Question
Which of the following processes does NOT provide carbon to the atmosphere?
- Volcanic eruptions
- Respiration
- Weathering of limestone
- Subduction
Hint:
Subduction
The correct answer is: Subduction
Thick layers of sediment may accumulate in the trench, and these and the subducting plate rocks contain water that subduction transports to depth which at higher temperatures and pressures enables melting to occur and magmas to form.
