Question

1. which of the following is considered a carbon sink?

the desert
the ocean
titusville, pa
the amazon rainforest

Explanation:

A carbon sink is a natural or artificial reservoir that accumulates and stores some carbon - containing chemical compound for an indefinite period. The Amazon rainforest is a major carbon sink as it absorbs large amounts of carbon dioxide through photosynthesis. The desert has limited vegetation and thus less carbon - sequestering ability. Titusville, PA is a city and not a natural carbon - sequestering entity. While the ocean is also a carbon sink, the question asks for the option among the given ones and the Amazon rainforest is a well - known terrestrial carbon sink.

Answer:

the Amazon rainforest
