Seascann

Seascann sa Pholainn

Is éard is seascann ann ná talamh fliuch faoi fhoraois.^[1] Meastar gur criosanna trasdula iad seascainn mar tá ról ag talamh agus uisce araon i gcruthú na timpeallachta.^[2] D'fhéadfadh fionnuisce, uisce goirt nó sáile a bheith sa seascann. Feictear seascainn fionnuisce ar bhruach aibhneacha nó lochanna móra, áit a mbíonn siad ag brath go mór ar uisce báistí agus ar thuilte séasúracha chun athruithe nádúrtha i leibhéal an uisce a chaomhnú.^[2]^[3] Is in aice le haibhneacha móra ar nós an Amasóin, an Mississippi, agus an Congó a fhaightear cuid de na seascainn is mó ar domhan.^[4] Feictear seascainn sáile ar chóstaí trópaiceacha agus fothrópaiceacha.^[5]

An difríocht idir seascann agus riasc

Is cineálacha sainiúla bogaigh iad seascainn agus riasca (nó corcacha) a fhoirmíonn i ngar do réimse uisce, in áiteanna a bhfuil ithir shaibhir sháithithe iontu.^[6] Is bogach é riasc a bhíonn faoi thuilte go leanúnach nó go minic, a bhfuil plandaí luibheacha chun cinn. Ar an lámh eile, bíonn ithir sháithithe agus/nó uisce bodhar i seascann, agus ó thaobh fásra de, is crainn, toir, agus sceacha uiscefhulangacha atá chun tosaigh. ^[7]^[5]
