Question

Select the pairs of sedimentary biogeochemical cycles. I. Hydrogen cycle and water cycle II. Phosphorus cycle and sulphur cycle III. Calcium cycle and magnesium cycle IV. Carbon cycle and nitrogen cycle

• A. I and II
• B. II and III
• C. III and IV
• D. I and IV

Answer 1

The Correct Option is B

Biogeochemical cycles can be grouped into $2$ types: (i) Gaseous cycle: Material involved in circulation are gases or vapours and the reservoir pool is the atmosphere or hydrosphere, e.g., nitrogen, carbon, hydrogen, oxygen and water cycle. (ii) Sedimentary cycle : Materials involved in circulation are non-gaseous and the reservoir pool is lithosphere, e.g., phosphorus, sulphur, calcium and magnesium cycle.
