GEOGRAPHY

On 18th November 2015, a group of Year 7 students visited the Hong Kong Geopark in Sai Kung, studying the coastal landforms and geology in the High Island Reservoir area. We visited the East Dam, which was built for the reservoir to provide a source of freshwater supply within Hong Kong.

Under the bright sunshine, everything looked spectacular. The Po Pin Chau stack looked much more intriguing than those in our textbooks. And we saw the hexagonal rock columns which were magnificent. According to the Geopark officers, those hexagonal columns were formed due to contraction in the cooling process of lava. The most famous S-shaped rock section looked so remarkable and astonishing. It was formed due to the ‘subsidence’ of the rock under gravity before the lava cooled and solidified.

I now understand better the geological history of the area and the formation of these landforms. Compared to conventional classroom learning, the field trip was much more meaningful as I was able to ‘touch’ and ‘see’ the knowledge and theories in such an authentic learning.
