Shore Erosion and Distribution of Sediments

The floor of the sea was first formed or rocks that had cooled from a state of fusion. The few islands that existed were but exposed portions on the floor. The debris scattered over this foundation would be arranged in layers, as water always arranges its sediments. The coarser materials would be transported by the more powerful action and deposited in one place. The finer materials would be carried beyond and deposited in a remoter region. Here we see (a) the primordial igneous crust, (b) a sea-side cliff gnawed by the waves, (c) the ordinary sea-level, (d) the ruins of the cliff with the coarser deposited near the shore, and the finer floated to greater depths.
