What happened in the picture above?
A) Turbulence where the rivers enter the sea has caused suspended sediment
in the seawater to flocculate and settle, forming the deposits seen on the right.
B) Rivers have delivered sediment to the sea, forming flat-topped deposits
called deltas.
C) Rivers have delivered sediment to the sea, forming deltas that built up as
they built out so that they still slope slightly downhill toward the sea.
D) Divers have built the mud piles to slow down the river water and protect
endangered clams that live along the coast.
E) A certain financially ailing airline that flies to Cincinnati and then Atlanta
built this from thrown-out beverage cups as an advertisement.
Feedback: Two deltas have formed where streams carry sediment from the

hillside into the fjord in South Greenland. The main source of sediment is the
streams from the land, not suspended sediment already in the sea water. And the
deposits cannot be purely flat-topped, or the rivers would not flow across to get to
the sea water in the fjord. Mollusks do live along the coast but are not being
protected by intrusive changes to the coastline, nor do enough people visit here
to be worth advertising Delta Airlines.
