The Sulphur Cycle
The sulphur cycle is the biogeochemical cycle by which sulphur is exchanged within the biosphere. The cycle comprises both sedimentary and atmospheric components.
Statement 1: The sulphur cycle is completely sedimentary.
This statement is incorrect. The sulphur cycle comprises both sedimentary and atmospheric components. Sulphur exists in both organic and inorganic forms in the biosphere. Sulphur may be released into the atmosphere by volcanic activity or by human activities such as burning fossil fuels. Once in the atmosphere, sulphur may undergo a variety of chemical reactions before being deposited back onto the earth's surface.
Statement 2: Atmospheric sulphur dioxide is carried back to the earth after being dissolved in rainwater as weak sulphuric acid.
This statement is correct. When sulphur dioxide is released into the atmosphere, it reacts with oxygen to form sulphur trioxide, which then reacts with water to form sulphuric acid. This weak acid is carried back to the earth's surface in rainwater, where it may enter the soil and be taken up by plants.
Conclusion
Therefore, the correct answer is option B - statement 2 only. The sulphur cycle comprises both sedimentary and atmospheric components, but atmospheric sulphur dioxide is carried back to the earth after being dissolved in rainwater as weak sulphuric acid.
