Sea Eroded terrain
The northeastern coast is the area with the most developed sandstone sea erosion terrain. Except for Waiao, Xiaoao and Jianfangxikou which are beach terrains, the rest are all sea erosion terrains. The formation of sea eroded land is due to the alternating hard and soft rock formations. Under the long-term northeast monsoon and the erosion of big waves, strange and dangerous huge rocks and steep headlands were formed. The sea erosion terrain also includes sea erosion platforms, tofu rocks, single-sided mountains, sea erosion ditches and other different forms. The most peculiar sea-eroded terrain is the single-sided mountain or cuesta and tofu rock. A single-sided mountain is a terrain with steep one side and a gentle side due to the different hardness of the sedimentary rock; the formation of the block-shaped tofu rock is even more special. The rock layer must have two orthogonal joints to prevent the rock from being broken by the impact of the waves.
Sand eroded Terrain
In this area,the bay is a unique gift from God. On the beach, you can pick shells, catch crabs, pile sand sculptures, and experience drag fishing. Sit on the shore, while looking at the waves and rocks close by causing waves of waves, or you can also view the Turtle Mountain Island. The blue sea, white waves and the standing Turtle Mountain Island at a distance constitutes a beautiful beach scene. In addition, whistling pine trees windbreaks were planted along the dikes, and there are some yurts for catching eel seedlings at the tree-shaded areas inside the windbreaks; beach-raising areas are set up outside the windbreaks to formulate sand coast construction methods.
The Kuroshio is a warm current in the Pacific Ocean and the second largest ocean current in the world. The Kuroshio originates from the North Equatorial Current in the East Pacific Ocean. When the North Equatorial Current flows from east to west, it begins to split into two when it hits Luzon Island in the Philippines. The Kuroshio that flows northward along the east coast of Taiwan all the year round is what we call the “Kuroshio” and bypasses it. The Kuroshio tributary entering the Taiwan Strait from southern Taiwan. It was what the ancestors commonly called the “Black Water Ditch”
