what is the typical depth range of a salt marsh?

0.5 - 1 foot
6 - 12 feet

Explanation:

First Question (About Salt Marsh Flooding/Draining Factor)

Salt marshes are coastal wetlands. Tidal action (rise and fall of tides) causes flooding and draining of salt marshes, defining their coastal wetland nature. Ocean currents don't directly flood/drain marshes, freshwater runoff from rivers is more for estuaries or freshwater wetlands, and seasonal rainfall isn't the primary coastal - driven factor.

Salt marshes typically have a shallow depth range. The typical depth range of a salt marsh is 0.5 - 1 foot. 1 - 6 feet is too deep for most salt marshes, over 12 feet is very deep (more like open water), and 6 - 12 feet is also deeper than typical salt marsh depths.

Answer:

A. Tidal action
