I'm not sure!
Coal is produced from the diagenesis of ______.
B) swamp vegetation
Coal was formed in swamp ecosystems which persisted in lowland sedimentary basins similar, for instance, to the peat swamps of Borneo today. These swamp environments were formed during slow subsidence of passive continental margins, and most seem to have formed adjacent to estuarine and marine sediments suggesting that they may have been in tidal delta environments. They are often called the "coal forests".
The type of weathering whereby rocks may be dissolved is called _______.
A) chemical weathering
