True or false is this diagram an example of a short water cycle over the ocean? and how so?

Yes, it is. This is because the water from the ocean evaporates under sunlight, forming part of the clouds, and then rain falls from the same clouds back into the ocean.

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.
