Today in class, we learned the Hawaiian place names and some of the background of why it is called that specific name. I always thought the place names we know of was the original name but it wasn’t. Another thing that we learned and talked about was volcanoes tectonic plates across the globe. What we talked about was how the volcanoes erupt and how the plates shift and what happens when it does that, like Nanaku’ulei ,Pu’uheleakala, Ma'ili’ili and many more. An atoll is a fringing reef that forms around a volcanic island that subsides completely below sea level while the coral continues to grow upward, then an atoll is formed. A coral reef is an underwater ecosystem characterized by reef-building corals. About 30 minutes before lunch, we were working on to see the differences with climate change. What we did was we had two jars and what we had to do was put thermometers inside of the jar and one would be covered with saran wrap and the other would be open to see which one would get hotter.
