Paper 1 · People, Development and Environment
Consider the following statements. Statement 1: A carbon sink is a process or mechanism that removes carbon dioxide from the atmosphere. Statement 2: Oceans are the main natural carbon sinks; they absorb up to half of the carbon dioxide, due to phytoplankton. Statement 3: The largest sink (pollutant receptor) of the planet is the hydrosphere. Which of the following is correct?
- A carbon sink is a process that removes carbon dioxide from the atmosphere
- Oceans are the main natural carbon sinks, absorbing up to half the carbon dioxide due to phytoplankton
- The largest sink (pollutant receptor) of the planet is the hydrosphere
AStatements 1, 2 and 3 are true ✓ Correct
BOnly statements 1 and 2 are true
COnly statements 2 and 3 are true
DOnly statements 1 and 3 are true
Correct answer: (A) Statements 1, 2 and 3 are true — All three statements are true, so that is the answer.
Explanation
★All three statements are true, so that is the answer.
★A carbon sink is indeed a process that removes carbon dioxide from the air.
★Oceans are the main natural sinks, absorbing much carbon dioxide through phytoplankton.
★The hydrosphere is the largest pollutant-receiving sink of the planet.
★So each of the three statements is true.
★So statements 1, 2 and 3 are true.
