Animation of the Formation of an Atoll

[edit]
Original - This animation shows the dynamic process of coral atoll formation. Corals (represented in tan and purple) settle and grow around an oceanic island, forming a fringing reef. In favorable conditions, the reef will expand, and the interior island will subside. Eventually the island completely subsides beneath the water, leaving a ring of growing coral with an open lagoon in its center. The process of atoll formation may take as long as 30,000,000 years to occur.
Reason
Not many people know what an atoll is. This is a simple explanation in a picture. Also, it is original.

  • Oppose (to try to get this started). Very useful and informative, but I don't see anything stunning in quality and presentation. I know there's no official limit on size with animations, but 320 × 237px, and total file size of 38kB - well compare that to what we expect of photos. Things such as the detail in colouring and textures are very basic, as is the quality of the illustrations themself. There also seems to be slightly varying definitions of what an atoll is, which don't necessarily consist of having a fully open lagoon within the fringing reef (though that clearly is one accepted definition). And this illustration appears to indicate that as the island erodes the reef builds up, suggesting that the reef is formed from the eroding island itself - I know that's not what it's intending to illustrate, but that's rather how it appears. --jjron (talk) 12:06, 14 March 2008 (UTC)[reply]
  • Oppose: I agree with Jjron - I don't think that the illustration gets it quite right, and I think the land as a whole generally subsides, but the coral builds up atop the shells of the old coral to keep at the proper depth, forming the ridge.
