We never thought that the water has such a great impact on the coasts and the limestone. It's even more incredible that landforms can be shaped differently according to the type of resources. It is a very rare sight as we have never seen these before in Singapore.
Waves and rain are the agents of the formation of landforms at Ha Long Bay. Waves approach the different resistance rocks on the coast resulting in different rates of erosion. Less resistance rocks will erode faster and form a bay overtime. More resistant rocks will protrude out of the coastlines and this is known as headlands.
Waves contain carbonic acid, from the rain or the composition of plant matter, which dissolves calcium carbonate in the limestone and collapse to form a cave. Rain pound against the surface of the limestone and dissolves it leaving behind stalagmites and stalactites that resembles icicles.
