Explanation / Answer

a. True. Bicarbonate buffers the stability of acid rain. HCO3-  is a weak base.

b. True. Ring of Fire is associated with convergent plate boundaries and the phenomenon of subduction.

c.True. The Appalachian Mountains were formed due to the convergence of the North American and North African tectonic plates.

d. True. At least 3 locations are needed to generate an approximate epicenter of an earthquake.

e. True. Carbonation is the process which takes carbon dioxide out of the atmosphere.

f. True. Subduction zones are created as a result of collision of 2 continental plates, and one subducting below the other.

g. True. The youngest ocean floor is found at divergent plate boundaries as mid oceanic ridges are created here due to the upwelling of the mantle. Consequently, sea floor spreading occurs.

i. True.

j. True

k. False. It is maximum in March.

l True.With increasing temperature, the solubility of CO2 in water decreases i.e. it becomes less soluble in water.
