Dyma fi eto.
A oes gwahaniaeth pendant rhwng y ddau air hyn yn y Gymraeg?
Mae'r dewisiadau a gynigir yn debyg iawn yn y geiriaduron.
A bog is a wetland type that
accumulates acidic peat, a deposit of dead plant material.
A marsh is a type of wetland,
featuring grasses, rushes, reeds, typhas, sedges, cat tails, and other
herbaceous plants (possibly with low-growing woody plants) in a context of
shallow water.
A marsh is different from a swamp,
which has a greater proportion of open water surface, which is generally deeper
than a marsh
A bog can be referred to as a swamp
while a marsh technically can not. Also the acidic waters of a bog distinguish
it as being different than a marsh.
Diolch
