Earth's mantle has kept contributing to the Earth's atmosphere through a process called degassing. During this process, gases are emitted from the magma in the mantle and are transferred into the atmosphere through tectonic procedure such as ocean ridge spreading and volcanism.
Two plates that are made up mostly of oceanic crust are the Pacific plate and the Nazca plate.
Explanation:
There are numerous tectonic plates that divide the surface of Earth, and they can be divided into oceanic plates and continental plates. Another division commonly used is major plates. minor plates, and micro plates. The oceanic plates are plates that are mostly made up of oceanic crust, and the land masses on them are consisted of island arcs, mostly of volcanic origin. Some of the oceanic plates are:
- Pacific plate
- Nazca plate
- Cocos plate
- Caribbean plate
- Scotia plate
The Pacific plate is the largest oceanic plate, and it is a major plate. It is dominated by ocean, with numerous island chains scattered across it. This plate is shrinking from all sides as it has subduction zones with all of the continental plates that surround it. The Nazca plate is another oceanic plate, being located between the South American and Pacific plates. It is a minor plate, and it has a subduction zone with the South American plate, which has resulted in the formation of the Andean Mountain Range.

Answer: mid ocean ridges so I would go with the first one of at the spreading centers in the middle of the ocean
