Question

How did the Gulf of Carpentaria form?

Answer 1

The gulf is the result of complexly interacting factors. In summer (November to April), with very flat land drainage, monsoonal rain, magnified tides, and wind piling up the sea on shore, the salt pan area is submerged by the sea, and behind it the land area is submerged by the drainage water backing up the blocked estuaries. The junction of saltwater and freshwater floods is marked by the transition from bare salt pan to vegetated plains.
