A grain of sand history

In class we are leaning about sand so these articles are taking what we learned and talking about one particular place where it is from. I am enjoying the articles and how the sand form Hawaii is different from the beaches around us or the ones we go to, The sand comes from tiny grains of rocks and the color. The beaches are made from pebbles and rocks. The beach waves deposits the sand and the gravel along the shore line. They become worn smooth from being rolled around all the time. They get rolled from the waves moving up and down.  The coastal processes modify the sand overtime. Sometimes little sand gets onto the middle of the beach but that happened a long time ago. The erosions of beaches happen more often after major storms and make it replenishment to look at it that way. People like to look at how the beach looks like when they go.  Hawaii beaches are the best beaches in the world because of the sand. The sand is white and beautiful. The teeth in their throats help break down to be able to be in the sand. The sand factories are producing 840 pounds per year. There is hundreds of tons of fish in the sand per year.  The beaches that we look at in the microscope are different colors and form different places. To me this is awesome to look at different places through the microscope to just look at the sand. Over all, the beaches sands that we look at are from different places, colors, and the shapes of each sand is through the microscope. I really enjoyed these articles because I learned a lot from them that I didn't know. I also enjoyed looking through the microscope to look at the sand to see what they looked like. 

Earth's movement

          We have learned many things in Oceanography about the plate’s movement. This is based off of the Earth’s lithosphere. The lithosphere is the outermost part of the shell. The things that make the plate tectonics move are the gravity, the stuff in the mantle, and the rotation of the planet. They make us move because of the energy that is making us move due to the movement. It makes up get new land because of the movement of the things that it makes us move. It makes us move the lower points to makes room for the new land. The movement of each movement makes the movement change. The separation of the plates makes each one a different movement. The rapid movement makes the plates move to different parts. It does that because of how they move because of each part that needs to be done. The low density of the movement moves then it is able to get a new one. The separation of each one happens after the mantle is able to get a new one. The movement depends on how hot the interior is will get how hot and how quick the interior movement takes.  The results of the movement determine if there will be any new questions. There are always new questions on how fast the movement is and how long it will take over time. It brings over time how the scientists figure out how the whole thing works but also why it will be happening. No matter what, over time the plates have moved and they will always be moving so we can have new plates underneath us. It happens because of the way earth is turning and how long it takes to turn over time. They will be able to form new ones all the time. 

Extra Credit

My opinion on this is that I liked it because of what they are telling us. I like how they took 50,000 photos to make it look 3-D. I can't believe a loaded vessel was found in 70 A.D. After it was loaded it crashed into a sheer rock wall on the island of Antikythera and then it sank. The ship had a huge array of precious objects like the richest cache that was found in the Mediterranean. The wreck was between 135 to about 150 feet deep and this made the diver only be able to spend a few minutes looking. I can’t believe they stayed with the Greek government and the reek government. They stayed at the Institution. They have a return to Antikythera that begins in September and end about October 12^th.   There are divers that visit about 114 years ago and 38 years ago. There is only a small portion of the wreck about 20 percent that was explored. They use a brass computer every day to look. The sites can be located everywhere. They use the 3-D maps to look at the bottom.  The humans can only go down 1,000 feet and stay on the bottom for 40 hours. They would have liked to do it remotely but they weren't able to do it. Over all, I really enjoyed this article and the facts.
