landforms and landscapes of deposition - estuarine mudflats and saltmarshes Flashcards
1
Q
the does deposition occur in river estuaries?
A
as water velocity is low so water can no longer carry its sediment in suspension
2
Q
where else may mudflats/saltmarshes occur?
A
in sheltered areas e.g. behind a spit
3
Q
what does deposition occur as a result of?
A
flocculation - lead to mud above the high tide level
4
Q
what colonises the transition zone?
A
pioneer plants
5
Q
what do pioneer plants in transitional zone lead to?
A
sediment becoming trapped
6
Q
when is a meadow formed?
A
as sections of the salt marsh rise above the high tide level
7
Q
when a meadow formed what does it lead to ?
A
climatic climax of the vegetation succession
