On 1/3/2019, S4 Geography class spent the afternoon on Sharp Island, hiking and learning about the geology and ecology of the island. The features sculptured by the nature are special and somewhat unique such as the tombolo and the “pineapple bun” formed by exfoliation. Plenty of volcanic and sedimentary rocks are found as it had once experienced violent volcanic eruptions about 140 millions of years ago. The island lies within Kiu Tsui Country Park and also the volcanic rock region of the Geopark. Going uphill and downhill in 2 hours was quite a challenge but the students made it with passion and perseverance. There are still more for all to explore!
