12. how do sedimentary rocks contribute to cycle? a. by absorbing carbon dioxide from atmosphere b. by…

Brief Explanations:

Sedimentary rocks trap and store carbon over long - geological periods as sediments accumulate and are compacted. This is an important part of the carbon cycle. They do not primarily absorb carbon dioxide from the atmosphere like plants (option a is incorrect), and they do not convert carbon into organic matter in the way living organisms do through photosynthesis or other biological processes (option c is incorrect).

Answer:

b. by storing carbon over long periods
