High Island Field Trip

This week, grade 6  went to High Island in Hong Kong for a field trip. The purpose of the field trip was to look at the rock formation on High Island. Before, in High Island, there use to be magma.When the rocks cool down, it forms a really cool shape. Kind of a “S” shape along the wall. But its really called a hexagonal rock.

I think the field trip that we all took connects to the theme of our current unit because it affects life. The rock stratum could have a fracture in it and shift, which could cause multiple damage. When the rock stratum moves, it develops a fault. The fault could be crushed into fragments, which makes a breccia belt. There also use to have magma there, which makes hexagonal rock. When a rock cool quickly, it makes small columns. But when the rock cools slower, it will grow larger columns. With all these activities that have happened, I don’t think that it is a good place to live in.

I think the central idea connects to the field trip, because there was constant activity that have happened. Before, there was magma, which caused all the hexagonal columns. There isn’t any magma activities now a days. But with our tectonic plates constantly moving, it could hit our tectonic plate and cause another magma leakage. Which could be really dangerous for any nearby residence. Another thing that affects life on High Island, is that there is a reservoir. Since there is a reservoir, and there is only fresh water, there isn’t any food they can fish. Which makes finding food a lot harder. Although there could be near by animals, which people can kill for food. But I don’t see a lot of nearby.
