Where do organic deposits typically form?

Organic deposits typically form in bogs, swamps, or marshes due to the specific environmental conditions found in these areas. These environments are characterized by waterlogged soil, which limits the oxygen available for decomposition. As a result, plant material accumulates over time without fully breaking down, leading to the formation of organic deposits such as peat.

The anaerobic conditions found in wetlands create an environment where organic matter can accumulate significantly, supporting a rich diversity of plant and animal life while fostering the development of layers of decomposed vegetation. This contrasts with river valleys, sandy beach ridges, and mountainous regions, where the conditions are not conducive to the accumulation of organic matter in the same manner as wetlands.
