has to go through is the raising of it's acidity level which sends a threat to the fish and other animals in the ocean.This puts the dynamic equilibrium off balance because there is too much Co2 coming in to the ocean and not enough being released.The increase of Co2 in the ocean has been known to cause higher water temperatures. What effect does Co2 in our oceans have on PH? What effect does Co2 in our oceans have on PH? Ph is the measure of the hydrogen i... Ph is the measure of the hydrogen ion concentration in a solution which consist of acids(0-7) and bases(7-14). The oceans ph is averaging 8.2 ph units According to national geographic the oceans take in about 1/3 of human created Co2 emissions which is about 22 million tons each day. If these emissions continue at the rate they are going the oceans ph could be reduced by 0.5 units. Many fish can be put in danger because of the unusual level of ocean acidity. If the ocean coninues to absorb this much Co2 it's capacity will soon diminish. What is the carbon cycle? What is the carbon cycle? The carbon cycle is the circulation of co2 between living organisms The carbon cycle is related to the additional Co2 in the atmosphere because there are certain organisms that grow and decompose quickly and give of lots of Co2. A lot of the carbon that is on earth goes through the carbon cycle very quickly. The carbon cycle is the circulation of co2 betwe... How does the addition of Co2 disrupt the ocean's equilibrium? How does the addition of Co2 disrupt the ocean... When the ocean has to store more Co2 it takes more time to reach equilibrium. It usually takes a long time for the ocean to cycle carbon back into the atmosphere Le Châtelier's principle is working because because the Co2 is being exchanged and trying to maintain balance.

Transcript: Created by Destini Perkins Ocean Acidification How Organisms are producing C02 on Earth How Organisms are producing C02 on Earth As we know CO2 comes from the burning of fossil fuels. One way we are producing CO2 is through Industrial Agriculture. The US food system contrubutes about 20 perecent of the nations CO2 emissions. Over the past 20 years the amount of carbon dioxide has steadily increased and has hit its record high. HOW and WHY does CO2 get absorbed into our oceans? HOW and WHY does CO2 get absorbed into our oceans? The atomosphere that carries carbon dioxide, slowley, but surely dissolves the CO2 in the surface waters of the ocean. Some of CO2 stays as a dissolved gas as well reacting with H20 to form carbonic acid. Gas is a main factor contributing to CO2 entering the ocean. What changes do the oceans undergo because they absorb excess amounts of CO2? What changes do the oceans undergo because they abso... Changes tat the ocean undergos from absorbing excess amounts of CO2 is put into the oceans carbon balance. Weak acids and bases exchange hydrogenions in seawater, which are responsible for controlling the oceans pH. this ties into the oceans dynamic equilibrium because of the amount of acids and bases need to meet at equlibrium. yes, these changes caused an increase in temperature. What effect does CO2 in our oceans have on pH? What effect does CO2 in our oceans have on pH? CO2 changes the oceans ph and disrupting the oceans eqilibrium by unbalancing the bases and acids. The effect of the CO2 in the ocean is slowly killing off small living organisms at the bottom of the sea. ex): coral, mussles etc... There is no "healthy" amount of CO2, these organisms are living in dead zones with little oxygen and cannot survive. pH= a figure expressing the acidity or alkainty of a soulution on a scale. 7 being neutral, lowest being more acidic while higher meaning alkaline/basic. To calculate the pH you start at neutral and add or deduct CO2 from the concentration. Carbon cycle consists of carbon compounds within the enviroment involving photosynthesis and returning to the atmosphere through respiration decay of dead organisms and burning of dead fossil fuels. This cycle is related to our atmosphere because carbon intertwines with plants. Once plants die they are burried carrying the CO2 which we later burn the fossil fuels from the plants. What is the Carbon Cycle? What is the Carbon Cycle? Le Chatelier principle intertwinds with the disrupt of the oceans equilibrium because of the conditions' "increase of CO2". These conditions are unstabilizing the equilibrium state. This is causing the pH change and unstability in the ocean. Carbonic acid is a crical part to the oceans equalibrium; which is divided within two parts (Solubility of Calcium Carbonate & Dependent Carbonate Equilibrium). Carbonic acid is formed when atmospheric CO2 is dissolved in water which is disrupting the oceans equilibrium. How does the addition of CO2 disrupt the ocean’s equilibrium?
