  6. What type coastal feature is it?Beach • Describe the location of the beach in relation to the headland.It is a bay-head beach which lies at the head of a bay between 2 headlands. • Estimate the size of the beach.About 1.02Km • What are the main materials that formed the beach?Sand, pebbles • Which direction is the beach facing?South or SSE • What facilities are provided to the beach-goers?Toilets,washing rooms,shops…… • What are the unfavourable factors to develop Shek O as a major tourist resort in HK?the transportation network is not well-developed.

  7. Stop 2: Shek O Headland

  8. Name the type of rock in the headland.granite • The rocks along the coast are being weathered/eroded.Suggest the erosional agents to the formation of the feature.Sea water ,waves • What weathering processes are being taken place in the area?Hydraulic action, abrasion, attrition, solution • Looking at the offshore island in the southern side of the headland. It is Ng Fan Chau. What coastal feature(s) can you find on the island?Block disintegration, cracks and Sea caves

  12. Describe the materials you can find around this area.Sand,rock,boulders,pebbles • Measure the size of materials in 2 different locations-one is on the southern shore and another is on the northern shore.Is there any difference between the size of materials?In the north,the materials are smaller but in the south,the materials are larger. • Name the coastal feature formed in the area.Tombolo

  13. Tombolo

  14. A simple sketch diagram.

  15. The formation of tombolo • The two islands (HK islands and Tai Tau Chau)provide shelter to the shallow sea in between against the prevailing winds. • Then the longshore drift brought in materials and deposited them in slack water. • A sand spit is formed on each island. • As the 2 sand spits continue to grow longer, the finally join up. • The two separate islands are linked up to form a tombolo.

  16. Stop 4 Tai Tau Chau

  17. On Tai Tau Chau, you can see a rock which is affected by denudation.Identify the type of weathering process being take place. • Block disintegration

  18. A sketch diagram

  19. What is the coastal feature formed in the southern part of the headland?Geo • Estimate the height of the feature.Not clear,about 100metres • List out the favourable factors for its formation. • It is exposed coast with long fetch and deep coastal water.Destructive waves are common.Therefore, there is wave erosion. • At the Tai Tau Chau pavilion, try to look around and see whether you know the names of surrounding land and sea.We can see Tseung Kwan O in the north.Shek O headland and Ng Fan Chau in the south.
