What characterizes a muddy shore in terms of slope and particle size?

A muddy shore is characterized by a gentle or nearly flat slope and consists predominantly of very fine particles like silt and clay. This environment supports the accumulation of mud due to minimal wave action and currents, allowing fine particles to settle and build up over time. The lack of steep gradients facilitates the presence of standing water during high tides, creating an ideal habitat for various organisms adapted to such conditions.

The choice highlighting a slope that is little to no slope with the smallest particles accurately reflects the typical characteristics of muddy shores. These shores are often found in environments like estuaries, where sediment can accumulate due to low energy conditions.
