Name four extensions of water around mexico and central america

There are multiple extensions of water in Mexico and Central America, some of which are the Gulf of Mexico, Gulf of Honduras, Gulf of Fonseca, Gulf of Panama...

The extensions of water, simply, are bodies of water that are connected with a bigger body of water, but they are going more inland, and are surrounded on two or three sides by land.

The gulfs are prime example for extensions of water, with the Gulf of Honduras being an extension of the Caribbean Sea, while the Gulf of Fonseca being an extension of the Pacific Ocean for example.

since there isn't any suggested answers i will give you the reason and hopefully you can figure it

south africa, or rather all of africa, has not been in the location in which it is nowadays throughout the geological past. after the super-continent pangaea started to break apart, gondwanaland, in which was africa, moved further south, and parts of it came to be very close to the south pole. because the climate in this part of the world is very cold due to the very dispersed sun rays in there, what is now south africa, started to freeze, and the conditions were right for the formation of glaciers. the glaciers existed up until the period when gondwanaland started to break apart and what is now africa started to move towards north, sp it warmed up and the glaciers melted.
