The oceans became shallower as part of the effects of global warming. The climate became drier and this has forced water to evaporate from the oceans.
Yes
Much of North America, and other parts of the globe were covered in ice that was as much as two or three kilometers thick. Remnants of those glaciers are still with us. And also to a lesser extent in some of the Earth's mountain ranges such as the Rocky Mountains.Much of the precipitation that originated as evaporation from the surface of the oceans fell as snow over the land and formed into glaciers. That was the reason the ocean levels were lower than they are today.
the oceans would become smaller
That is how you spell shallower (more shallow, less deep).
When deep water waves approach water shallower than half their wavelength, they are transformed into shallow water waves. These waves have shorter wavelengths and slower speeds due to interacting with the sea floor, causing their amplitudes to increase as the water becomes shallower.
Shallow, shallower, shallowest.
They are found worldwide, mostly in the shallower seas of the continental shelves. (Wikipedia)For the source and more detailed information concerning your request, click on the related links section (Wikipedia) indicated directly below this answer section.

The color of the ocean appears blue or green based on the amount of phytoplankton and the depth of the water. Oceans with less phytoplankton and deeper water tend to appear blue, while those with more phytoplankton and shallower water tend to appear green.
Water runs down hill where it gathers in low spots that become lakes oceans and seas.
when waves reach shallower the one half their wave length they begin to interact with the ocean floor
Comparative: shallower Superlative: shallowest
