Why can seashells be found at the top of Moon Hill, Yangshuo? AF 4 – explain the processes involved in the formation of landforms In groups, read through the information and study the images, then place the information into the correct order. Be prepared to share the order with the rest of the class. Encourage students to write the extended answer as this will enable them to apply more explanation

Why can seashells be found at the top of Moon Hill, Yangshuo? Using the information, answer the question by completing one of the following activities: WTE - Label the images using the information given ME - Annotate the images by explaining in your own words using connectives i.e. ‘because’ EE - Write an extended answer to this question in detail using connectives i.e. ‘because’ and ‘this means that’ and use evidence.

Peer Assessment How could you improve the following? 300 million years ago, Yanghsuo was a marine environment (underwater). The fish died, sank to the bottom of the sea and because of this, the sediment built up in layers. 300 million years ago, Yanghsuo was a marine environment (underwater). The fish died and due to this, deposited on the sea bed. As a result, the sediment built up in layers at the bottom of the sea. The sediment includes dead fish, plants, rocks, sand etc… WTE - Label the images using the information given ME- Annotate the images by explaining in your own words using connectives i.e. ‘because’ EE- Write an extended answer to this question in detail using connectives i.e. ‘because’ and ‘this means that’ and use evidence.

Peer Assessment AF 4 – explain the processes involved in the formation of landforms Swap your work with a partner. Peer assess the answer using the success criteria. Success Criteria TICK EE - You have explained the answer to this question using ‘because’ and ‘this means that’ to develop my points in detail. You have used evidence. ME- You have written my own simple explanation using ‘because’ WTE- You have labelled the diagrams using the information given. Make a comment on the following: + What is good about the piece of work? (use the success criteria to help you) -> TARGET – How could the piece of work be improved? What could be done next time?

Why can seashells be found at the top of Moon Hill, Yangshuo? What type of rock is Yangshuo made up of?

Limestone

Discuss the formation of the landscape – how do they think it was all formed?

300 million years ago, Yangshuo used to be under water.

Rock is weathered and moved by erosion, then transported by ice, water or wind. The bits of rock are called sediment. Sediment = stones/sand/shells/rock Weathered = broken up sediment

Overtime the deposition of sediments like fish bones, shells and bits of rock build up on the seabed. Deposition = material is being dropped

More layers of sediment are deposited More layers of sediment are deposited. These compact (squash) the sediments below them forming sedimentary rock - limestone. Compaction squeezes the water from between the grains.

Major earth movements pushed up the seabed and the sea level dropped to expose the limestone. These earth movements also formed the Himalayas far to the West.

The heavy monsoon rain, sometimes exceeding 2000mm, has led to rapid erosion of the land by rivers such as the Li River (Li Jiang) Rapid erosion = water cutting into the land quickly

Today, the limestone rock rise up to over 500 metres above sea level forming a Karst scenery.
