Coal is formed in swampy environments with abundant plant material that accumulates and is buried over time. The plant material undergoes the process of diagenesis, where heat and pressure transform it into coal.
Coal is typically formed in swamp environments, where abundant plant material accumulates and is buried over time. The anaerobic conditions in these swamps prevent the complete decay of the plant material, leading to its transformation into coal through a process called coalification.
High depositional environments include deltas, beaches, and river channels where sediments accumulate rapidly. In contrast, low depositional environments such as deep ocean basins, where sedimentation occurs slowly due to reduced sediment input and energy, leading to finer-grained deposits.
Bituminous coal fields were formed millions of years ago from the remains of ancient swamp forests that were buried by layers of sediment. Over time, heat and pressure transformed the organic material into coal. The presence of specific geologic conditions, such as tectonic activity and depositional environments, also played a role in the formation of bituminous coal fields.

Depositional environments of rivers include floodplains, deltas, and alluvial fans. In these environments, sediment transported by the river is deposited due to a decrease in flow velocity, allowing the formation of landforms such as beaches, bars, and levees.
Eskers were formed by depositional processes. They are long, winding ridges of sand and gravel that were deposited by meltwater streams flowing in tunnels beneath glaciers during the last Ice Age.

Depositional environments are specific locations where sediment is deposited and accumulated, leading to the formation of sedimentary rocks. These environments can include riverbeds, shorelines, deltas, and ocean floors. They provide clues about the conditions under which the sediments were initially deposited.
Coal formed in ancient swamp environments, where plant material accumulated in oxygen-poor conditions, allowing for its preservation and transformation into coal over millions of years.
the reason is because rocks can have different depositional environments and diagenesis history.
