Today we are learning about how sedimentary rocks are formed and deposited. Mr Riley told us that Mt Cook would have been 20km higher than it is today if it hadn’t been for erosion UNBELIEVABLE :). The rocks are moved by Rivers,Wind and Sea. When they have been moved they are deposited in layers with the oldest at the bottom. We are now doing a table to find out the features and formation of the rocks. Alot of the rocks were formed in a river and a couple were from sand and swamps.
