Sand Reflection

By doing the sand activity i learned a lot about the formation of different types of sands based on where they are geologically. In this assignment i studied eight different types of sand and found that they all had very different origins. One of the samples that i would like to talk about is my sand sample from Maui. This sand was very fine and it had a black color to it. I knew the reason for this was because Maui is located near volcanoes so the sand is a product of the volcano. I also know that the location of the sand is near a subduction zone, that is another reason why the sand appears the way it does. One other beach that i looked at was the Bahamas. This sand was glossy white and had a lot of organisms in it. Also the sand was well sorted and large. It was much different than the sand in Maui and this is because this sand is located in the Caribbean which is not near a subduction zone. Also i have found two new questions to ask after doing this assignment. One would be, how does the location of the sand effect its appearance? The other question would be, how long does it take a certain area to have just one type of sand? Overall, i learned a lot from this activity and i am glad that i was able to do it.
