Answer;
-More carbon dioxide causes an increase in carbonic acid (H2CO3) which leads to a decrease in the concentration of carbonate ion (CO32-).
Explanation;
-Carbon dioxide is added to the atmosphere whenever people burn fossil fuels. Oceans play an important role in keeping the Earth's carbon cycle in balance.
-As the amount of carbon dioxide in the atmosphere increases, the oceans absorb a lot of it. In the ocean, carbon dioxide reacts with seawater to form carbonic acid which causes the acidity of seawater to increase.
-As long as we keep putting extra carbon dioxide in the atmosphere, the acidity of the ocean will continue to increase. The effect is that; Increasing acidity makes it harder for corals to build skeletons and for shellfish to build the shells they need for protection. Corals are particularly important because they provide homes for many other sea creatures.

Answer:
Explanation:
Gravity:
It is the force by which the elements of matter pulls together.
Explanation:
The gravity is depend upon the mass of matter. The more mass of object the more will be the gravitational force.
The earth is most heavier than all other matter that's why all matter pulls towards the earth.
For example;
when we walk on the earth, it pull us. Our mass is less as compared to the earth that's why we fall back on the earth instead of moving upward because our pull is negligible because of greater difference in masses. The earth mass is very high.
The gravitational force is inversely proportional to the square distance of interacting objects.
As the two objects are more distance apart from each other the less will be the gravitational force.
