Before last class time’s discussion I was totally confused! I wasn’t exactly sure why the island sinks so I assumed it was because of the weight of the coral. I now understand that it is because of the weight of the magma. (the coral is just a contr…
There isn't much that was cleared up for me during last class, because I had taken it the exact way that it was intended from the class before it. However, I learned a few things that basically just clarified what I already knew. The idea that Mr. N…
When we covered Midway in class, the whole atoll idea really set in. Once I made the connection between Midway and atolls, I immediately understood them a lot better. The whole idea that we bombed one is amazing still, but if you think about it, we…
Very true I guess but if nothing else, this proves it. And also, if they did not do this, it could have been just another resort island where people come and go all the time so the coral would have been killed or damaged.
Last Monday's class cleared up how the atolls sank, the coral is not the major cause of their sinking, it is the weight of the magma that comes out of the volcano. I was confused about how the coral weighed this much, but this cleared it up for me.
One thing that really was cleared up for me last class was the fact that reefs don't cause islands to sink. It is caused by the magma moving underneath the surface of the plate. I also thought it was cool that there are more islands to Hawaii than w…
Awesome video. But that music drives me INSANE. I can't take it. :X Were pretty much on the same page. I had know idea the process it took to make an atoll. 300,000,000 years seems like a looooooooong time for something to form. But when you see pic…
Awesome video. I forgot all about that.
;)
And yes... atolls are "rare" in terms of the total surface area of the Earth in which they cover. However, in some areas (the South pacific) they are certainly relatively more common. I too concur- I have…
Well... yes and no. A "barrier reef" certainly IS a stage of reef/atoll formation. However, the Great Barrier Reef in Australia, as well as the Florida Keys/Bahamas are a different sort of "barrier reef" in many ways. You are all doing a good job of…
While there are a lot of good things about the reefs to talk about and analyze in a much greater depth, I will only talk about those in a few short sentences. In truth, most of this stuff we learned about with the reefs themselves, I learned when we…
