The CCD is deeper in the Atlantic than in the Pacific since the Pacific contains more CO 2 , making the water more acidic and calcium carbonate more soluble.

During the day the sun heats up the land faster than it heats the water, setting up a convection cell of warmer rising air over the land and sinking cooler air over the water.

Those changes to our atmosphere have been no accident; over geological time, life and its metabolic processes have evolved (such as the evolution of photosynthetic bacteria that consume CO 2 ) and chang…

There is a great deal of concern about the greenhouse effect across the globe; not because of the presence of the effect itself, but because the effect is intensifying, causing climate change or global warming.

Over time, the erosion on the seaward side of the island, and the expansion of the marsh on the landward side, causes the island to slowly move towards the mainland, eventually closing off the lagoon.

Waves in the Southern Ocean are generally fairly large (the red areas in Figure \PageIndex2) because of the strong winds and the lack of landmasses, which provide the winds with a very long fetch, allowing them to blow unimpeded over the ocean for very long distances.

The continental shelf ends at the shelf break, which is the point where the angle of the seafloor begins to get steeper.

This depth is the compensation depth, and it marks the lower level of the photic zone, and represents the depth where net primary production ends.

The steeper slope causes the wave height to increase more rapidly, with the crest of the wave outrunning the base of the wave, causing it to curl as it breaks (left: JR, right: Andrew Schmidt, Public Domain [CC-0], publicdomainpictures.net).
